There's a known bug in tcsh/csh that causes forked file descriptors to not be correctly propagated. Can you use a more modern shell if you are using one of those? -- Pavan

Hello,
I am an undergraduate student. I have never worked with MPI and I have to use the Einstein Toolkit code which uses MPI for my project. I am running it on my personal laptop, it has two cores and four threads.
I get this error in my simulation:
Fatal error in PMPI_Comm_rank: Invalid communicator, error stack: PMPI_Comm_rank(110): MPI_Comm_rank(comm=0x57ed58e0, rank=0x7ffe6cb18148) failed PMPI_Comm_rank(68).: Invalid communicator [unset]: write_line error; fd=-1 buf=:cmd=abort exitcode=609541 : system msg for write_line failure : Bad file descriptor ------------------------------------------------------- Primary job terminated normally, but 1 process returned a non-zero exit code.. Per user-direction, the job has been aborted. ------------------------------------------------------- -------------------------------------------------------------------------- mpirun detected that one or more processes exited with non-zero status, thus causing the job to be terminated. The first process to do so was:
Process name: [[32146,1],0] Exit code: 5 --------------------------------------------------------------------------
Please let me know what the problem is and how to solve it.
