Subject: [OMPI users] Open MPI, cannot get the results from workers
From: Jack Bryan (dtustudy68_at_[hidden])

Dear All :
I designed a master-worker framework, 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
