[Yutaka Kubota]

Dear MVAPICH2 Discuss team,

This is Yutaka Kubota from Cray Japan.

We have executed LS-DYNA and topcrunch data with MVAPICH2 environment. However This job is always hung up on "3 cars collision" of topcrunch that is over 256 cores and 2 or 4 rails.

Could you investigate about this symptom?
I am waiting for sending me email from charger. If I know charger of this problem, I will send only charger to download URL of execution environment tarball file. because I would not like to broadcast download URL other member. By the way, this tarball file size is 3.1GB, please pay attention to download.
