Thank you Hal & Joe for your prompt reply. Two more questions: If ifconfig for IB is just for IPoIB, is it okay to bring down this interface(ib0) and still be able to run applications like Mvapich2 and pvfs2 ??
And I also assume that we At Least Need 1 Ethernet Interface Up for the correct operation of IB compiled Applications, without which IB compiled Applications will fail. Is this correct ??
