Uwe,
Good news. I installed 3.0.2, and the parallel package examples ran
successfully. This time a firewall window popped up. Probably the
firewall was the problem with the snow package too, but for some reason the
window didn't pop up with the snow package.
Great new.
Thanks for the suggestion to use "parallel". I noticed that the package is
brand new! Or, at least the pdf help was written 9/25/13.
Not that new, just updated.
Best,
Uwe

Can you please upgrade R to R-3.0.2 and use the parallel package?
And can you please explain why you want to start the workers manually? I'd
be happy to look into the details if you can reproduce the problem with a
recent version of R and the parallel package.
Best,
Uwe Ligges

This is in regards to the SNOW library.
I'm using Windows. The problem is that makeSOCKcluster hangs in R as well
as the DOS command line. Below I've shown that it completes the Rscript
until it reaches the line "slaveLoop(master)" , at which point it hangs.
=============================
In R:
cl <-
makeSOCKcluster(names=c("**localhost","localhost"),**
manual=T,outfile="jeff.log")
Manually start worker on localhost with
C:/PROGRA~1/R/R-214~1.2/bin/**Rscript.exe "C:/Program
Files/R/R-2.14.2/library/snow/**RSOCKnode.R" MASTER=localhost PORT=11590
OUT=jeff.log SNOWLIB=C:/Program Files/R/R-2.14.2/library
[HANGS]
==============================**==
On the DOS Command Line:
C:\Documents and Settings\Jeff>C:/PROGRA~1/R/R-**214~1.2/bin/Rscript.exe
"C:/Program Files/R/R-2.14.2/library/snow/**RSOCKno
de.R" MASTER=localhost PORT=11590 OUT=jeff.log SNOWLIB=C:/Program
Files/R/R-2.14.2/library
[HANGS]
^C
C:\Documents and Settings\Jeff>type jeff.log
starting worker for localhost:11590
==============================**======
In the file RSOCKnode.R, stalls after last line, after executing
"slaveLoop(master)".
local({
master <- "localhost"
port <- "8765"
snowlib <- Sys.getenv("R_SNOW_LIB")
outfile <- Sys.getenv("R_SNOW_OUTFILE")
args <- commandArgs()
pos <- match("--args", args)
args <- args[-(1 : pos)]
for (a in args) {
pos <- regexpr("=", a)
name <- substr(a, 1, pos - 1)
value <- substr(a,pos + 1, nchar(a))
switch(name,
MASTER = master <- value,
PORT = port <- value,
SNOWLIB = snowlib <- value,

##**** these should be passed as arguments to makeNWSmaster
Sys.setenv(MASTER = master)

Sys.setenv(RANK = rank)
Sys.setenv(TMPWS = tmpWsName)
if (! (snowlib %in% .libPaths()))
.libPaths(c(snowlib, .libPaths()))
library(methods) ## because Rscript as of R 2.7.0 doesn't load
methods
