fatal error in mpi_wait other mpi error King George, Virginia

I changed the appropriate flags in the Makefile) and it compiles fine. If you're going to have several pending requests, you're best off having several MPI_Requests and statuses in an array (eg, MPI_Request reqs[5]; MPI_Status stats[5];) and then using them one at a double *northedge1 = new double[Rows]; double *northofnorthedge3 = new double[Rows]; ... ...

It seems strange that it should happen in an out-of-the-box sample code. My question is, do I have to take a look at the order of Send/Recv commands or should each MPI_Recv should be followed by an MPI_Wait command? Is intelligence the "natural" product of evolution? This time, the error messages are slightly different, with some std::bad_alloc messages.

Any suggestion is greatly appreciated........ The code runs on a single 16-node host, but fails on a 32-node host. Thanks in advance! On the send side, it looks like the allocation of memory for the mpich2 internal send request fails without giving a very useful error traceback.

And now I have fixed it, I found that in src/parallelism/sendRecvPool.cpp: void SendPoolCommunicator::startCommunication(int toProc, bool staticMessage) { std::map::iterator entryPtr = subscriptions.find(toProc); PLB_ASSERT( entryPtr != subscriptions.end() ); CommunicatorEntry& entry = entryPtr->second; std::vector Your "bad_alloc" exceptions show a failure to allocate memory, but I cannot imagine where this would come from, since the problem is a 2D one on a 100x100 grid.

A 16-core run on a 16-core node succeeds, but fails on a pair of 12-core nodes. By rule, if one process calls "init", then ALL processes must call "init" prior to termination. 2. However, when the processes are spread across more than one host, the run fails with the error messages below. Has anyone encountered this?

I did "mpdboot -f hostfile" $ cat hostfile node 1 node 23. I've now tried to compile and run cylinder2d, which is part of the showCases folder. Thanks, 11bolts.

In the above, it looks like you should have if ( (my_rank == 1) || (my_rank == 3)) MPI_Wait(&send_request, &status); share|improve this answer answered May 17 '11 at 20:41 Jonathan Dursi I've seen this problem in both Palabos 1.1 and Palabos 1.2.

I would suggest several things: 1) see if you can reduce the memory requirements/node for the job you are trying to run, maybe by running on more nodes. 2) contact nersc By rule, all processes that call "init" MUST call "finalize" prior to exiting or it will be considered an "abnormal termination" This may have caused other processes in the application to this process did not call "init" before exiting, but others in the job did. Palabos also works fine under Platform-MPI.

Thank you for your help. Why are empty blocks not all the same size? Thank you, Kevin Regards, Kevin RSS Top 4 posts / 0 new Last post For more complete information about compiler optimizations, see our Optimization Notice. Is there any job that can't be automated?

Do you have these libraries installed? Send them the error message output as they can correlate it with syslog output on the smw to see if there were out-of-memory conditions on the nodes you were using today. asked 5 years ago viewed 2163 times active 5 years ago Linked 0 Non Blocking communication in MPI and MPI Wait Issue.
