Jayanta,
What is your bus on this machine? If it is PCI-X 133 you are going to be
limited, also memory bandwidth could also be the bottleneck.
Thanks,
Galen

Hi,
In between two nodes I have dual Gigabit ethernet full duplex links. I was
doing benchmarking using non-blocking MPI send and receive. But I am
getting only speed corresponds to one Gigabit ethernet full duplex link
(< 2Gbps). I have checked using ifconfig, this transfer is using both the
ports, then why I am not getting full throughput from dual Gigabit
ethernet ports? Can anyone please help me in this?
Regards,
Jayanta
