Abaqus/en: Difference between revisions

Below are proto-type slurm scripts for submitting thread and mpi based parallel simulations to single or multiple compute nodes.  Most users will find it sufficient to use one of the <i>work directory </i> scripts provided in the Single Compute Node sections. The optional "memory=" argument found in the last line of the scripts is intended for larger memory or problematic jobs where 3072MB offset value may require tuning.  A listing of all abaqus command line arguments can be obtained by loading an abaqus module and running: <code>abaqus -help | less</code>.  For Single Node jobs that run less than a day the <i>work directory script</i> with restart file writing disabled should be sufficient. Single node jobs that will run for more than a day should however write restart files.  Jobs that create large restart files will benefit by writing to local disc through the use of the SLURM_TMPDIR environment variable utilized in the <i>tmp directory scripts</i> provided in the two rightmost tabs of the Single Node standard and explicit analysis sections.  The restart scripts shown here will continue jobs that have been terminated early for some reason.  Such job failures can occur if a job reaches its maximum requested runtime before completing and is killed by the queue or if the compute node the job was running on crashed due to an unexpected hardware failure.  Other restart types are possible by further tailoring of the input file (not shown here) to continue a job with additional steps or change the analysis (see the documentation for version specific details).  Jobs that require large memory or larger compute resources (beyond that which a single compute node can provide) should use the mpi scripts in the Multiple Node sections below to distribute computing over arbitrary node ranges determined automatically by the schedular.  Short scaling test jobs should be run to determine wall clock times (and memory requirements) as a function of the number of cores (2, 4, 8, etc) to determine the optimal number before running any long jobs.
