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)?
