omp: Support for parallel computation

In CautiousLearning: Control Charts with Guaranteed In-Control Performance and Cautious Parameters Learning

Description

The functions can be used

• to check if the current system supports the openMP standard;

• to control the number of used cores;

• to set the seeds of the random number generators.

Usage

hasOMP()

setOMPThreads(nthreads)

setSITMOSeeds(seed)

Arguments

nthreads	number of OpenMP threads to be used.
seed	number between 0 and 1 used to set the seeds of the random number generators in each threads.

Details

Each openMP thread (or the single thread used on systems where openMP is not supported) uses a separate sitmo random number generator. See sitmo-package.

Value

Function hasOMP returns TRUE/FALSE if the system supports/does not support openMP.

Functions setOMPThreads and setSITMOSeeds do not return any value.

Note

When the package is loaded, the following code is automatically executed

• if (hasOMP()) setOMPThreads(parallel::detectCores())

• setSITMOSeeds(runif(1))
