Good day,
I'm trying the example cl <- makeCluster(2, type = "SOCK")
Why use the 'snow' package and not 'parallel'?
from the makeCluster documentation and the R command prompt never
returns. I am using a 32-bit Windows 10 computer. The problem doesn't
happen on another 64-bit Windows 10 computer but does happen on
another 32-bit Windows 7 computer. Can anyone reproduce it? Are there
any other options that can be passed to makeCluster which could get
it going?
Sorry, I don't have access to a 32-bit W10 machine for testing.
Since the worker processes communicate using sockets I guess that the
Windows firewall on your machine is blocking R from using the necessary
ports (11000-11999). Upon first use on a freshly installed 64-bit W10 a
window pops-up -- "Windows Firewall has blocked this app", or something
like that -- where you can allow access. As long as this window is
open, the command prompt is not returned.

P.S. This topic is probably not appropriate for R-devel and follow-ups
should likely be directed to R-help instead. D.S.
