https://community.intel.com/t5/Intel-Moderncode-for-Parallel/problems-with-mpich/m-p/900718#M4198 Hi,<BR /><BR />I have a cluster with windows HPC server 2007 service pack 1<BR />I can not run communicative commands of mpi on the system.<BR /><BR />when I run the following simple code on 2 nodes using one core on each:<BR />--------------------<BR />use mpi<BR />implicit real*8(a-h,o-z)<BR /><BR />call MPI_Init ( ierr )<BR />call MPI_Comm_rank ( MPI_COMM_WORLD, my_id, ierr )<BR />CALL MPI_COMM_SIZE ( MPI_COMM_WORLD, NUM_PROCS, IERR )<BR /><BR />print*,my_id, NUM_PROCS<BR /><BR />call mpi_barrier(mpi_comm_world,ierr)<BR /><BR />print*,my_id, NUM_PROCS<BR /><BR />call MPI_Finalize ( ierr )<BR />end<BR />--------------------<BR /><BR /><BR /><BR />It does the first printing, but On mpi_barrier, It return error: rank 0 unable to connect to rank 1 using business card(33709,....)<BR /><BR />mpi_barrier error,<BR />I have the sam eproblem with all subroutines: mpi_bcast, mpi_reduce,.... and all subroutines that need communication.<BR />But If I want it to print ranks, or each cpu do some operations on its own, It does. I have run this code with the same version of mpich on a pc with windows xp, cammunicating through ethernet with a laptop with windows vista. please help me out.<BR /><BR />Regards<BR />Parsa<BR /> Tue, 19 May 2009 10:48:49 GMT parsa_banihashemi 2009-05-19T10:48:49Z https://community.intel.com/t5/Intel-Moderncode-for-Parallel/problems-with-mpich/m-p/900718#M4198 Hi,<BR /><BR />I have a cluster with windows HPC server 2007 service pack 1<BR />I can not run communicative commands of mpi on the system.<BR /><BR />when I run the following simple code on 2 nodes using one core on each:<BR />--------------------<BR />use mpi<BR />implicit real*8(a-h,o-z)<BR /><BR />call MPI_Init ( ierr )<BR />call MPI_Comm_rank ( MPI_COMM_WORLD, my_id, ierr )<BR />CALL MPI_COMM_SIZE ( MPI_COMM_WORLD, NUM_PROCS, IERR )<BR /><BR />print*,my_id, NUM_PROCS<BR /><BR />call mpi_barrier(mpi_comm_world,ierr)<BR /><BR />print*,my_id, NUM_PROCS<BR /><BR />call MPI_Finalize ( ierr )<BR />end<BR />--------------------<BR /><BR /><BR /><BR />It does the first printing, but On mpi_barrier, It return error: rank 0 unable to connect to rank 1 using business card(33709,....)<BR /><BR />mpi_barrier error,<BR />I have the sam eproblem with all subroutines: mpi_bcast, mpi_reduce,.... and all subroutines that need communication.<BR />But If I want it to print ranks, or each cpu do some operations on its own, It does.
