Bonjour, I found this parameter mpool_sm_max_size in this post: http://www.open-mpi.org/community/lists/devel/2008/11/4883.php
But I was unable to spot it back into the 'ompi_info -all' output for v 1.4.3.
Is it still existing ? If not, which other one is replacing it, please ? Also, is it possible to specify to OpenMPI which filesystem to use for the SM backing file, please ? Thanks in advance for any help, Regards, G.
