Hi,
I have successfully built openmpi-3.0.0 from source with cuda 8.0.61.2 and
7.5.18 on CentOS-7 x86_64 (default system gnu compilers).
I am trying to build openmpi-3.0.0 with cuda9 on CentOS-7 and failed
with cuda9 with this error:
make[2]: Leaving directory
`/c7/home/tru/build/openmpi-3.0.0/b
my cluster nodes are connected on 1g ethernet eth0/eth1 and via
infiniband rdma and ib0
my understanding is that openmpi will detect all these interfaces.
using eth0/eth1 for connection setup and use rdma for msg passing
what would be an appropriate to command line parameters to tell
openmpi to i
mpirun --mca oob_tcp_if_include ib0 --mca oob tcp ...
Note that if your cluster is large and ARP tables are not fully populated,
IPoIB might not be the best idea.
Cheers,
Gilles

What is the IB stack used, just RHEL inbox?
Do you run openmpi on the psm mtl for qlogic and openib btl for
mellanox or some
Hello everyone,
I am trying to debug through the MPI functionality at our local clusters. I
use openmpi 3.0 and the executable were compiled by PGI 10.9. The
executable is a regional air quality model called "CAMx" which is widely
used in our community. In our local clusters setting, I have a clus
