[mpich-discuss] mpich problem.... net_send: could not write to fd=4, errno = 32

Looks like there was a seg fault. Probably a bug in your program. If it left
behind a core file, you can run gdb on the core file.

fd=4,errno = 32


Hi. I'm trying to run this:
 /opt/mpich/gnu/bin/mpirun -v -np 4    -machinefile program

but i get this error:

CHECK 1

p0_32481:  p4_error: interrupt SIGSEGV: 11
Killed by signal 2.
Killed by signal 2.
Killed by signal 2.
p0_32481: (0.597656) net_send: could not write to fd=4, errno = 32



This is the code:

#define TAG_TASK 1
.
.
.
//i'm master******************************
printf("\n\nCHECK 1\n\n");

MPI_Ssend(task, 2, MPI_INT, node, TAG_TASK, MPI_COMM_WORLD);

printf("\n\nCHECK 2 \n\n");


//i'm slave********************************
MPI_Recv(task, 2, MPI_INT, 0, MPI_ANY_TAG, MPI_COMM_WORLD, &status);

And this is my machine file:

beta.something.com
compute-1-0.local
compute-1-1.local
compute-1-2.local

Any solution?


Thank you.
