Introduction
to LS-DYNA3D
To break jobs into 48 CPU hour chunks:
1) Using C=cpu [cpu limit in seconds] defines the maximum cpu usage
allowed that if exceeded will cause LS-DYNA to terminate with a restart file.
Note that 48 hours is 172800 seconds.
2) During a restart, cpu should be set to the total cpu used up to the
current restart plus whatever amount of additional time is wanted.
3) Use R=rtf where rtf is the restart filename when restarting.
4) Use qsub -W
depend=after:<JobID> on the second job where <JobID> is the
Job ID of the first job.
☞Note: DYNA_SCRDIR is
required!

example
Differences from apollo/artemis script are bold
Replace Y where Y is the number of
nodes
#!/bin/csh
#PBS -q para -l nodes=Y:notusall:ppn=2
setenv MY_DIR "/user/jmatrow/LS-DYNA/forming/2procs"
setenv DYNA_SCRDIR "/temp/jmatrow/$PBS_JOBNAME.$PBS_JOBID"
setenv DYNA_ARGS "i=forming.k" #<---REQUIRED!
mkdir
$DYNA_SCRDIR
cp $MY_DIR/forming.k $DYNA_SCRDIR
cp $MY_DIR/model.key $DYNA_SCRDIR
source /apps/LS-dyna/run_dyna.csh
cp $DYNA_SCRDIR/d3plot* $MY_DIR
cd; rm -rf $DYNA_SCRDIR
^ ^ ^ ^
^ This is using mpp970 and it is not working right now
v v v v
v Use ls970 example below and only 1 node (2 processors)
#!/bin/csh
#PBS -q para -l nodes=1:notusall:ppn=2
setenv MY_DIR "/user/jmatrow/LS-DYNA/forming/2procs"
setenv DYNA_SCRDIR "/temp/jmatrow/$PBS_JOBNAME.$PBS_JOBID"
mkdir $DYNA_SCRDIR
cp $MY_DIR/forming.k $DYNA_SCRDIR
cp $MY_DIR/model.key $DYNA_SCRDIR
cd $DYNA_SCRDIR
setenv LSTC_FILE /apps/LS-dyna/LSTC_FILE.txt
ls970 i=forming.k ncpu=-2
cp $DYNA_SCRDIR/d3plot* $MY_DIR
cd; rm -rf $DYNA_SCRDIR
zeus
example
Replace X where X is the number of processors
#!/bin/csh
#PBS -q para -l host=zeus -l ncpus=X #<---Notice change from nodes= to
host=
setenv MY_DIR "/user/jmatrow/LS-DYNA/forming/2procs"
setenv DYNA_SCRDIR "/temp/jmatrow/$PBS_JOBNAME.$PBS_JOBID"
mkdir $DYNA_SCRDIR
cp $MY_DIR/forming.k $DYNA_SCRDIR
cp $MY_DIR/model.key $DYNA_SCRDIR
cd $DYNA_SCRDIR
setenv LSTC_FILE /apps/LS-dyna/LSTC_FILE.txt
ls960 i=forming.k memory=120000000 ncpu=-X
cp $DYNA_SCRDIR/d3plot* $MY_DIR
cd; rm -rf $DYNA_SCRDIR
You may substitute ls970 for ls960 if needed
apollo/artemis
example
Replace X and Y where X is the number of
processors and Y is X divided by 2
#!/bin/csh
#PBS -q para -l nodes=Y:ia32:ppn=2
setenv MY_DIR "/user/jmatrow/LS-DYNA/forming/2procs"
setenv DYNA_SCRDIR "/temp/jmatrow/$PBS_JOBNAME.$PBS_JOBID"
mkdir $DYNA_SCRDIR
cp $MY_DIR/forming.k $DYNA_SCRDIR
cp $MY_DIR/model.key $DYNA_SCRDIR
cd $DYNA_SCRDIR
setenv LSTC_FILE /apps/LS-dyna/LSTC_FILE.txt
set path = (/opt/mpich/bin $path) #<---Notice
correction from $PATH to $path!
mpirun -np X /apps/LS-dyna/mpp970 i=forming.k memory=120000000
cp $DYNA_SCRDIR/d3plot* $MY_DIR
cd; rm -rf $DYNA_SCRDIR
You may substitute mpp960 for mpp970 if
needed
Contact me if you *have* to use single processor ls960
