I was trying to understand how "btl_openib_use_message_coalescing" is working.
Since for a certain test scenario, IMB-EXT is working if I use "btl_openib_use_message_coalescing = 0" and not for "btl_openib_use_message_coalescing = 1"
No idea, who can have BUG here either open-mpi or low-level-driver !! ??
Howsoever, I have one more concern as well. I added some prints to debug openmpi.
I was following below procedure,
Extract OFED TAR
Go to SOURCE
But, it was taking whole lot of my time. Is there any short cut ?
