[mvapich-discuss] Can you help me ?

[Qi Gao]

Hi,

Thanks for trying MVAPICH2. We are glad to work with you to solve the problem.

>From the log, it seems that MPI program is having trouble to connect to MPD for CKPT support. To help us to narrow down the problem would you plesae first verify the following things?
    1.  Are you using the make script "make.mvapich2.ofa" to compile & install MVAPICH2 and enabling CKPT by assigning the env in the script ENABLE_CKPT to yes?
    2.  Are you using the MPD provided in MVAPICH2 package as your process manager? That version of MPD includes the extended functionality to support CKPT.

Thanks.
