I actually have a use case where my library will attach many
non-overlapping vm segments on demand to a single dynamic OMPI_Win_t
object. With the current static limit, I would either have to increase it
optimistically before startup or maintain a pool of dynamic win objects.
However, other MPI imp
Hi Gilles, thank you so much once again!
I have a success using directly the psm2 mtl. Indeed, I do not need to use the
cm pml (I guess this might be because the cm pml gets automatically selected
when I enforce the psm2 mtl?). So both the following two commands execute
successfully with Open M

Eduardo,
You have two options to use OmniPath
- “directly” via the psm2 mtl
mpirun —mca pml cm —mca mtl psm2 ...
- “indirectly” via libfabric
mpirun —mca pml cm —mca mtl ofi ...
I do invite you to try both. By explicitly requesting the mtl you will
avoid potential conflicts.
libfabric is used

Hi Gilles, thank you so much for your support!
For now I'm just testing the software, so it's running on a single node.
Your suggestion was very precise. In fact, choosing the ob1 component leads to
a successfull execution! The tcp component had no effect.
mpirun --mca pml ob1 —mca btl tcp,self
Jeff,
At first glance, a comment in the code suggests the rationale is to minimize
the number of allocations and hence the time spent registering the memory.
Cheers,
Gilles
