Hi friends,I'm trying to write a simple parallel master/slave program.Here in
my program the task of master is to distribute a randomly filled array to the
workers.And each worker have to print a part of the array. That's all what i
want to do.
The master need to make run the workers each time.
Hi,
master() never MPI_Bcast(dojob=2, c...), hence the hang
Cheers,
Gilles
