Sometime before I have posted doubts about using dual gigabit support
fully. See I get ~140MB/s full duplex transfer rate in each of following
mpirun --mca btl_tcp_if_include eth0 -n 4 -bynode -hostfile host a.out
mpirun --mca btl_tcp_if_include eth1 -n 4 -bynode -hostfile host a.out
How to combine these two port or use a proper routing table in place host
file? I am using openmpi-1.1 version.
