[mvapich-discuss] leaked context IDs detected

[Kumar, Amit]

Dear MVAPICH2-2.1 compiled using GCC-5.10

I see these strange messages after job completion. I see this not just for my own programs but even for establish applications like NAMD that are compiled with mvapich2.

Any insight into what these errors/information mean could be a great help.

Please let me know if you need more information.

Regards,
Amit
