Hi R-devel list, OpenBLAS is readily available for unix-likes: https://cloud.r-project.org/web/packages/gcbd/vignettes/gcbd.pdf However, my questions are: 1) Would R-devel consider using OpenBLAS for the main distribution of R for all platforms including Windows? 2) If so, would R-devel set the default multi-thread level to the number of (real) cores on a machine? My sense is there're a lot of wast...

...And always has been. There may have been some license arbitrage: Intel was an early investor in Revo, so MKL was pushed hard. With GotoBLAS and later OpenBLAS I cared less, but IIRC the license of MKL is a little simpler for "mere use" now. See https://cloud.r-project.org/web/packages/gcbd/vignettes/gcbd.pdf for more.

dear debian-R group: I am using the stock ubuntu binary R 3.0.1 for ubuntu raring but on cinnamon mint olivia 15. I read dirk's gcbd paper from a couple of years ago. it suggests that stock blas is pretty bad compared to the four main alternatives. of course, dirk also maintains the binaries for debian/ubuntu R, so he probably knows the answer off hand. I installed libatlas3-base (3.8.4-9ubuntu1) from the software repositor...

Hi I just read the thread on gotoBLAS, as well as the excellent vignette of gcbd. I still have some confusion and would like to ask very basic questions, hope I am not taking too much of your time. The point that retained my attention was the question of using implicit (multi-threaded blas) versus explicit (parallel code) optimisation. As I understood, the ideal would be to...

Dear R Developers, First of all, I would like to thank you Jeroen Ooms for taking the binary Window Builds from Duncan. I firmly believe that the R Community will benefit a lot from his work. However, the debate I would like to open is about if some of Microsoft R Open Code shall be ported from R Open to Mainstream R. There are some beneficts in R Open such as multithreaded performance:

Hi, I'm relatively new to R on Ubuntu (moving from Windows), and I'm trying to get GotoBLAS2 working. I installed (from a CRAN mirror) the pre-built binaries of R (which, as far as I know, is compiled as a shared library) on Ubuntu 10.10 using apt-get install r-base r-base-dev I successfully built GotoBLAS2 from source, copied the library to /usr/lib and created s symbolic link from

...source package like OpenBLAS ? You may be able to switch at will _after_ R has been built and installed. That is something people simply cannot get their head around but lapack and blas are an INTERFACE for which several implementations provide suitable code. That is the gist behind the package gcbd -- which is really a container for a paper / vignette where I use(d) the fact that on a Debian-based system I do have access to several of these (including the MKL) so that I can even script benchmark runs for comparison _from R_ as it is just a (system) package removal / installation which can be...

I've not worked changing underlying computational infrastructure, but developers who do might want to use ideas from FlexiBLAS. Apologies in advance if this is well-known.

Hello, Is there a way to force through R the amount of the cpu's cores (or the cpu's utilization level) used under Windows 7 or Linux? Thanks, Costas

Hello, does anybody know another faster function for random multivariate normal variable simulation? I'm using mvrnorm, but as profiling shows, my algorithm spends approximately 50 % in executing mvrnorm function. Maybe some of you knows much faster function for multivariate normal simulation? I would be very gratefull for advices. -- View this message in context:

Hi all, I have a problem with cpu affinity in my R-2.11.1 installation compiled against ATLAS running on a Linux (Ubuntu 10.04) cluster under GridEngine. I wish to use Grid Engine's core binding feature to bind user processes into the number of cores they request on the cluster, thus preventing badly behaved multi-threaded libraries from consuming more cores than requested. An example of

...ded part of ATLAS. If you want to use the parallelized part, you'll need to add the libpt* libraries by hand. This worked for me: ... also this. Because if you do not deal well with update-alternatives, you loose the plug-and-play of installing and installing BLAS providing packages. For the gcbd package/vignette/paper I hacked together a plugin-package, locally built and hence optmised, but following the Atlas packaging: edd at max:~$ dpkg -f /var/spool/atlas39/libatlas39_3.9.25-1_amd64.deb dpkg -f /var/spool/atlas39/libatlas39_3.9.25-1_amd64.deb Package: libatlas39 Source: atlas39 Vers...
