Yalla works because MXM defaults to using unconnected datagrams (I don’t think
it uses RC unless you ask). Is this a fully connected algorithm? I ask because
(3584 - 28) * 28 * 3 (default number of QPs/remote process in btl/openib) =
298704 > 262144. This is the problem with RC. Mellanox solved
Hi,
One of our users is having trouble scaling his code up to 3584 cores (i.e. 128
28-core nodes). It runs fine on 1792 cores (64 nodes), but fails with this at
3584:

questions have already been answered.
Thanks.

Cheers,
Gilles

Hi,
I'm having a strange issue with Openmpi-1.4.
Whenever I try to run a program with number of mpi more than 1, it crashes.
For instance the following code:
mpirun -np 2 -bynode `which relion_refine_mpi` --gpu --tau2_fudge 2
--scale --dont_combine_weights_via_disc --iter 25 --norm --psi_ste
