Method Detail

• getExecutorService

  public static ExecutorService getExecutorService(int nThreads)

  Returns an ExecutorService for Callables that use nThreads number of threads.

  Parameters:

  nThreads - the number of Threads used by a given Callable.

  Returns:

  an ExecutorService that will execute as many Callables as possible for the given number of Threads-per-Callable. For instance, on a machine with 4 cpus (as returned by Runtime.getRuntime().availableProcessors() ), calling getExecutorService(2) will return an ExecutorService that will run 2 ( 4 / 2 ) Callables at a time.

• getExecutorService

  public static ExecutorService getExecutorService(float fractionThreads)

  Returns an ExecutorService for Callables that use a given fraction of computer resources.

  Parameters:

  fractionThreads - the fraction of resources that a submitted Callable is expected to need.

  Returns:

  an ExecutorService that will execute as many Callables as possible for the given resource fraction. For instance, getExecutorService(1.0f) will return an ExecutorService that will run only one Callable at a time.
