Hi, 
Thanks for all your reply. 
I attached the code in the email. 
I downloaded : Rhapsodia.Schedulerfrom http://rhascheduler.sourceforge.net/because I need to do application program level task scheduling. 
In file "TaskPackSystem.hpp", I designed a task class "TaskPackage" to carry my defined task.
Other classes in the file are not used. 
My main program is mpi_message_transfer.cpp, which can transfer tasks from master to workers and then collects results from them. 

Right now, I am testing 3 tasks (TOTALTASKNUM =3) and 2 workers (nodes). 
I use 3 nodes totally, another node is the master. 
node 0 : is master.
node 1 : worker 1 assigned with task 1 and 3. 
node 2 : worker 2 assigned with task 2. 
Each task has a distinct tag, which is assigned by master before it is sent out to a worker. 
After receiving a task and doing its local work on the task, the worker uses the same tag ID to send it to master. 
The master use non-blocking world.recv(resultSourceRank, tagID, resultTaskPackage) to get the result task. 
You may need to download the Rhapsodia.Scheduler to get their header files. 
I attached the 4 files in the email. 
mpi_message_transfer.cppTaskPackSystem.hppBasicScheduler.hppSimpleScheduler.hpp

Any help is appreciated. 
thanks
Jack
