Hello!
I am using Open MPI v1.8.1 in
example program hello_oshmem.cpp.
When I put spml_ikrit_np = 1000 (more than 4) and run task on 4 (2,1) nodes, I
get an:
in out file:
No available spml components were found!
This means that there are no components of this type installed on your

Hello!
I have open mpi 1.9a1r32104 and open mpi 1.5.5.
I have much better perfomance in open mpi 1.5.5 with openMP on 8 cores
in the program:

int main(int argc, char *argv[]) {
...
MPI_Init(&argc, &argv);
...
for (i = 0; i < N; i++) {
a[i] = i * 1.

I have the same problem in openmpi 1.8.1( Apr 23, 2014 ).
Does the srun command have a --map-by mpirun parameter, or can i chage it
from bash enviroment?
