A master R process calls makeCluster\nto start a cluster of worker processes; the master process then uses\nfunctions such as clusterCall and clusterApply to execute R code on\nthe worker processes and collect and return the results on the master.\nThis framework supports many forms of \"embarrassingly parallel\"\ncomputations.\n\nSnow can use one of four communications mechanisms: sockets, PVM, MPI,\nor NetWorkSpaces (NWS).  NWS support was provided by Steve Weston.\nPVM clusters use the rpvm package; MPI clusters use package Rmpi; NWS\nclusters use package nws.  If pvm is used, then pvm must be started,\neither using a pvm console (e.g the pvm text console or the graphical\nxpvm console, both available with pvm) or from R using functions\nprovided by rpvm.  Similarly, LAM-MPI must be started, e.g.  using\nlamboot, for MPI clusters that use Rmpi and LAM-MPI.  If NWS is used,\nthe NetWorkSpaces server must be running.  SOCK clusters are the\neasiest approach for using snow on a single multi-core computer as\nthey require no additional software.","flavors":[],"html":"https://daemonports.org/midnightbsd/science/R-cran-snow/","kind":"port","lastUpdate":null,"license":["gpl2+"],"maintainer":"ports@MidnightBSD.org","name":"snow","newest":false,"newestVersion":"20130616","noVulnData":true,"origin":"science/R-cran-snow","otherSystems":[{"maintainer":"tota@FreeBSD.org","origin":"science/R-cran-snow","path":"/science/R-cran-snow/","system":"FreeBSD","updated":"2026-09-18","version":"0.4.4_1"},{"maintainer":"agc@NetBSD.org","matchedBy":"name","newest":true,"origin":"security/snow","path":"/netbsd/security/snow/","system":"NetBSD","version":"20130616"},{"maintainer":"tota@FreeBSD.org","origin":"science/R-cran-snow","path":"/dragonfly/science/R-cran-snow/","system":"DragonFly","version":"0.4.4_1"},{"maintainer":"tota@FreeBSD.org","noVulnData":true,"origin":"science/R-cran-snow","path":"","system":"HardenedBSD","version":"0.4.4_1"},{"maintainer":"tota@FreeBSD.org","noVulnData":true,"origin":"science/R-cran-snow","path":"","system":"GhostBSD","version":"0.4.4_1"}],"packages":null,"pkgName":"snow-0.4.4_1","related":null,"repository":"mports","requiredBy":[],"requiredByCount":0,"runDepends":[],"status":null,"system":"midnightbsd","systemLabel":"MidnightBSD","version":"0.4.4_1","versions":null,"vulnerabilities":null,"www":"https://cran.r-project.org/web/packages/snow/"}
