Hello all. I'm having problems running a simple program. I built lam
7.1.1 with the intel 9.1 compiler. When running the following program:
#include <iostream>
#include <mpi.h>
using namespace std;
int main()
{
// Do initial MPI setup stuff...
MPI::Init();
int rank = MPI::COMM_WORLD.Get_rank();
int ncount = MPI::COMM_WORLD.Get_size();
cerr << "rank " << rank << endl;
cerr << "ncount " << ncount << endl;
}
I get the following error:
mpirun -np 1 ./prog
MPI_Comm_rank: invalid communicator: Invalid argument (rank 0,
MPI_COMM_WORLD)
Rank (0, MPI_COMM_WORLD): Call stack within LAM:
Rank (0, MPI_COMM_WORLD): - MPI_Comm_rank()
Rank (0, MPI_COMM_WORLD): - main()
-----------------------------------------------------------------------------
One of the processes started by mpirun has exited with a nonzero exit
code. This typically indicates that the process finished in error.
If your process did not finish in error, be sure to include a "return
0" or "exit(0)" in your C code before exiting the application.
PID 26802 failed on node n0 (127.0.0.1) with exit status 22.
-----------------------------------------------------------------------------
If I use the 9.1 compiler and the version of lam I built with the 9.0
compiler everything work fine.
icpc -I/ll/3rdptysw/x86_64-Linux-2.4-icc-9.0/include -pthread prog.C -o
prog -L/ll/3rdptysw/x86_64-Linux-2.4-icc-9.0/lib -llammpio -llammpi++
-llamf77mpi -lmpi -llam -laio -laio -lutil -ldl
When I compile with lam built with 9.1 it breaks.
icpc -I/ll/3rdptysw/x86_64-Linux-2.4-icc-9.1/include -pthread prog.C -o
prog -L/ll/3rdptysw/x86_64-Linux-2.4-icc-9.1/lib -llammpio -llammpi++
-llamf77mpi -lmpi -llam -laio -laio -lutil -ldl
