I have 10 nodes, including 1 master node and 9 slave nodes. I have 100 tasks. The master node will collect information about the status of slave nodes and tasks. Once the master node find a avaliable slave node, it will assign a task to the slave node. Once a slave node finished a task, it will let the master node know its node id and the task id. Only one task is assigned to a slave node each time. The processure will continue untile all tasks are done. Do you know to code with MPI/OpenMP? Any example codes are highly appreciated.<BR /><BR />Thanks,<BR />White<BR /><BR /> Fri, 06 May 2011 14:27:48 GMT https://community.intel.com/t5/Intel-Moderncode-for-Parallel/Any-examples-about-MPI-OpenMP/m-p/827800#M1425 white888 2011-05-06T14:27:48Z https://community.intel.com/t5/Intel-Moderncode-for-Parallel/Any-examples-about-MPI-OpenMP/m-p/827801#M1426 It's certainly feasible to run OpenMP within an MPI rank.
