| omp {CautiousLearning} | R Documentation |
Support for parallel computation
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))
