how does the master receive results from the workers? if a worker is sending multiple task results, how does the master knows what the message tags are ahead of time?

Dear All : 

I designed a master-worker framework, in which the master can schedule
multiple 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
