Dear Windows Maintainers, after installing R 2.6.0 on Windows 2000 and doing a complete update of the libraries as recommended by B.Ripley, it get the error message: The dynamic link library Rblas could not be found in the specified path.... Note that the message says "Rblas", not Rblas.dll as expected under Windows. The path is correct, and Rblas.dll is present I made a copy of Rblas.dll in \bin naming it Rblas, and got it to work. I post this here since I don't know if th...

I encountered the following problem in R-2.4.0 for Windows binary downloaded from CRAN (data from R-help post by Ethan Johnsons). I was also using the contributed binary Rblas.dll for Intel P4 chip. The problem doesn't occur with the default Rblas.dll. x=c(3.05176E-05, 0.000457764, 0.003204346, 0.0138855, 0.04165649, 0.09164429, 0.1527405, 0.1963806, 0.1963806, 0.1527405, 0.09164429, 0.04165649, 0.0138855, 0.003204346, 0.000457764, 3.05176E-05) y=c(0.0000306, 0.0...

hi everyone, Im implementing a new RBlas dll but just for optimising sake i need to know how and WHERE (which source code) RBlas gets loaded. there is a call to loadlibrary() in dynload.c BUT it seems this is not the function that is loading Rblas. how do i know this? well i added the code :(just after the loadlibrary() call) /*...

I noticed a problem using R 2.7.1 on Windows XP SP2 with the precompiled Atlas Rblas.dll. Running the code below causes R to crash. I started R using Rgui --vanilla and am using the precompiled Atlas Rblas.dll from cran.fhcrc.org dated 17-Jul-2007 05:04 for Core2 Duo. The code that causes the crash: x <- rnorm(100) y <- rnorm(100) z <- rnorm(100) loess(z ~ x * y) loes...

Ok, moved to R-devel. I tried to build R-2.3.1. Since I intent to distribute this tuned R to all other who have a computer like mine here at work I thought it was best to stay with the latest stable release. About your suggestion, I could'n find xerblas.o file. And I don't know how to edit libf77blas.a. I tried to open it with VIM (http://vim.sf.net/) but there was a lot of strange symbols (expected, I think), either way I found a reference to xerblas.o inside it but didn't know what to do with this reference. Thanks, Giuseppe Antonaci On...

There is a new area on CRAN bin/windows/contrib/ATLAS which contains Rblas's compiled against ATLAS 3.4.1 for various chips. To use one of these, just rename rw1051\bin\Rblas.dll and drop the replacment in its place. Using a tuned BLAS will be noticeably faster only on some linear-algebra calculations, notably those using La.svd and La.eigen (which might be twice as...

...for comparable benchmark timings on different systems. Perhaps this information may even be included into the output of R.Version() :-) ? So my question: Is this possible/reasonable at all? My impression is that it is not trivial, as you may ---at least on Win32--- even replace the standard Rblas.dll by some of the "better" Rblas.dll 's available on http://cran.at.r-project.org/bin/windows/contrib/ATLAS/ without telling R in any way before launching R. In the (Win32) case I imagine you could read out the StringFileInfo of the Rblas.dll being used --- which, for t...

Does anybody have a tuned Rblas.dll compiled against ALTLAS for a dual Xeon system? Unfortunately, we have very strict security that does not allow compilers of any sort on production desktops - we only have Pentium III development PCs.

Dear all, when making a DLL via Rcmd SHLIB is there a way to link against a library such as Rblas (I am on a Windows platform) on a case to case basis? I played a bit around with some self-written C-code which should call the function 'dasum' defined in Blas.h. I encountered the following problem: u:\codeplay>Rcmd SHLIB mysumming.c Rcmd SHLIB mysumming.c gcc --shared -s -o mysum...

Dear colleagues! In early 2009 there was a discussion about fast BLAS library initiated by Sachin. He reported a faster BLAS library made by Nvidia CUBLAS library. Uwe Ligges showed an interest for placing the optimized rblas.dll into windows/contrib section managed by him. Unfortunately there is no any CUBLAS version of rblas.dll in this section at present. So, is anybody interested in CUBLAS optimization of rblas now? In my opinion current directions (packages) of high-performance and parallel computing with R suff...

Hi, In rw-FAQ, there is a paragraph about optimizing R by using a fast ATLAS library in place of the standard BLAS. It says: "BLAS support is supplied by the single DLL `R_HOME\bin\Rblas.dll', and you can add a fast BLAS just by replacing that." Do I need to recompile the whole R with the option `USE_ATLAS = YES', or is it possible to compile only Rblas.dll on each separate computer (with different processors)? Thanks, Philippe Grosjean ...........]<(({?<.........

Good afternoon. I am trying to compile a version of Rblas.dll based on ATLAS for the Corei7. I had remembered that there was mention of which file to adjust and that "xerbla" needed to be removed from one of the outputs from the last time I tried a few years ago. The most recent version of the R Installation manual does not say anything about th...
