Hello, 

I am new to MPI and I went and installed mpich2 1.4.1 onto a windows system that is being used through cygwin. I have compiled the code that simply prints the process and rank as shown below. 



#include <stdio.h> 
#include <mpi.h> 

int main( int argc, char *argv[]) { 
int numprocs, rank, namelen; 
char processor_name[MPI_MAX_PROCESSOR_NAME]; 

MPI_Init(&argc, &argv); 
MPI_Comm_size(MPI_COMM_WORLD, &numprocs); 
MPI_Comm_rank(MPI_COMM_WORLD, &rank); 
MPI_Get_processor_name(processor_name, &namelen); 

printf( "Process %d on %s out of %d\n" , rank, processor_name, numprocs); 

MPI_Finalize(); 
} 

Nothing too complicated. However, I still receive an error from the command line in cygwin that simply reads segmentation fault: (core dumped). The command I used was: 

mpiexec -n 1 a.exe 

No matter what executable I try to run, I still receive the same error. Any help regarding this would be greatly appreciated!
