Varying numbers of slots are not a problem. But Mickaël's mail

Hi,
Maybe Mickaël means load balancing could be achieved simply by
spawning various number of MPI processes, depending on how many cores
particular node has? This should be possible, but accuracy of such
balancing will be task-dependent due to other factors, like memory
operations and communicatio
I'm afraid you'll have to do this kind of load balancing in your
application itself as Open MPI (just like any other MPI implementation)
has no notion of how your application manages its workload.

Hi,
Is there a way to define a weight to the CPUs of the hosts. I have a
cluster made of machine from different generation and when I run a
process on it, the whole cluster is slowed down by the slowest node.
What I'd like to do is something like that in my hostfile:
oldest slots=4 weight=0.75
