I am using Open MPI 1.4.3.
I have to perform a receive operation from processes that are sending
data. It might happen that some of the processes don't send data
(might have completed in-fact).
So, how do I perform check on which processes to receive data from and
which processes to skip?
if(id != master)
MPI::COMM_WORLD.Send(&dist, NUM_VERTEX, MPI_LONG, master, 1234);
if(id == master)
for(int eachId = 1; eachId<procs ; eachId++)
MPI::COMM_WORLD.Recv(&dist1, NUM_VERTEX, MPI_LONG, eachId, 1234);
