It is. From http://cran.r-project.org/bin/windows/contrib/2.6/ReadMe Although the packages ROracle, and snow pass make check, it seems to be dangerous to distribute them: I do not have the software available these packages depend on. It compiles from the sources, and using snow alone you can run socket clusters on Windows (by default it expects ssh to be running, and Windows machines rarely run an ssh daemon so as to accept incoming ssh). The caution is that the packages runs no tests so needs manual intervention to test it, and in particular most people will want to run snow over Rmpi which does not compile on Windows without more software (and some effort). It might be worth modifying snow to more easily run multiple processes on a single machine. >I have been able to get the nws package to work > on a duel core machine using windows and it did speed up my tests (and > was fairly straight forward to use).
