I am getting an internal compiler error using ifort. Version information:

Well, an internal compiler error is always a compiler error. So the best thing is to provide a so called minimal reproducer, i.e. a code example as small as possible and still big enough to trigger to ICE and submit it to the official Intel support. Until the issue gets fixed, it might be much harder to find a workaround. Apparently your code is a hybrid OpenMP and MPI code, which doesn't make it any easier.
This issue is better to be reported via our Online Service Center at https://supporttickets.intel.com/ for further investigation.
