[mvapich-discuss] Problem in running mpi processes on TCP/IP

[Devesh Sharma]

Hello Matthew,

Thanks for replying, This I have alredy tried but I dont see and data
traffic on ib0 interface (visual indication is LED blinking), event I run
Pallas
after boting mpd in the same way!

secondly on starting node (for mpd) mdptrace -l shows IP of ibnode1 and IP
on node2 and vice versa for other node
what is the reason?
