Hi, I am running a pipeline on an Ignite cluster. I want to limit the number of tasks started both on the head and on each node, but it seems that neither the nodes nor the head respect the -cluster.slots parameter. Should I be using some other parameter to limit the number of tasks that are run in parallel on each node?

where did u find -cluster.slots ?

Using 5 machine in the Amazon Cloud. The machines are "fixed" so to me it is just like they are local (except no multicast).
