Note on the docker container output #1213

Closed germa89 closed 2 years ago

germa89 commented 2 years ago

Hi

While running v21.2.0 in GitHub Actions (as a service), I saw the following note:

 **********************************************************************************
 NOTE: Error occurred while setting the thread affinity on Linux.  Error code = 22.
 **********************************************************************************

I wonder if it is relevant or not.

Notes

Pinging @akaszynski @FredAns @koubaa @dts12263 for visibility.

@germa89 Try setting the environment variable KMP_AFFINITY=disabled prior to launching MAPDL. Mike

Hi @mikerife

Thank you for your answer. Is there any reason for that note though? It might be a good trade off for something.

Regards

mikerife commented 2 years ago

Hi @germa89 Just prior SRs on that error message. Have run into this oh once a year or so. It used to, v18.0, cause MAPDL to fatal error exit. So my first reaction is to just disable and go from there.

Hi @mikerife

Thank you for the info. It seems it is a way to cluster threads: https://cvw.cac.cornell.edu/hybrid/kmpaffinity

I think I am going to disable it

mikerife commented 2 years ago

HI @germa89 yes it is; normally we leave it to the job scheduler to set any needed thread-core pairing/ordering.

germa89 commented 2 years ago

We should probably link this info to here:

https://dev.docs.ansys.com/contents/ansys_best_practices/containers/mpi_containers.html

Although I know it's different issue...
