Parallel R

Thanks for that I hadn't realised parallel could run on windows Pc's.

The code is differential evolution but its not part of a package.

Still I would like to be able to use cloud computing if possible, any
thoughts on the easiest way to achieve that using a windows based PC?

Why does your local operating system dictate the backend OS used by
the cloud servers? I'd use what your servers already have on them -- R
should run more or less identically. (For the record, I believe linux
backends will be more performant in general)

Found this blog which seems to give pretty clear instructions:

and was also recommended cloudRmpi package.

Have you experience with either of these?

Please quote context for the (vast majority of) readers who don't use Nabble.

No, I don't have experience with those, but you may try the R-SIG-HPC
list for a more focused audience.

Cheers,
Michael
