Hello Luke,
at our windows cluster everything is working very well. We have 8 nodes,
WindowsServer2003 and mpich2 (1.0.7).
Attached a small testcode and sessionInfo()
I did some bigger tests using my "afyPara" package. There were no problems.
There was an other discussion at the Rd list. Giuseppe confirmed, that
DeinoMPI & Rmpi & the new version of snow is working very well.
See you in Seattle at the BioC2008 or Developer Day? I will fly to
Seattle tomorrow.
Best regards
Markus

Thanks.
Did you have a chance to check this on your WIndows setup?

It would be great to have a kind of change log in the package. To
know the latest changes.

A new version of the 'snow' package for parallel computing in R is
available at
http://www.stat.uiowa.edu/~luke/R/cluster/snow_0.3-3.tar.gz
This substantially revises the way in which worker processes are
started to allow snow to be used on Windows and Mac/Windows/Linux
combinations. I have successfully used the SOCK version on a
standalone Windows machine and combinations of Windows and Linux; the
MPI version also works for me with DeinoMPI and the Rmpi verision for
DeinoMPI.
I would welcome it if some current snow users could try this verison
in their settings to help iron out any major issues I missed before
release to CRAN.
Thanks,
luke
