Hello R experts,
I've been searching for weeks a way to use my quad core xeon to increase
speed of a very-very computer-intensive simulation I must do for my works.
It seems that most purpose-made packages for R : Snow, Rmpi, snowfall,...
are designed for Linux based OS. I do not have access to Linux due to
professionnal reasons ... so I must work with windows XP.
Do somebody know a way to unleash the calculation power of all four cores
under windows XP ?
Just tried snow under Windows 2000 and it works. Just follow the
examples on http://www.sfu.ca/~sblay/R/snow.html
but create a cluster as follow:
cl <- makeSOCKcluster(c("localhost", "localhost", "localhost", "localhost"))
and you have a cluster of all your four cores.
As I don't have a dual or quadcore running windows, I can't confirm
that it is actually using all cores (it does under Linux), but the
cluster is created.
If you have further questions, just ask - I am learning tio use snow as well.
