Good morning,
im trying to fix this error by myself and i have a little update.
The ompi version i use is the:
Code:
kai@Kai-Desktop:~/Dokumente$ mpirun --version
mpirun (Open MPI) 4.0.3
If i create a *.c file, with the following content:
Code:
#include <mpi.h>
#include <stdio.h>
int main(int argc, char** argv) {
// Initialize the MPI environment
MPI_Init(NULL, NULL);
// Get the number of processes
int world_size;
MPI_Comm_size(MPI_COMM_WORLD, &world_size);
// Get the rank of the process
int world_rank;
MPI_Comm_rank(MPI_COMM_WORLD, &world_rank);
// Get the name of the processor
char processor_name[MPI_MAX_PROCESSOR_NAME];
int name_len;
MPI_Get_processor_name(processor_name, &name_len);
// Print off a hello world message
printf("Hello world from processor %s, rank %d out of %d processors\n",
processor_name, world_rank, world_size);
// Finalize the MPI environment.
MPI_Finalize();
}
After i compile it and execute it:
Code:
kai@Kai-Desktop:~/Dokumente$ mpirun -np 4 ./hello_world -parallel
Hello world from processor Kai-Desktop, rank 0 out of 4 processors
Hello world from processor Kai-Desktop, rank 1 out of 4 processors
Hello world from processor Kai-Desktop, rank 2 out of 4 processors
Hello world from processor Kai-Desktop, rank 3 out of 4 processors
In conclusion mpi works on my computer, or not ?
Why are OpenFoam dosent work with it. ?
Best regards
Kai

Hello,
im trying to ran an Openfoam simulation on multiple cores.
It worked on my system in the past. I didnt consciously changed
anything especially on mpi related things.
The only thing i have changed, i updated my Ubuntu version from 18.04
to 20.04.
As always i trying to execute the following line:
kai@Kai-Desktop:~/OpenFOAM/kai-7/run/tutorials_of/multiphase/interFoam/laminar/damBreak_stl_II/damBreak$
mpirun -np 4 interFoam -parallel
In the past, the simulation started and worked fine. But now this

It looks like MPI_INIT failed for some reason; your parallel process is
likely to abort. There are many reasons that a parallel process can
fail during MPI_INIT; some of which are due to configuration or
environment
problems. This failure appears to be an internal failure; here's some
additional information (which may only be relevant to an Open MPI
developer):
ompi_mpi_init: ompi_rte_init failed
--> Returned "(null)" (-43) instead of "Success" (0)

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: [[32896,1],0]
Exit code: 1
--------------------------------------------------------------------------
I looked into the Systemmonitor, but i didnt have a process with this
name or number.
If i execute
mpirun --version
the consol replys this message:
mpirun (Open MPI) 4.0.3
Report bugs to http://www.open-mpi.org/community/help/
How can I solve this problem ?
