Dear VTK developers,
we have encountered problems with the MPI InitializeCommunicator calls in VTK 9.3.0 when compiling with the newest Intel compilers (l_HPCKit_p_2024.2.0.635_offline.sh).
The building and installation of VTK worked without errors.
The error appears in the functions this->InitializeCommunicator(vtkMPICommunicator::GetWorldCommunicator()); in line 135 of vtkMPIController.cxx and, respectively, MPI_Comm_set_errhandler(MPI_COMM_WORLD, errhandler); in line 573 of vtkMPICommunicator.cxx.
The result is a complete crash of the program. To reproduce, run test vtkParallelMPICxxTests-MPI No. 1 (MPIController).
We reproduced the problem with various different MPI implementations:
- Stock MPI, installed through
apt, on Ubuntu 22 (Open MPI 4.1.2) - The MPI installation that comes with the intel compilers (Intel(R) MPI Library for Linux* OS, Version 2021.13 Build 20240515 (id: df72937))
- Standalone compilation of Open MPI using the Intel OneAPI compilers (Open MPI 4.0.4)
When compiling using GNU compilers (gcc 12.3.0 + Open MPI 4.1.2 (apt)), everything works fine.
Attached is a excerpt of the CMakeCache.txt, from when we tried to compile with Open MPI 4.0.4, if that is of any help:

Any help is appreciated.
Thanks a lot in advance.
