[mpich-discuss] 答复:Re: Can MPICH2 handle the fault that some processes die irregularly

[ejoywx]

Thanks for Darius's idea. And I find in the blocking communiction, if a process failed, all others process will die.
Today I attemped to program in the nonblocking communiction. However in my test programs, if a process failed to die ,another process still was alive and able to do its business normally.
Thank mpich-discuss mailing list!

We are working on improving detection of and tolerance to failed processes.  The next release should include many improvements.

But for me, "Can MPICH2 handle the fault that some processes die irregularly" , it is very important: In our computer cluster, I find if a process dies in some node or a node is shutdown, all process of the cluster will die. We attempt to register a error handler to deal with such fault, unfortunately, We fail!
