Hi,
I am setting up version 1.7.2 for a Cray XE-6. The build nodes have
different interfaces than the compute nodes. I have been able to set it
up, but users need to embed the following into their mpirun command:
--mca btl_tcp_if_include ipogif0
Currently, The ompi_info shows as below. I have been trying to figure
out the correct configure switch to add to the build to remove the need
for a permanent mpirun switch, but seem to be not getting it right. Any
suggestions are welcomed. Thanks,
Ray
ompi_info --param btl all
MCA btl: parameter "btl_tcp_if_include" (current
value: "",
data source: default, level: 1 user/basic, type:
string)
Comma-delimited list of devices and/or CIDR
notation of networks to use for MPI communication
(e.g., "eth0,192.168.0.0/16"). Mutually
exclusive
with btl_tcp_if_exclude.
MCA btl: parameter "btl_tcp_if_exclude" (current value:
"127.0.0.1/8,sppp", data source: default,
level: 1
user/basic, type: string)
Comma-delimited list of devices and/or CIDR
notation of networks to NOT use for MPI
communication -- all devices not matching these
specifications will be used (e.g.,
"eth0,192.168.0.0/16"). If set to a non-default
value, it is mutually exclusive with
btl_tcp_if_include.
