Re: [Boost-users] Boost MPI, error to get message

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 July 5 2010

Hi, Jack,

May I know why I cannot try boost MPI directly ?

Boost.MPI is just a wrapper for various MPI implementations. If you cannot make your program using native MPI, you cannot make your program work with Boost.MPI.
