-// specified MPI rank, local rank, and thread.
-//
-// The cpu list has for example a format of: 0,1,2 or 0,1,2_3,4,5
-//
-// Blocks (0,1,2 or 3,4,5) separated by "_" specify pinning inside a
-// node rank. The first block maps to node rank 1, the second to node
-// rank 2, etc.
-//
-// Inside a block the core numbers specify where the threads should
-// be pinned to. They are separated by "," and the first number maps
-// to the first core, the second number to the second core, etc.
-//
-// For example: 0,2,4_6,8,10
