We build and support the HPC cluster infrastructure for the business as per their requirements. I have reached out to you to get help on an issue that we are currently facing with MPI. It would be great if you could help us in getting a solution to it. Nonmem is the application in which users submit the jobs through CLI, it is a CLI based application. When user tries to run job with more no. of cores the job runs for 10 to 15 hours and then stops intermittently. Please find the below error message that we get in our output file. 1.
