Victor,
If the MX library supports a mapper, Open MPI takes provide selective hardware
activation. Look at the MCA parameters supported by the MX devices to get more
info (ompi_info —mca btl mx). The one that is of interest in this particular
case is mx_if_include, allowing MX based jobs to onl
Victor -
I don't think our multi-port support with MX is particularly well tested (I
know I don't test that path).
It looks like you might be able to work around the problem by setting -mca
mtl_mx_endpoint_num 1 on the mpirun command line, which will only use the first
port found. But I could
Good evening
A quick question,
If I set the short message size limit to an unreasonably large number as
below, will this request be honored by OpenMPI
mpirun --mca btl tcp,self \
--mca btl_tcp_eager_limit 2097152 \
--mca btl_tcp_rndv_eager_limit 2097152 \
--mca bt
