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
newer slots=8 weight=0.95
newest slots=12 weight=1
So that CPUs of oldest (and slowest) machine gets less data to process.
