    Description

      For many workflows, there is a distinct performance advantage to avoiding transfer of a task between processors. For example when iteratively processing a small dataset keeping everything local to a single CPU can avoid churn in split caches. Allowing each logical core to be accessible as an Executor would be one way to give developers the requisite control.
