Re^3: Firefly MPICH version statically linked: performance degradation using multiple nodes.

Hi,

most often, p2p init failures are caused either by
network mis-configuration problems on some nodes,
or by significant differences in network configuration
across nodes. These problems can be easily solved using
advanced p2p options. However, it is necessary to look
at your network setup. I'd ask you to attach "ifconfig -a"
output on the nodes you are trying to run Firefly with
p2p turned on, to this thread.  

Regards,
Alex Granovsky
