Hi,
I was trying to understand how "btl_openib_use_message_coalescing" is working.

"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-le

24core cpus.
So total number of processes that I am running is 8*24=192. In summary,
alltoall test on 8nodes and 24 processes per node.
But, my test consumes all RAM and swap space memory. However, if I count

Your calculation looks correct, the conclusion is slightly wrong
however. The Application buffers
some other
environment variables ? or anything like that ?
