enhanced BLAS support in R 2.8.1
Hi Josh, Take a look at the section on BLAS in the R Installation and Admin manual. In Linux we've gotten order of magnitude speedups by using GotoBLAS instead of the default BLAS in R. But it's not available for XP - there are other BLAS implementations mentioned in the manual that might be faster than the default, though my guess is that they will not be as fast as GotoBLAS (based in part on an email exchange with Brian Ripley through the R-devel mailing list). -chris ---------------------------------------------------------------------------------------------- Chris Paciorek / Asst.

List, I am running Windows XP and R 2.8.1 on a Dell Core 2 Processor Computer. I have a question concerning the performance speed of matrix operations and BLAS. Is R 2.8.1 already configured to take advantage of more enhanced BLAS than the old standard R BLAS, or is there something extra I have to install or do before I can get to that point? Basically, what I am asking is for any advice on how to speed up these floating point matrix operations, and how R 2.8.1's BLAS plays into that. Thanks. -Josh _______________________________________________ R-sig-Geo mailing list R-sig-Geo at stat.math.ethz.ch https://stat.ethz.ch/mailman/listinfo/r-sig-geo
