Parallel computation

The dodgr package implements most calculations by default in parallel, using the maximum number of available threads or cores. Numbers of available threads can be determined with either of the following two functions:

parallel::detectCores ()

## [1] 12

RcppParallel::defaultNumThreads ()

## [1] 12

Numbers of cores used in calculations can be controlled by specifying the numThread parameter passed to the RcppParallel function setThreadOptions. For control over numbers of threads used, this function must be called prior to calling any dodgr functions. For example, single-threaded processing can be ensured by first making the following call:

RcppParallel::setThreadOptions (numThreads = 1L)
