Hi,
I have observed that when trying to trace the following program with mpiexec -trace everything work fine
as long as I stick with "use mpi". If I change that to "use mpi_f08" I do not get a tracefile.
The reason I'm interested in using mpi_f08 is because I have an application to trace that uses
the shared memory MPI model and it seems that the call to
MPI_Comm_split_type
that is used below is only possible with the mpi_f08 module, right?
Any hints on why I cannot trace that program when using "use mpi_f08"?
Some extra Info:
$ mpiifort -o shm shm.f90
$ mpiifort --version
