This repository is now deprecated and will no longer be maintained.\n\n---\n\n# r-parallel\n\nThis is a Docker-based Linux container that consists of the base [R] installation, by extending the [rocker/r-base] container, together with several system libraries and R packages useful for parallel/asynchronous processing.\n\n\n## Build\n\nTo build the container locally, do:\n\n```sh\n$ docker build . --tag henrikbengtsson/r-parallel\nSending build context to Docker daemon 56.32kB\nStep 1/17 : FROM rocker/r-base\nlatest: Pulling from rocker/r-base\n28507814f909: Pull complete

Hub, do:\n\n```sh\n$ docker pull henrikbengtsson/r-parallel\nUsing default tag: latest\nlatest: Pulling from henrikbengtsson/r-parallel\n[...]\n\n$ \n```\n\n\n## Usage\n\n### Standalone\n\nTo launch R by itself, do:\n\n```sh\n$ docker run -ti henrikbengtsson/r-parallel\n\nR version 3.5.1 (2018-07-02) -- \"Feather Spray\"\nCopyright (C) 2018 The R Foundation for Statistical Computing\nPlatform:

workers that are running in their own [Docker] container, _from the R installation installed on the host system_, do:\n\n```r\n$ R --quiet\n\n> library(parallel)\n> cl <- future::makeClusterPSOCK(rep(\"localhost\", times = 2L), rscript = c(\n \"docker\", \"run\", \"--net=host\", \"henrikbengtsson/r-parallel\", \"Rscript\"\n ))\n> print(cl)\nsocket cluster with 2 nodes on host ‘localhost’\n\n> y <- parSapply(cl, 1:3, function(x) sqrt(x))\n> y\n[1] 1.000000 1.414214 1.732051\n\n> stopCluster(cl)\n```\n\nTo do the same using [Singularity], do:\n\n```r\n> library(parallel)\n> cl <- future::makeClusterPSOCK(rep(\"localhost\", times = 2L), rscript = c(\n \"singularity\", \"exec\", \"docker://henrikbengtsson/r-parallel\", \"Rscript\"\n ))\n> print(cl)\nsocket cluster with 2 nodes on host ‘localhost’\n\n> y <- parSapply(cl, 1:3, function(x) sqrt(x))\n> y\n[1] 1.000000 1.414214 1.732051\n\n> stopCluster(cl)\n```\n\n[R]:
