R help - Sep 2022 - Install Rmpi on Linux on a HPC

Hi,

Recently, I have had a hard time installing and running the package on an
HPC.

The HPC sysadmin installed Rmpi package without any error.

However, when he tried a simple R script with only one line:
 library(Rmpi)
the job caused "Segmentation Fault" error.

Currently, we have no clue to solve this problem. I am writing this
email to ask for help.

System info
uname -a
Linux ito-1 3.10.0-514.26.2.el7.x86_64 #1 SMP Fri Jun 30 05:26:04 UTC 2017
x86_64 x86_64 x86_64 GNU/Linux

Thank you

Best regards

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
debugging symbols.

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.
