Re: [mpich-discuss] Error: failed to allocate memory for an unexpected message
Hi Wesley Bland, When I was searching on the Internet, I realized that it could because the mpich installed on these machines are too old. I found a FAQ entry as below : https://wiki.mpich.org/mpich/index.php/Frequently_Asked_Questions#Q:_I_don.2... I installed an up-to-date version of OpenMPI on these two machines. And the problem is gone. I guess a recent MPICH would help, too. Thanks very much for your time. On Thu, Oct 2, 2014 at 8:57 PM, XingFENG <[email protected]> wrote:
Hi Wesley Bland,
Thanks for your reply.
My codes is relatively big( around 2000 lines). I will try to make and post one small example later.

Can you provide a minimal example code that reproduced the problem?

Hi Wesley Bland,
Thanks for your reply.
I have modified my codes. For each process, it first receives then sends message from/to others. However, same error still appears.
I also noted that the code works fine for single node machine. It crushed with this error on multi-node cluster.

The problem in this situation usually is that you're not posting enough receives and too many of your messages are getting buffered by the MPI library. Make sure you match up your sends and receives and whenever possible you post your receives early.

Hi all,
I am running a MPI program on two machines. I got errors as follows:

====================================================================
I have never seen such errors before. What is the cause of this error? Is it an out of memory error? ( There is 20% remaining memory on machines )
Any help would be greatly appreciated. Thanks in advance!
