Due to the way our Fluent and ANSYS modules are configured, simultaneously loading multiple of either module will cause a cryptic error. The most common case of this happening is when multiple of a users jobs are started at the same time and all load the module at once. In order for this error to manifest, the modules have to be loaded at precisely the same time; a rare occurrence, but a probable occurrence over the long term.
If you encounter this error you are not at fault. Please resubmit the failed job(s).
If you frequently submit large amounts of Fluent or ANSYS jobs, we recommend you stagger your job submit times to lower the chances of two jobs starting at the same time, and hence loading the module at the same time. Another solution is to establish job dependencies between jobs, so jobs will only start one after another. To do this, you would add the PBS directive:
#PBS -W after:jobid
To jobs you want to only start after another job has started. You would replace
jobid with the job ID of the job to wait for.
If you have additional questions, please contact OSC Help at OSCHelp@osc.edu.
