Hello Everybody,

I am experiencing some problem is using MPI_Scatter.

#include <mpi.h>
int MPI_Scatter(void* sendbuf,int sendcount,MPI_Datatype sendtype,void* recvbuf,
                int recvcount,MPI_Datatype recvtype,int root,MPI_Comm comm);

Is there any limit on number of elements (data) to be sent from root processes
to other processes? I am using MPI_scatter to send data from root to rest of
the nodes. It works fine for smaller number of *sendcount* (e.g. 100) but gives
error that message truncated for larger number (100x100x5) of sendcount.

Pls clarify.

Thanks,
