When using mpirun, how do you pick which ports are used?
I???ve tried:
mpirun --mca btl_tcp_port_min_v4 46207 --mca btl_tcp_port_range_v4 32 --mca
oob_tcp_keepalive_time 45 --mca oob_tcp_max_recon_attempts 20 --mca
oob_tcp_retry_delay 1 --mca oob_tcp_keepalive_probes 20 --mca
oob_tcp_keepalive_intvl 10 true
And also setting similar things in openmpi/etc/openmpi-mca-params.conf :
btl_tcp_port_min_v4 = 46207
btl_tcp_port_range_v4 = 32
oob_tcp_keepalive_time = 45
oob_tcp_max_recon_attempts = 20
oob_tcp_retry_delay = 1
oob_tcp_keepalive_probes = 20
oob_tcp_keepalive_intvl = 10
But when the process is running:
ss -l -p -n | grep "pid=57642,"
tcp LISTEN 0 128 127.0.0.1:58439
0.0.0.0:* users:(("mpirun",pid=57642,fd=14))
tcp LISTEN 0 128 0.0.0.0:36253
0.0.0.0:* users:(("mpirun",pid=57642,fd=17))
What am I doing wrong, and how do I get it to use my desired ports (and other
settings above)?
Hello
Could this be related to some recently resolved bug ?
What version are you running ?
Having a look on https://github.com/open-mpi/ompi/issues/8304 could be
possibly useful?

Vincent.
