I'm developing a distributed system with a communication layer based on Open
MPI. As part of my project, I have to create a process scheduler. So I
decided to use the MPI_Spawn function to dynamically create (it is an
requirement of the system) the process across the cluster's nodes.
Is there some way to specify how many copies of a process to spawn to each
node? For instance, I want to spawn 5 copies of a mpi program to 3 nodes
usin the scheme bellow:
*1 to host 1*
*3 to host 2*
*1 to host 3*
obs.: I am using openmpi-1.5.3. The default policies provided by the ompi is
not applicable to my problem because I will decide the scheme based on
Thanks in advance.
