Markus,

That's interesting. I'm using snow_0.3-0 that's the version on CRAN. I see
that on the maintainer's website newer versions are available...

I just tried snow_0.3-3 and as you said it actually works fine!

Thanks a lot for the help, that's exactly what I was looking for!

Hello,

we are using Rmpi and snow on windows. It is working very well.
We are using Windows Server 2003 and *MPICH2.

I probably will manage to have some tests with the new snow
(*snow_0.3-3)* version this week.

Best
Markus
