&g
I do not see where you initialize the offset on the "Non-master tasks".
This could be the problem.

Hi Jeffy,
I checked the SEND RECV buffers and it looks ok to me. The code I have sent
works only when I statically initialize the array.
The code fails everytime I use malloc to initialize the array.
Can you please look at code and let me know what is wrong.

As a guess, you're passing in a bad address.
Double check the buffers that you're sending to MPI_SEND/MPI_RECV/etc.

Try malloc'ing your array instead of creating it statically on the stack.
Something like:
int *data;
int main(..) {
{
data = malloc(ARRAYSIZE * sizeof(int));
if (NULL == data) {
perror("malloc");
exit(1);
}
// ...
}
