Snow and multi-processing
...ck script cl <- makeCluster(nnodes,method) mArrayData <- getData(experiments) clusterExport(cl, 'mArrayData') Results <- parLapply(cl, theMapList, function(x) t.testFnc(x)) With a function that define the mArrayData argument as a default parameter as in t.testFnc <- function(probeList, array=mArrayData){ x <- array[probeList$A,] y <- array[probeList$B,] res <- doSomeTest(x,y) return(res) } Using this strategy, I was able to gain full advantage of my cluster and reduce the analysis time by the number of nodes I have in our cluster. The large data matrix...
