[R] R benchmarking program

[Baker D.J.]

Hello Philippe,

Thank for your reply. I agree that this is an interesting project. As I say we have just started to buy Intel quad core machines after years of offered a service on AMD machines. I recompiled R with the GoTo BLAS, and did some basic tests..things like matrix cross products, solve, svd, etc, etc. The speed up on the Intels was stunning vs our AMD machines. Previously we have always worked with R + ACML BLAS on the AMDs (perhaps we have missing out on GoTo performance).

It would be great to bring the benchmarking programme up to date, and run it. My knowledge of R is basic -- I am a Unix administrator. Would you be able to spend some time working on the program please or do you know any colleagues who would be keen to put some effort in to this?

Regards -- David.

Hello,

I did this bechmark test. Perhaps is it a good oppotunity to rewrite it
and make it compatible with R 2.7.0, David?
Best,

Philippe Grosjean

I wonder if anyone has a more rigorous benchmarking program for R. I downloaded a old R test/benchmarking program (see below), and this didn't work with the current R, and so I wondered if anyone could please direct me to a more recent program that does a good all round test of R.
