Siegmar,
I was able to reproduce the issue on my vm
(No need for a real heterogeneous cluster here)
I will keep digging tomorrow.
Note that if you specify an incorrect slot list, MPI_Comm_spawn fails with a
very unfriendly error message.
Right now, the 4th spawn'ed task crashes, so this is a dif
Hi Gilles,
thank you very much for your help. What does incorrect slot list
mean? My machine has two 6-core processors so that I specified
"--slot-list 0:0-5,1:0-5". Does incorrect mean that it isn't
allowed to specify more slots than available, to specify fewer
slots than available, or to specif
Siegmar,
Your slot list is correct.
An invalid slot list for your node would be 0:1-7,1:0-7
/* and since the test requires only 5 tasks, that could even work with such
an invalid list.
My vm is single socket with 4 cores, so a 0:0-4 slot list results in an
unfriendly pmix error */
Bottom line, y
Hi,
I have an directory in /opt/openshmem which contains software from
mellanox. Should I specify during OMPI installation (at the configure
step) where that directory is located? If yes, how? I have been looking
for a "--with-oshmem=" but haven't found anything, as for instance
other Mellano
Juan,
Open MPI has its own implementation of OpenSHMEM.
The Mellanox software is very likely yet an other implementation of
OpenSHMEM.
So you can consider these as independent libraries
Cheers,
Gilles

Hi Gilles,
does it mean I should ignore it and run configure script without
specifying anything about OpenSHMEM?
From other hand, my cluster has Mellanox OFED, but the knem libraries
are not installed from the MXM OFED software. Instead, it was installed
from the original knem website. Shou
