RcppParallel

CRAN R-CMD-check <!-- badges: end -->

High level functions for parallel programming with Rcpp. The parallelFor() function can be used to convert the work of a standard serial "for" loop into a parallel one, and the parallelReduce() function can be used for accumulating aggregate or other values.

The high level interface enables safe and robust parallel programming without direct manipulation of operating system threads. On Windows, macOS, and Linux systems, the underlying implementation is based on Intel TBB (Threading Building Blocks). On other platforms, a less-performant fallback implementation based on the TinyThread library is used.

For additional documentation on using RcppParallel see the package website at http://rcppcore.github.io/RcppParallel/.

Intel TBB

RcppParallel supports the new interface of Intel TBB, and can be configured to use an external copy of TBB (e.g., with oneTBB or the system TBB library), using the TBB_LIB and TBB_INC environment variables.

To build the development version of RcppParallel with oneTBB:

For example, installing oneTBB on Linux 64-bit (x86_64) to $HOME directory (change if needed!):

```bash TBBRELEASE="https://api.github.com/repos/oneapi-src/oneTBB/releases/latest" TBBTAG=$(curl --silent $TBBRELEASE | grep -Po '"tagname": "\K.*?(?=")') TBBVERSION=${TBBTAG#?}

wget https://github.com/oneapi-src/oneTBB/releases/download/v$TBBVERSION/oneapi-tbb-$TBBVERSION-lin.tgz tar zxvf oneapi-tbb-$TBB_VERSION-lin.tgz -C $HOME

export TBB="$HOME/oneapi-tbb-$TBBVERSION" `` Note that you may replaceTBBVERSION=${TBB_TAG#?}` with a custom version number if needed ( check available releases here ).

  • Set the TBB environment variables (specifically: TBB for the installation prefix, TBB_INC for the directory that includes the header files, and TBB_LIB for the libraries directory).

For example, installing oneTBB on Linux 64-bit (x86_64) to $HOME directory (change if needed!):

```bash source $TBB/env/vars.sh intel64

export TBBINC="$TBB/include" export TBBLIB="$TBB/lib/intel64/gcc4.8" ```

  • Build the development version of RcppParallel:

r install.packages("remotes") remotes::install_github("RcppCore/RcppParallel")
