[Boost-users] boost MPI, cannot get the results from workers

Subject: [Boost-users] boost MPI, cannot get the results from workers

Dear All : 
I designed a master-worker framework with boost MPI, in which the master can schedulemultiple tasks (numTaskPerWorkerNode) to each worker and then collects results from workers.
if the numTaskPerWorkerNode = 1, it works well. 
But, if numTaskPerWorkerNode > 1, the master cannot get the results from workers. 
But, the workers can get the tasks from master. 
why ?

I have used different taskTag to distinguish the tasks, but still does not work.
Any help is appreciated. 
Thanks, 
Jack
