so i'm still not sure if i've built this correctly to begin with, since the crash is caused in mpich-master-3.0.3/src/pmi/pmi2/simple2pmi.c so not sure if that should be using slurm's pmi2 plugin or if this is potentially an issue i should enquire about on the mpich forum ? this is my code: #include "mpi.h" #include <iostream> int main(int argc, char *argv[]) { MPI_Init(&argc, &argv); int rank,c_size; MPI_Comm_size( MPI_COMM_WORLD, &c_size ); MPI_Comm_rank( MPI_COMM_WORLD, &rank ); std::cerr << "Hello World from rank " << rank << " / " << c_size << std::endl; MPI_Finalize(); } with LF -lpthread -lmpich Kind Regards, Christoph On 29/03/13 22:49, Hongjia Cao wrote: > could you please paste the complete output/error messages? > > 在 2013-03-28四的 14:59 -0600,Christoph Sprenger写道: >> pich.so.10(PMI2_Init+0x7ff)[0x7f5daff7806f] >> /tech/home/csprenger/mpich-3.0.2_SLURM//lib/libmpich.so.10(MPID_Init >> +0xac)[0x7f5daff371ac] >> /tech/home/csprenger/mpich-3.0.2_SLURM//lib/libmpich.so.10(MPIR_Init_thread+0x240)[0x7f5dafff90d0] >> /tech/home/csprenger/mpich-3.0.2_SLURM//lib/libmpich.so.10(MPI_Init >> +0xb1)[0x7f5dafff8a41] >> >>
