Parallelization

Parallelization
is an option for Compile that specifies whether it should create a compiled function that could run in parallel.
MORE INFORMATION
  • Compiled functions only run in parallel if Listable is one of the RuntimeAttributes and the function threads over list arguments.
  • Compiled functions run in parallel using multiple threads of execution.
  • If a compiled function running in parallel has several threads trying to call ordinary Mathematica code, only one thread can do this at any time.
  • The following settings can be used:
Truecreate parallel code
Falsecreate single-thread code
Automaticuse parallelization for optimal arguments

Listable compiled functions can execute in parallel:
This shows the operation running sequentially:
Typically, $ProcessorCount is used to determine how many threads can be used:
