Hi, Recently i was testing OMPI in the multi-cluster, heterogeneous environment. Because of the firewall presence between the two test machines i wanted to restrict port used by the OMPI daemons by setting following mca parameters:
oob_tcp_port_min_v4 = 5000 oob_tcp_port_range_v4 = 100 btl_tcp_port_min_v4 = 5000 btl_tcp_port_range_v4 = 100 Unfortunately it didn't work. After looking into source code of the oob and btl tcp components i noticed that the sin_port member was initialized without the conversion from host to network byte order. After adding of the htons call (sample patch attached), the cross-cluster run start working. Regards, -- Mariusz
