HFSS15: Terminating ANSYS EM LSF Batch Jobs

To cancel or terminate an ANSYS EM LSF batch job, we recommend the use of the LSF bkill command with the -s SIGTERM command line option. Using this option to will allow the Ansoft batch job to shut down in an orderly fashion. Using the LSF bkill command without the -s SIGTERM option or simply terminating the job processes may cause some of the following problems:

• Some engine processes are not shut down, and continue to run

• LSF job is not fully removed

• Project lock file is not removed

• Linux only: MainWin core service processes (watchdog, mwrpcss and/or regss) are not stopped

Some of these may interfere with submission of additional LSF batch jobs. For example, it may be necessary to manually remove the project lock file to submit another batch job for the same project. On Linux, MainWin core service processes may also interfere with starting subsequent Ansoft batch jobs. Normally, these processes should timeout and end 15 seconds after the Ansoft product shuts down. Any MainWin core service processes (watchdog, mwrpcss and/or regss) that continue to run for more than 15 seconds after the product has stopped may be hung. The hung processes may need to be manually killed, after ensuring that these processes are associated with an ANSYS EM job that has finished or terminated.
