USAGE INSTRUCTIONS (sharcnet installation)
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. Insert the value into the appropriate departmental export statement shown below (before loading the module file) as shown in the following two steps:
Step1 - SPECIFY SHARCNET SERVER
o Demo License All Users (Jan20 to Feb20)
export LSTC_LICENSE_SERVER=31052@license1.uwo.sharcnet
o UW Mechanical and Mechatronics Engineering Dept (UW Sharcnet Systems)
export LSTC_LICENSE_SERVER=UW_Port_Number@db.uwo.sharcnet
o UWO Civil and Environmental Engineering Dept (UWO Sharcnet Systems)
export LSTC_LICENSE_SERVER=UWO_Port_Number@license1.uwo.sharcnet
Step2 - LOAD LSDYNA MODULE
module load lsdyna
RUNNING A TEST EXAMPLE
cp -a /opt/sharcnet/lsdyna/ls971dR5.0/examples /scratch/$USER/examples-lsdyna cd /scratch/$USER/examples-lsdyna/load/generalized gunzip load_body.shell.k.gz
o SUBMIT 1CPU SERIAL JOB (double precision)
sqsub -t -q serial -r 10m -o ofile1cpu.%J lsdyna_d ncpu=1 i=load_body.shell.k
o SUBMIT 4CPU THREADED TEST JOB (single precision)
sqsub -t -q threaded -n 4 -r 5m -o ofile4cpu.%J lsdyna_s ncpu=4 para=2 i=load_body.shell.k
o SUBMIT 4CPU PARALLEL (MPP) TEST JOB
Support for mpi (MPP) based lsdyna jobs is presently under construction. Once its ready a sample sqsub command line will be posted here - expected by Feb 10 2012.
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:
[jole@saw:~] lstc_qrun
Defaulting to server 1 specified by LSTC_LICENSE_SERVER variable

AVAILABLE BINARY VERSIONS
In the previous example, the latest lsdyna versions were specifed using simply lsdyna_s for single precision and lsdyna_d for double precision. One can alternatively specify any of the following binary names explicty on x86_64 systems assuming your license allows there use:
ls971_s_R3_1 ls971_d_R3_1 ls971_s_R4_2_1 ls971_d_R4_2_1 lsdyna_d = ls971_d_R5_0 --> ls971_d_R5_0_intel64_redhat54 lsdyna_s = ls971_s_R5_0 --> ls971_s_R5_0_intel64_redhat54
GETTING HELP
If you experience problems submitting or running jobs please submit a ticket to the web portal and it will be resolved asap by clicking here [1]. Specify software as the category and paste any error messages and provide effected job number(s).
USAGE INSTRUCTIONS (uw local installation)
These instructions apply to the script driven (non-modularized) site local installation of lsdyna found under /opt/sharcnet/local/lsdyna on orca and saw. To use this software you must be a member of the uw_lsdyna group and follow the below usage instructions.
o Set up LS-Dyna environment
add the following 4 lines to the end of your .bash_profile file in your /home directory, where the port number 3XXXX should be set to override the 31010 default.
#Env. for LS-Dyna export LSTC_LICENSE=network export LSTC_LICENSE_SERVER="3XXXX@db.uwo.sharcnet" export PATH=/opt/sharcnet/local/lsdyna:$PATH
o RUN 1CPU SERIAL JOB from your file (input file) directory on saw or whale
sqsub -q serial -r 3.0d -o airbag.out ls971_s_R3_1 i=airbag.deploy.k
O RUN 4CPU SMP JOB
sqsub -q threaded -n 4 -r 3.0d -o -o airbag.out ls971_s_R3_1 ncpu=4 para=2 i=airbag.deploy.k
A more detailed info and usage suggestions can be found in a file named 'README_uw_lsdyna' in /home/jemmyhu/tests/test_lsdyna on SHARCNET systems.
