 Hi Erik,

 Yes and sorry. To clarify, this is the script I used for which the NaNs
 appeared. The admin would've used a different script for looking at the
 traffic. If you like, I can ask for it.

 "nodes=1:ppn=44" means "use 1 node, run 44 processes on that node." Is
 that intended? If so, there would be no Infiniband traffic generated.
