Rolf,

From the man page of MPI_Win_allocate_shared

It is the user's responsibility to ensure that the communicator comm represents a group of processes that can create a shared memory segment that can be accessed by all processes in the group

And from the mtt logs, you are running 4 tasks on 2 nodes.

Unless I am missing something obvious, I will update the test tomorrow and add a comm split to ensure MPI_Win_allocate_shared is called from single node communicator and skip the test if this impossible

Cheers,

Gilles

On both 1.8 and trunk (as Ralph mentioned in meeting) we are seeing three tests fail.

Ibm/onesided/win_allocated_shared_mpifh
Ibm/onesided/win_allocated_shared_usempi

Is there a ticket that covers these failures?

Thanks,
