USAGE INSTRUCTIONS
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:
Step1 - SPECIFY SHARCNET SERVER
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
Step2 - LOAD LSDYNA MODULE
o For serial or threaded jobs (using ls971 version 6.0.0 or 6.1.0) do:
module load lsdyna/ls971smp6.1.0
o For mpi jobs (using ls971 version 6.0.0 or 6.1.0) do:
module unload intel openmpi lsdyna module load intel/11.1.069 openmpi/intel/1.5.4 lsdyna/ls971mpp6.1.0
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
Step3 - RUN AIRBAG EXAMPLE
To run lsdyna in single precision specify lsdyna_s on the sqsub command line, to run in double precision specify lsdyna_d. The following shows sample sqsub jobs submission for the airbag example http://www.dynaexamples.com/examples-manual/misc/airbag to the serial, threaded and mpi queus on sharcnet.
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
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
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 Defaulting to server 1 specified by LSTC_LICENSE_SERVER variable Running Programs User Host Program Started # procs ----------------------------------------------------------------------------- hsnmoham 12208@orc271.orca.shar MPPDYNA Mon Jan 7 18:17 24 roberpj 9767@hnd15 LS-DYNA_971 Mon Jan 7 19:42 4 No programs queued
CHECKING LICENSE DETAILS
At the time of this writing UWO is running on a 4cpu demo license as follows:

SHOW LSDYNA MODULES
At the time of this writing the following modules were available on orca:
[roberpj@orc-login2:~] module avail lsdyna ---------------- /opt/sharcnet/modules ------------------- lsdyna/ls971mpp6.0.0 lsdyna/ls971smp6.0.0 lsdyna/ls980mppB1 lsdyna/ls971mpp6.1.0 lsdyna/ls971smp6.1.0 lsdyna/ls980smpB1
SUBMITTING JOBS USING LEGACY VERSIONS
The following binaries remain available on saw and orca for backward compatibility testing. There are no sharcnet modules for these versions therefore jobs should be submitted using the steps shown in the next stanza:
[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
To submit a job, the following procedure is recommended:
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.
