When I run a MPI program then the following error has shown. I dont know why..Some times it shows and sometimes not...sometimes work properly....
What the problem?
What i have done is here.. 
>From master node i send 55 data set to 5 processors by a MPI_SEND() with in a loop...
the slaves receive by MPI_Recv() with in a loop and again send all data set to the master by using MPI_Recv() with in a loop..
The loop is used for how many data they receive and how many data they send just keep the track...
$ time mpirun -np 5 a.out 
0 - MPI_RECV : Message truncated
[0]  Aborting program !
