CPU binding
Chapter 3 61
-cpu_bind=MASK_CPU:1,4,6
# map rank 0 to cpu 0 (0001), rank 1 to cpu 2 (0100), rank 2 to cpu 1 or 2
(0110).
A rank binding on a clustered system uses the number of ranks and the
number of nodes combined with the rank count to determine the CPU
binding. Cyclic or blocked launch is taken into account.
On a cell-based system with multiple users, the LL strategy is
recommended rather than RANK. LL allows the operating system to
schedule the computational ranks. Then the -cpu_bind capability locks
the ranks to the CPU as selected by the operating system scheduler.
