Before a research group can use LSDYNA on sharcnet, a license must be purchased directly from LSTC for the sharcnet license server.  Alternately, if a research group resides at a institution that has sharcnet computing hardware (mac, uwo, guelph, waterloo) it maybe possible to use a pre-existing site license hosted on an accessible institutional license server.

These usage instructions apply to the module based installation of lsdyna found under directory <i>/opt/sharcnet/lsdyna</i> on licensed clusters shown in the above Availability Table.  To access and use this software you must be a member of the <b><i>lsdyna</i></b> group. Users who belong to a licensed department will be given a 5 digit port number.  The value should then be inserted into the appropriate departmental export statement before loading the module file as follows:

===License===
−
<source lang="bash">export LSTC_LICENSE_SERVER='PortNumber'@license1.uwo.sharcnet</source>

Create and customize this file for your license server, where XXXXX should be replaced with your port number and Y with your server number:
 +
 
 +
[roberpj@gra1:~] cat .licenses/ls-dyna.lic
 +
#LICENSE_TYPE: network

===Module===
 +
 
 +
The modules are loaded automatically in the testomp.sh and testmpi.sh script shown below in the example section:
 +
 
 +
For single node smp jobs the available versions can be found by doing:
 +
 
 +
[roberpj@gra-login2:~] module spider ls-dyna
 +
        ls-dyna/7.1.2
 +
        ls-dyna/7.1.3
 +
        ls-dyna/8.1
 +
        ls-dyna/9.1
 +
        ls-dyna/9.2
 +
        ls-dyna/10.0
 +
 
 +
To load any version do for example:
 +
 
 +
module load ls-dyna/9.1
 +
 
 +
For multi node mpp jobs the available versions can be found by doing:
 +
 
 +
[roberpj@gra-login2:~] module spider ls-dyna-mpi
 +
        ls-dyna-mpi/7.1.2
 +
        ls-dyna-mpi/7.1.3

 +
        ls-dyna-mpi/9.1
 +
        ls-dyna-mpi/9.2
 +
        ls-dyna-mpi/10.0
 +
 
 +
To load the 7.1.X modules do the following:
 +
module load openmpi/1.6.5 ls-dyna-mpi/7.1.3
 +
 
 +
To load the 8.X or 9.X modules do:
 +
module load openmpi/1.8.8 ls-dyna-mpi/9.2
 +

To run the single or double precision solvers specify <strong>lsdyna_s</strong> or <strong>lsdyna_d</strong> respectively:

=Job Submission=
 +
 
 +
==Graham Cluster==
 +
 
 +
The submission scripts myompjob.sh and mympijob.sh for the airbag problem are shown in the <b>Example Job</b> section below, for both graham and orca.  Please note that you should specify your own username if submitting to a def account (not roberpj).  Alternatively you could specify your resource allocation account:
 +
 
 +
Sample threaded job submit script:
 +
 
 +
sbatch myompjob.sh
 +
 
 +
Sample mpi job submit script:
 +
 
 +
sbatch  mympijob.sh
 +
 
 +
==Legacy Clusters==
 +
 
 +
When loading a lsdyna sharcnet legacy module on the new orca or a sharcnet legacy system, the single or double precision solvers are specified with <strong>lsdyna_s</strong> or <strong>lsdyna_d</strong> respectively, as shown in the following sqsub commands:
 +
 
 +
===1cpu SERIAL Job===
 +
<pre>sqsub -r 1h -q serial -o ofile.%J --mpp=2G lsdyna_d i=airbag.deploy.k ncpu=1</pre>
 +
 
 +
===4cpu SMP Job===
 +
<pre>sqsub -r 1h -q threaded -n 4 -o ofile.%J --mpp=1G lsdyna_s i=airbag.deploy.k ncpu=4</pre>
 +
 
 +
If using an explicit solver, one can specify a conservative initial memory setting on the command line as follows:
  
−
o SUBMIT 1CPU SERIAL JOB
 
 
<pre>
 
<pre>
−
sqsub -r 7d -q serial -o ofile.%J --mpp=2G lsdyna_d i=airbag.deploy.k ncpu=1
+
export LSTC_MEMORY=auto
 +
sqsub -r 1h -q threaded -n 4 -o ofile.%J --mpp=2G lsdyna_d i=airbag.deploy.k ncpu=4 memory=754414</pre>
 +
where memory is the minimum number of 8 byte words shared by all processors in double precision, or, 4 byte words in single precision.
 +
 
 +
The initial value can be determined by starting a simulation interactively on the command line, and finding the output resembling: <i> Memory required to begin solution      :      754414</i>.    The number of words can be specified as memory=260M instead of memory=260000000,  for further details see https://www.d3view.com/2006/10/a-few-words-on-memory-settings-in-ls-dyna/. 
 +
 
 +
===8cpu MPI Job===
 +
 
 +
<pre>sqsub -r 1h -q mpi -o ofile.%J -n 8 --mpp=2G lsdyna_d i=airbag.deploy.k</pre>
 +
 
 +
The initial memory can also be specified for mpi jobs  on the sqsub command line with "memory=" for the first master processor to decompose the problem  and "memory2=" used on all processors including the master to solves the decomposed problem, where the values are specified as 4 bytes per word in single precision and 8 bytes per word in double precision.  The number of words can be specified as memory=260M instead of memory=260000000 OR memory2=260M instead of memory2=260000000 for further details see https://www.d3view.com/2006/10/a-few-words-on-memory-settings-in-ls-dyna/.  The initial values can be found by running simulation interactively on a orca compute node and checking the output for a line such as: <i>Memory required to begin solution (memory=    464898  memory2=    158794 )</i> which could then be implemented for a job run in the queue by doing:
 +
 
 +
<pre>
 +
export LSTC_MEMORY=auto
 +
sqsub -r 1h -q mpi -o ofile.%J -n 8 --mpp=2G lsdyna_d i=airbag.deploy.k memory=464898 memory2=158794
 
</pre>
 
</pre>
  
−
o SUBMIT 4CPU SMP JOB
+
The specification of memory2 on sharcnet or compute canada clusters is not beneficial since the queue reserves the same memory per core for all nodes, such that the decomposition master node process cannot be allocated to have larger system memory.  Therefore its sufficient to specify a single memory parameter by doing:
 +
 
<pre>
 
<pre>
−
sqsub -r 7d -q threaded -n 4 -o ofile.%J --mpp=2G lsdyna_d i=airbag.deploy.k ncpu=4
+
export LSTC_MEMORY=auto
 +
sqsub -r 1h -q mpi -o ofile.%J -n 8 --mpp=2G lsdyna_d i=airbag.deploy.k memory=464898
 
</pre>
 
</pre>
  
−
o SUBMIT 4CPU MPI JOB
+
where the LSTC_MEMORY variable will only allow the memory to grow for explicit simulations. The following slurm examples demonstrate how to prescribe the memory parameters exactly.

To run the sharcnet legacy <i>module lsdyna/mpp/r712.95028</i> efficiently over several compute nodes with many cores requires using orca's xeon nodes as shown in <b> mympijob4.sh</b> below.  To run lsdyna on orca's opteron nodes with <i>module lsdyna/mpp/r712.95028</i> requires using only <b>one</b> opteron node as shown in <b> mympijob5.sh</b> below.  The other legacy sharcnet lsdyna mpp modules, as shown in the Availability Table  lsdyna/mpp/ls971.r85718, lsdyna/mpp/ls980B1.011113, lsdyna/mpp/r611.79036, lsdyna/mpp/r611.80542, lsdyna/mpp/r711.88920, lsdyna/mpp/r800.95359 and lsdyna/mpp/r901.109912 have yet to be tested. If you want to use one but cannot get it working please open a ticket.  Note that lines containing a space between "# and SBATCH" are comments.  To activate such line(s) required removal of the space ie) "#SBATCH".  Its recommended to use <i>module ls-dyna-mpi</i> on graham instead since the machine is far newer, faster and reliable.

STEP1) The following shows sqsub submission of the [http://www.dynaexamples.com/examples-manual/misc/airbag airbag] example to the mpi queue. Its recommended to first edit  <i>airbag.deploy.k</i>  and change <i>endtim</i> to 3.000E-00 so the job runs long enough to perform the restart in steps 2 and 3 below:

 +
 
 +
 
 +
==Command Line Use==
 +
 
 +
Following the upgrade of orca to the compute canada module stack, the orca development nodes were discontinued.<br>
 +
Therefore this section is no longer relevent and remain for historical purposes only.
 +
 
 +
Parallel lsdyna jobs can be run interactively on the command line (outside the queue) for short run testing purposes as follows:
 +
 
 +
o Orca Development Node MPP (mpi) Example
 +
 
 +
ssh orca.sharcnet.ca 
 +
ssh orc-dev1  (or dev2,3,4)
 +
module unload intel openmpi lsdyna
 +
module load intel/12.1.3 openmpi/intel/1.6.2 lsdyna/mpp/r711.88920
 +
mpirun -np 8 lsdyna_d i=airbag.deploy.k
 +
 
 +
o Orca Development Node SMP (threaded) Example
 +
 
 +
ssh orca.sharcnet.ca 
 +
ssh orc-dev1  (or dev2,3,4)
 +
module unload intel openmpi lsdyna
 +
module load lsdyna/smp/r711.88920
 +
lsdyna_d i=airbag.deploy.k ncpu=8
 +
 
 +
==Memory Issues==
 +
 
 +
A minumum of mpp=2G is recommended although the memory requirement of a job may suggest much less is required. For instance setting mpp=1G for the airbag test job above will result in the following error when running a job in the queue:
  
 
<pre>
 
<pre>
−
[roberpj@hnd19:~]  lstc_qrun -help
+
--------------------------------------------------------------------------
−
  o PRINT HELP AND QUIT:                lstc_qrun -help
+
An attempt to set processor affinity has failed - please check to
−
  o PRINT VERSION INFO AND QUIT:        lstc_qrun -v
+
ensure that your system supports such functionality. If so, then
−
  o PRINT SERVER LIST:                  lstc_qrun -i
+
this is probably something that should be reported to the OMPI developers.
−
  o PRINT JOB INFO:                    lstc_qrun [-s server]
+
--------------------------------------------------------------------------
−
  o PRINT LICENSE INFORMATION:          lstc_qrun [-s server] -r
+
−
  o PRINT VERBOSE LICENSE INFORMATION:  lstc_qrun [-s server] -R
+
 
</pre>
 
</pre>
  
−
To check the status of your job in the queue use the sqjobs command.  On x86_64 systems you can check whether any of your jobs are queued on the license server use <i>lstc_qrun</i>.  Its possible that sqsub will start your job but it will sit idle until enough license are available on the license server and the lstc_qrun command will reveal this:
+
Another error message which can occur after a job runs for a while if mpp is chosen to small is:
 +
 
 +
<pre>
 +
>>>>> Process 45 <<<<<
 +
>>>>> Signal 11 : Segmentation Violation <<<<<
 +
</pre>
 +
 
 +
To get an idea of the amount of memory a job used run grep on the output file:
 +
 
 +
<pre>
 +
[roberpj@orc-login1:~/samples/lsdyna/airbag]  cat  ofile.2063302.orc-admin2.orca.sharcnet | grep Memory
 +

 +
 
 +
==Version and Revision==
 +
 
 +
Again run grep on the output file to extract the major and minor revision:
 +
 
 +
<pre>
 +
[roberpj@orc-login1:~/samples/lsdyna/airbag]  cat  ofile.2063302.orc-admin2.orca.sharcnet | grep 'Revision\|Version'

===Running and Queued Programs===
 +
 
 +
To get a summary of running and/or queued jobs use the <i>lstc_qrun</i> command as follows, where queued means the job has started running according to the sqsub command but its actually sitting waiting for license resources to come available.  Once these are acquired the job will start running on the cluster and appear as a Running Program according to  lstc_qrun ie)

===Killling A Program===
 +
 
 +
The queue normally kills lsdyna jobs cleanly.  However its possible that licences for a job (which is no longer running in the queue and therefore no longer has any processes running on the cluster) will continue to be tied up according to the lstc_qrun command.  To kill such a program determine the pid@hostname from the lstc_qrun command then run the following kill command.  The following example demonstrates the procedure for username roberpj:
 +
 
 +
<pre>

LSDYNA
Description: Suite of programs for transient dynamic finite element program
SHARCNET Package information: see LSDYNA software page in web portal
Full list of SHARCNET supported software


Introduction

Before a research group can use LSDYNA on sharcnet, a license must be purchased directly from LSTC for the sharcnet license server. Alternately, if a research group resides at a institution that has sharcnet computing hardware (mac, uwo, guelph, waterloo) it maybe possible to use a pre-existing site license hosted on an accessible institutional license server. To access and use this software you must open a ticket and request to be added to the sharcnet lsdyna group.

Version Selection

Graham Cluster

License

Create and customize this file for your license server, where XXXXX should be replaced with your port number and Y with your server number: 

[roberpj@gra1:~] cat .licenses/ls-dyna.lic 
#LICENSE_TYPE: network
#LICENSE_SERVER: XXXXX@licenseY.uwo.sharcnet

Module

The modules are loaded automatically in the testomp.sh and testmpi.sh script shown below in the example section:

For single node smp jobs the available versions can be found by doing: 

[roberpj@gra-login2:~] module spider ls-dyna
       ls-dyna/7.1.2
       ls-dyna/7.1.3
       ls-dyna/8.1
       ls-dyna/9.1
       ls-dyna/9.2
       ls-dyna/10.0

To load any version do for example: 

module load ls-dyna/9.1

For multi node mpp jobs the available versions can be found by doing: 

[roberpj@gra-login2:~] module spider ls-dyna-mpi
       ls-dyna-mpi/7.1.2
       ls-dyna-mpi/7.1.3
       ls-dyna-mpi/8.1
       ls-dyna-mpi/9.1
       ls-dyna-mpi/9.2
       ls-dyna-mpi/10.0

To load the 7.1.X modules do the following: 

module load openmpi/1.6.5 ls-dyna-mpi/7.1.3

To load the 8.X or 9.X modules do: 

module load openmpi/1.8.8 ls-dyna-mpi/9.2

To load the 10.X modules do: 

module load openmpi/1.10.7 ls-dyna-mpi/10.0

Legacy Clusters

License

Once a license configuration is established, the research group will be given a 5 digit port number. The value should then be inserted into the appropriate departmental export statement before loading the module file as follows:

o UofT Mechanical Engineering Dept 

export LSTC_LICENSE_SERVER=Port@license1.uwo.sharcnet

o McGill Mechanical Engineering Department 

export LSTC_LICENSE_SERVER=Port@license2.uwo.sharcnet

o UW Mechanical and Mechatronics Engineering Dept 

export LSTC_LICENSE_SERVER=Port@license3.uwo.sharcnet

o Laurentian University Bharti School of Engineering 

export LSTC_LICENSE_SERVER=Port@license4.uwo.sharcnet

o Fictitious Example: 

export LSTC_LICENSE_SERVER=12345@license1.uwo.sharcnet

Module

The next step is load the desired sharcnet lsdyna module version. Check which modules are available by running the module avail command then load one the modules as shown: 

[roberpj@orc-login2:~] module avail lsdyna
------------------------------------ /opt/sharcnet/modules ------------------------------------
lsdyna/hyb/r711.88920     lsdyna/mpp/r711.88920     lsdyna/smp/r611.79036
lsdyna/mpp/ls971.r85718   lsdyna/mpp/r712.95028     lsdyna/smp/r711.88920

lsdyna/mpp/r611.80542     lsdyna/smp/ls980B1.78258  lsdyna/smp/r901.109912

r9.0.1 versions

o For serial or threaded jobs: 

module load lsdyna/smp/r901.109912

o For mpi jobs: 

module unload intel openmpi lsdyna mkl
module load intel/15.0.3 openmpi/intel1503-std/1.8.7 lsdyna/mpp/r901.109912

module unload intel openmpi lsdyna mkl
module load intel/15.0.3 openmpi/intel1503-std/1.8.7 lsdyna/mpp/r800.95359

r7.1.2 versions

o For serial or threaded jobs: 

module load lsdyna/smp/r712.95028

o For mpi jobs: 

module unload intel openmpi lsdyna
module load intel/12.1.3 openmpi/intel/1.6.5 lsdyna/mpp/r712.95028

r7.1.1 versions

o For serial or threaded jobs: 

module load lsdyna/smp/r711.88920

o For mpi jobs: 

module load lsdyna/mpp/r711.88920

r6.1.1 versions

o For mpi jobs: 

module unload intel openmpi lsdyna

module load intel/11.1.069 openmpi/intel/1.6.4 lsdyna/mpp/r611.79036
or
module load intel/11.1.069 openmpi/intel/1.6.4 lsdyna/mpp/r611.80542

where r611.80542 provides lsdyna_s only.

ls980 versions

o For serial or threaded jobs: 

module load lsdyna/smp/ls980B1.78258

o For mpi jobs: 

module unload intel openmpi lsdyna

module load intel/12.1.3 openmpi/intel/1.4.5 lsdyna/mpp/ls980B1.011113
or
module load intel/12.1.3 openmpi/intel/1.6.2 lsdyna/smp/ls980B1.78258

Note1) restart capability for ls980smpB1 and ls980mppB1 is not supported Note2) the module using legacy openmpi/intel/1.4.5 will run extremely slow

Job Submission

Graham Cluster

The submission scripts myompjob.sh and mympijob.sh for the airbag problem are shown in the Example Job section below, for both graham and orca. Please note that you should specify your own username if submitting to a def account (not roberpj). Alternatively you could specify your resource allocation account:

Sample threaded job submit script: 

sbatch myompjob.sh

Sample mpi job submit script: 

sbatch  mympijob.sh

Legacy Clusters

When loading a lsdyna sharcnet legacy module on the new orca or a sharcnet legacy system, the single or double precision solvers are specified with lsdyna_s or lsdyna_d respectively, as shown in the following sqsub commands:

1cpu SERIAL Job

sqsub -r 1h -q serial -o ofile.%J --mpp=2G lsdyna_d i=airbag.deploy.k ncpu=1

4cpu SMP Job

sqsub -r 1h -q threaded -n 4 -o ofile.%J --mpp=1G lsdyna_s i=airbag.deploy.k ncpu=4

If using an explicit solver, one can specify a conservative initial memory setting on the command line as follows: 

export LSTC_MEMORY=auto
sqsub -r 1h -q threaded -n 4 -o ofile.%J --mpp=2G lsdyna_d i=airbag.deploy.k ncpu=4 memory=754414

where memory is the minimum number of 8 byte words shared by all processors in double precision, or, 4 byte words in single precision.

The initial value can be determined by starting a simulation interactively on the command line, and finding the output resembling: Memory required to begin solution  : 754414. The number of words can be specified as memory=260M instead of memory=260000000, for further details see https://www.d3view.com/2006/10/a-few-words-on-memory-settings-in-ls-dyna/.

8cpu MPI Job

sqsub -r 1h -q mpi -o ofile.%J -n 8 --mpp=2G lsdyna_d i=airbag.deploy.k

The initial memory can also be specified for mpi jobs on the sqsub command line with "memory=" for the first master processor to decompose the problem and "memory2=" used on all processors including the master to solves the decomposed problem, where the values are specified as 4 bytes per word in single precision and 8 bytes per word in double precision. The number of words can be specified as memory=260M instead of memory=260000000 OR memory2=260M instead of memory2=260000000 for further details see https://www.d3view.com/2006/10/a-few-words-on-memory-settings-in-ls-dyna/. The initial values can be found by running simulation interactively on a orca compute node and checking the output for a line such as: Memory required to begin solution (memory= 464898 memory2= 158794 ) which could then be implemented for a job run in the queue by doing: 

export LSTC_MEMORY=auto
sqsub -r 1h -q mpi -o ofile.%J -n 8 --mpp=2G lsdyna_d i=airbag.deploy.k memory=464898 memory2=158794

The specification of memory2 on sharcnet or compute canada clusters is not beneficial since the queue reserves the same memory per core for all nodes, such that the decomposition master node process cannot be allocated to have larger system memory. Therefore its sufficient to specify a single memory parameter by doing: 

export LSTC_MEMORY=auto 
sqsub -r 1h -q mpi -o ofile.%J -n 8 --mpp=2G lsdyna_d i=airbag.deploy.k memory=464898

where the LSTC_MEMORY variable will only allow the memory to grow for explicit simulations. The following slurm examples demonstrate how to prescribe the memory parameters exactly.

Example Job

Copy the airbag example to your account: 

rsync -av orca.computecanada.ca:/opt/sharcnet/lsdyna/r901.109912/examples r901.109912_examples
cd r901.109912_examples/examples/misc/airbag

New Orca (legacy modules)

Please note, while new orca has most compute canada cvmfs modules available by default it does not have the graham the ls-dyna or ls-dyna-mpi modules installed. Therefore currently the only way to run lsdyna is by using the legacy sharcnet lsdyna modules as shown in the following two smp and mpi examples.

MPI Job

To run the sharcnet legacy module lsdyna/mpp/r712.95028 efficiently over several compute nodes with many cores requires using orca's xeon nodes as shown in mympijob4.sh below. To run lsdyna on orca's opteron nodes with module lsdyna/mpp/r712.95028 requires using only one opteron node as shown in mympijob5.sh below. The other legacy sharcnet lsdyna mpp modules, as shown in the Availability Table lsdyna/mpp/ls971.r85718, lsdyna/mpp/ls980B1.011113, lsdyna/mpp/r611.79036, lsdyna/mpp/r611.80542, lsdyna/mpp/r711.88920, lsdyna/mpp/r800.95359 and lsdyna/mpp/r901.109912 have yet to be tested. If you want to use one but cannot get it working please open a ticket. Note that lines containing a space between "# and SBATCH" are comments. To activate such line(s) required removal of the space ie) "#SBATCH". Its recommended to use module ls-dyna-mpi on graham instead since the machine is far newer, faster and reliable.

Legacy Clusters

STEP1) The following shows sqsub submission of the airbag example to the mpi queue. Its recommended to first edit airbag.deploy.k and change endtim to 3.000E-00 so the job runs long enough to perform the restart in steps 2 and 3 below: 

cp -a /opt/sharcnet/lsdyna/r611.79036/examples /scratch/$USER/test-lsdyna
cd /scratch/$USER/test-lsdyna/misc/airbag
gunzip airbag.deploy.k.gz
cp airbag.deploy.k airbag.deploy.restart.k
nano deploy.restart.k (reduce plot file creation frequency)
   *DATABASE_BINARY_D3PLOT
   $       dt      lcdtdeploy.restart.k
   1.000E-01   <--- change from 5.000E-04 
export LSTC_LICENSE_SERVER=#####@license#.uwo.sharcnet
module unload intel openmpi lsdyna
module load intel/11.1.069 openmpi/intel/1.6.4 lsdyna/mpp/r611.79036
sqsub -r 10m -q mpi --mpp=2G -n 8 -o ofile.%J lsdyna_d i=airbag.deploy.k

STEP2) With the job still running, use the echo command as follows to create a file called "D3KIL" that will trigger generation of restart files at which point the file D3KIL itself will be erased. Do this once a day if data loss is critical to you OR once or twice just before the sqsub -r time limit is reached. Further information can be found here http://www.dynasupport.com/tutorial/ls-dyna-users-guide/sense-switch-control: 

echo "sw3" > D3KIL
sqkill job#

STEP3) Before the job can be restarted, the following two lines must be added to the airbag.deploy.restart.k file: 

*CHANGE_CURVE_DEFINITION
         1

STEP4) Now resubmit the job as follows using "r=" to specify the restart file: 

sqsub -r 1h -q mpi --mpp=2G -n 8 -o ofile.%J lsdyna_d i=airbag.deploy.restart.k r=d3dump01

General Notes

Graham Cluster

There are no special notes at the present time in regards to using lsdyna on graham.


Command Line Use

Following the upgrade of orca to the compute canada module stack, the orca development nodes were discontinued.
Therefore this section is no longer relevent and remain for historical purposes only.

Parallel lsdyna jobs can be run interactively on the command line (outside the queue) for short run testing purposes as follows:

o Orca Development Node MPP (mpi) Example 

ssh orca.sharcnet.ca  
ssh orc-dev1  (or dev2,3,4)
module unload intel openmpi lsdyna
module load intel/12.1.3 openmpi/intel/1.6.2 lsdyna/mpp/r711.88920
mpirun -np 8 lsdyna_d i=airbag.deploy.k

o Orca Development Node SMP (threaded) Example 

ssh orca.sharcnet.ca  
ssh orc-dev1  (or dev2,3,4)
module unload intel openmpi lsdyna
module load lsdyna/smp/r711.88920
lsdyna_d i=airbag.deploy.k ncpu=8

Memory Issues

A minumum of mpp=2G is recommended although the memory requirement of a job may suggest much less is required. For instance setting mpp=1G for the airbag test job above will result in the following error when running a job in the queue: 

--------------------------------------------------------------------------
An attempt to set processor affinity has failed - please check to
ensure that your system supports such functionality. If so, then
this is probably something that should be reported to the OMPI developers.
--------------------------------------------------------------------------

Another error message which can occur after a job runs for a while if mpp is chosen to small is: 

>>>>> Process 45 <<<<<
>>>>> Signal 11 : Segmentation Violation <<<<<

To get an idea of the amount of memory a job used run grep on the output file: 

[roberpj@orc-login1:~/samples/lsdyna/airbag]  cat  ofile.2063302.orc-admin2.orca.sharcnet | grep Memory
     |    Distributed Memory Parallel                  |

 Memory required to complete solution (memory=      458120 memory2=      230721)

Version and Revision

Again run grep on the output file to extract the major and minor revision: 

[roberpj@orc-login1:~/samples/lsdyna/airbag]  cat  ofile.2063302.orc-admin2.orca.sharcnet | grep 'Revision\|Version'
     |  Version : mpp s R6.1.1    Date: 01/02/2013     |
     |  Revision: 78769           Time: 07:43:30       |
     |  SVN Version: 80542                             |

Check License Status

Running and Queued Programs

To get a summary of running and/or queued jobs use the lstc_qrun command as follows, where queued means the job has started running according to the sqsub command but its actually sitting waiting for license resources to come available. Once these are acquired the job will start running on the cluster and appear as a Running Program according to lstc_qrun ie) 

[roberpj@hnd19:~] export LSTC_LICENSE_SERVER=#####@license#.uwo.sharcnet

Killling A Program

The queue normally kills lsdyna jobs cleanly. However its possible that licences for a job (which is no longer running in the queue and therefore no longer has any processes running on the cluster) will continue to be tied up according to the lstc_qrun command. To kill such a program determine the pid@hostname from the lstc_qrun command then run the following kill command. The following example demonstrates the procedure for username roberpj: 

[roberpj@orc-login2:~]  lstc_qrun -R | grep roberpj
roberpj    45312@orc329.orca.shar MPPDYNA          Wed Dec  5 15:50    12

[roberpj@orc-login2:~] lstc_qkill 45312@orc329.orca.sharcnet.ca
Defaulting to server 1 specified by LSTC_LICENSE_SERVER variable
Program queued for termination

[roberpj@orc-login2:~]  lstc_qrun -R | grep roberpj
[roberpj@orc-login2:~]

Legacy Instructions

The following binaries remain available on saw and orca for backward compatibility testing: 

[roberpj@orc-login2:~] cd /opt/sharcnet/local/lsdyna
[roberpj@orc129:/opt/sharcnet/local/lsdyna] ls ls971*
ls971_d_R3_1    ls971_d_R4_2_1  ls971_s_R3_1    ls971_s_R4_2_1  ls971_s_R5_1_1
ls971_d_R4_2_0  ls971_d_R5_0    ls971_s_R4_2_0  ls971_s_R5_0

There are currently no sharcnet modules for these versions, hence jobs should be submitted as follows: 

module load lsdyna
export PATH=/opt/sharcnet/local/lsdyna:$PATH
export LSTC_LICENSE_SERVER=XXXXX@license3.uwo.sharcnet
cp /opt/sharcnet/local/lsdyna/examples/airbag.deploy.k airbag.deploy.k
SERIAL JOB:  sqsub -q serial -r 1d -o ofile.%J ls971_d_R4_2_1 i=airbag.deploy.k
THREADED JOB:  sqsub -q threaded -n 4 -r 1d -o ofile.%J ls971_d_R4_2_1 ncpu=4 para=2 i=airbag.deploy.k

Note! the ls971_s_R3_1 and ls971_d_R3_1 binaries do not work, a fix is being looked for.
