Re^3: Initializing global P2P interface... init 3 failed

Alex Granovsky

Dear Anton,

P2P interface can be sensitive to TCP/IP misconfiguration.

try to add the following to your input:

$p2p net=C0A80C00 mask=FFFFFF00 $end

Hope this helps.

As P2P works directly through TCP/IP rather than MPI,
OpenMPI parameters you tried to use do not affect
P2P-related errors.

Kind regards,
Alex Granovsky
