fatal error in mpi_wait Italy, Texas

I think both the mpich2 and openmpi problems are somewhat related. A 16-core run on a 16-core node succeeds, but fails on a pair of 12-core nodes. Is there any job that can't be automated? How many processes did you actually use??

Then anyone with a TCP socket open to that now-dead process receives a RST packet and bails out before the process manager can kill it. int dynamicDataLength = 0; dynamicDataSizes.resize(entry.messages.size()); for (pluint iMessage=0; iMessage

I don't see anything >>>> obviously wrong in your mpiexec verbose output (though >>>> I am not hydra expert). I haven't compiled the pythonic directory (From the user guide I believe it isn't necessary), however I know for a fact that I don't have Swig or the other libraries mentioned I just wanted to make sure that I wasn't overlooking somthing in the syntax or the way the code was setup. This list of combinations is not exhaustive, and I thought it was pretty clear that the problem arose when I tried to do a run involving more than one host/node.

It now runs with any array sizes. A Shadowy Encounter What kind of bicycle clamps are these? The bug fix has now been integrated in the newest Palabos release, and as of version 1.4 things should be fine. This can cause a job to hang indefinitely while it waits for all processes to call "init".

Thank you for your help. I'm sure I tried this combination yesterday and it failed then! 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. Is accuracy a binary?

I can successfully run codes under Platform MPI.

Thanks in advance!

I've also tried this with the Poiseuille showCase, and it works fine under all conditions. 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 URL: http://mailman.ucar.edu/pipermail/wrf-users/attachments/20090820/a6ff8680/attachment.html Previous message: [Wrf-users] CAM subgrid scheme and WRF regional climate simulations Next message: [Wrf-users] hardware questions Messages sorted by: [ date ] [ thread ] [ subject ] [ int main (int argc, char *argv[]) { .... ....

Everything runs fine. Looking for data to run the WRF? The LSF cluster is new and in testing, but the grid-engine cluster has been operational for many years. it is also troubling that you seem to be expecting a buffer size of 0 consistently.

Palabos also works fine under Platform-MPI. I've seen this problem in both Palabos 1.1 and Palabos 1.2. 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 int pos=0; for (pluint iMessage=0; iMessage

Italy. What is the most expensive item I could buy with £50? Sure enough, when all processes are on a single host, everything works, but when processes are spread across more than one host, the run fails. I just installed openmpi and recompiled WRF.

Note that you must have the PGI CDK product to use the MPI debugging feature. - Mat[/url] Back to top Display posts from previous: All Posts1 Day7 Days2 Weeks1 Month3 Months6 This can cause a job to hang indefinitely while it waits for all processes to call "init". it also happens when people misread or misuse the code or use incompatible or incorrect computations that collide with what LAMMPS is doing. I have also checked free memory during the run, its almost always ~2GB.
