Introduction

Researchers who want to use LSDYNA must either purchase a license for the sharcnet license server OR have both sharcnet computing hardware at their local institution (mac, uwo, guelph, waterloo) and an accessible institutional license server.

Usage

These usage instructions apply to the module based installation of lsdyna found under directory /opt/sharcnet/lsdyna on licensed clusters shown in the above Availability Table. To access and use this software you must be a member of the lsdyna 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:

o UWO Civil and Environmental Engineering Dept

export LSTC_LICENSE_SERVER='PortNumber'@license1.uwo.sharcnet

o McGill Mechanical Engineering Department

export LSTC_LICENSE_SERVER='PortNumber'@license2.uwo.sharcnet

o UW Mechanical and Mechatronics Engineering Dept

export LSTC_LICENSE_SERVER='PortNumber'@license3.uwo.sharcnet

Module Selection

[roberpj@orc-login1:~] module avail lsdyna
 
-------------------------------------- /opt/sharcnet/modules ---------------------------------------
lsdyna/ls971mpp6.0.0 lsdyna/ls971mpp6.1.1 lsdyna/ls971smp6.1.0 lsdyna/ls980mppB1
lsdyna/ls971mpp6.1.0 lsdyna/ls971smp6.0.0 lsdyna/ls971smp6.1.1 lsdyna/ls980smpB1

o For serial or threaded jobs (using ls971 version 6.0.0 or 6.1.0 or 6.1.1) do:

module load lsdyna/ls971smp6.1.1

o For mpi jobs (using ls971 version 6.0.0 or 6.1.0 or 6.1.1) do:

module unload intel openmpi lsdyna
module load intel/11.1.069 openmpi/intel/1.5.4 lsdyna/ls971mpp6.1.1

o For serial or threaded jobs (using version ls980) do:

module load lsdyna/ls980smpB1

o For mpi jobs (using version ls980) do:

module unload intel openmpi lsdyna
module load intel/12.1.3 openmpi/intel/1.4.5 lsdyna/ls980mppB1

Job Submission

To run the single or double precision solvers specify lsdyna_s or lsdyna_d respectively:

o SUBMIT 1CPU SERIAL JOB

sqsub -r 7d -q serial -o ofile.%J --mpp=2G lsdyna_d i=airbag.deploy.k ncpu=1 

o SUBMIT 4CPU SMP JOB

sqsub -r 7d -q threaded -n 4 -o ofile.%J --mpp=2G lsdyna_d i=airbag.deploy.k ncpu=4

o SUBMIT 4CPU MPI JOB

sqsub -r 7d -q mpi -n 4 -o ofile.%J --mpp=1G lsdyna_d i=airbag.deploy.k

Example Job

STEP1) The following shows a sample sqsub jobs submission for the airbag example http://www.dynaexamples.com/examples-manual/misc/airbag to the mpi queus on sharcnet followed by the echo command to trigger restart files to be generated, followed by killing off the job:

cp -a /opt/sharcnet/lsdyna/ls971smp6.1.0/examples /work/$USER/test-lsdyna
cd /work/$USER/test-lsdyna/misc/airbag
gunzip airbag.deploy.k.gz
sqsub -r 1h -q mpi --mpp=4G -n 8 -o ofile.%J lsdyna_d i=airbag.deploy.k
echo "sw3" > D3KIL
sqkill all

STEP2) Note the job can be restarted using the following sqsub command once the following two lines to the k file airbag.deploy.restart.k file:

• CHANGE_CURVE_DEFINITION

        1

sqsub -r 1h -q mpi --mpp=4G -n 8 -o ofile.%J lsdyna_d i=airbag.deploy.restart.k r=d3dump01

General Notes

Checking Job Status

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 lstc_qrun. 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:

[roberpj@hnd19:~/samples/lsdyna] lstc_qrun

Checking License Details

At the time of this writing UWO is running on a 4cpu demo license as follows:

[roberpj@hnd19:~/samples/lsdyna]  lstc_qrun -R

Submitting Jobs Using Legacy Versions

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.
