Hi, I was not the one updating the machine unfortunately, however I can ask my colleagues for specific list of modifications done. If I understand you correctly you are referring to the "ulimit" parameters. They are properly set, in fact we use JMS as job scheduler, therefore the "ulimit -v" is set by the user. In my case I used 31GB per MPI process. The stack size is set to infinity.

What was updated? If the OS, did you remember to set the memory registration limits to max?

Since a recent update of our machine I started generating mpi errors. The code crashes after completing approx. 24 % from the total job. The same code and input were run before on the same machine and no such problems were ever observed. The actual error message is attached. I presume that after the update an incompatibility between the infiniband-stack and the openmpi library might have been introduced. I think that the suggested "out of memory problem" should not be causing the malfunction, since the application uses only 1GB of the total 32 GB available. I would appreciate your help and ideas how to clarify this issue.
