Detailed Description

A locality is a partition of computational resources dedicated to fom execution on the node.

Resources allotted to a locality are:

  • fraction of processor cycle bandwidth;
  • a collection of processors (or cores);
  • part of primary store.

Once the locality is initialised, the locality invariant, should hold true until locality is finalised.
