Is there a job submission system on the HPC that is required for
programs that need MPI? Does the error still happen if you use it,
sacrificing the ability to run R with Rmpi interactively?
Do you have a debugger (probably gdb) available to you? Debugging
segmentation faults without a debugger is, in theory, possible, but
requires a lot of experience and effort. We'll need at least a
backtrace in order to start debugging, and for that we'll need the
What does the HPC sysadmin say about this problem? You'll probably have
to contact this person anyway in order to get access to a debugger and
ensure that the debugging symbols are available.
