After writing some tests, I discovered Open MPI's MPI_Get_address()
fails if fed with MPI_BOTTOM. Is this on purpose of just an error
checking oversight?
$ cat get_address.c
#include <mpi.h>
int main(int argc, char *argv[])
{
MPI_Aint addr;
MPI_Init(&argc, &argv);
MPI_Get_address(MPI_BOTTOM, &addr);
MPI_Finalize();
return 0;
}
$ mpicc get_address.c
$ ./a.out
[kw2060:18815] *** An error occurred in MPI_Get_address
[kw2060:18815] *** reported by process [140737192329217,140655883976704]
[kw2060:18815] *** on communicator MPI_COMM_WORLD

[kw2060:18815] *** MPI_ERRORS_ARE_FATAL (processes in this
communicator will now abort,
[kw2060:18815] *** and potentially your MPI job)
