Hi,

we are looking for a new workstation for big datasets/applications (easily
up to 100'000 records and up to 300 Variables) using R. As an example:
Variable Selection for a multivariate regression using stepAIC.

What is the best configuration for a workstation to reach a high performance
level for computing with R?

Single core or multi core (is R together with nws package really able to use
advantage of multi core processors, any experience/benchmarks on that)?

Shall we use Linux instead of Windows? If yes, how is the compatibility of
graphics computed on Linux if we like to use them after on windows? And what
are the advantages using Linux instead of Windows?

What kind of workstations are you using (hardware and operating system) for
big data computations? And are you satisfied with it?

I'm quite familiar with pc or server hardware.

Thanks in advance

Sascha Morach
