similar to: BLAS optimization by CUBLAS

Hi everyone, I have made a faster BLAS library thanks to Nvidia CUBLAS library. I was wondering how I could upload this new Rblas.dll. I've included a powerpoint presentation I made on the project. Highlights include upto 2000% improvement in matrix multiplication timings. Unfortunately the link included in the presentation is only accessible by CSIRO employees only. I will gladly include

Hi, for diagnostic purposes, I would like to get information about the BLAS / LAPACK linked against R from within an R-session. An obvious application could be safety-checks for packages like Matrix and quantreg at load / attach - time. Also you could be more precise on the "framework" in which R is running for comparable benchmark timings on different systems. Perhaps this

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 this. An older version (2.10 I believe) has

One of my packages is slated to be archived from CRAN due to failures when the ATLAS BLAS is used. I am unable to replicate the error on my machine under R 3.6.1 using the atlas library from ubuntu (seems to be 3.10.2-9, while the good professor is using 3.10.3 per https://www.stats.ox.ac.uk/pub/bdr/Rblas/README.txt ). I also tried the rocker/r-base with R 3.6.2 and

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

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,

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) /*********************************************/ /*this

Dear list, What is the recommended incantation on Fedora 32 to swap out the openblas BLAS that the packaged (rpm) version of R-core installs for ATLAS? I'm running into some problems with some big models I want to fit using the mgcv package, and openblas is apparently not thread safe and is causing problems. I have the following installed: $ dnf list installed | grep ^R R-core.x86_64

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

Hi, I tried to compile R-2.10.0 src on 64 bit window. After install Rtools and wingw-w64 compiler and put it the first of my PATH variable, but i got the following error when i tried to compile. Anything I missed? thank you. x86_64-w64-mingw32-gcc -std=gnu99 -I../include -I. -I../extra -DHAVE_CONFIG_H -D R_DLL_BUILD -O3 -Wall -pedantic -DR_ARCH='"x64"' -c malloc.c -o

I think this is not a R-devel question. Sorry to all if I'm wrong, please let me know. I managed to build R successfully with the default BLAS but when I change the MKRULES to use ATLAS BLAS and set the path to "C:/cygwin/home/Administrador/ATLAS/lib/WinNT_ATHLONSSE2" I got the following error message (I'm posting only the final part, there was a lot of compilation before this):

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) loess(z ~ x) does

Hi All, A few years back when I was a CSIRO (an Australian research centre) intern I developed a BLAS package for R that uses the GPU. I believe that there is something similar right now, except it uses a few CuBLAS (Nvidia BLAS) routines, but doesnt replace them. My question is, is it technically illegal to hold back on source code? Thanks, Sachin [[alternative HTML version deleted]]

Of course, even a simpler trick is to launch R as follows: LD_PRELOAD=/lib64/atlas/libsatlas.so.3 R and then the symbols in libsatlas take precedence over libopenblas. Or a mix between both alternatives, i.e., setting LD_PRELOAD=/path/to/some/link R and then change that link to point to openblas, atlas... Whatever suits you best.

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

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

Dear all, Given that the Intel MKL multithreaded BLAS is now free (https://software.intel.com/en-us/mkl/choose-download, released under the very permissive Intel Simplified Software License, https://software.intel.com/en-us/license/intel-simplified-software-license) and that this BLAS comes out as the fastest in most benchmarks, and that Microsoft R Open compiled against Intel MKL seems to be
