Hello. I am a Linux neophyte and know almost nothing ?about compiling, so I would appreciate any help and advice y'all would care to offer. I am trying to compile the 64 bit version of R using a tuned ATLAS and LAPACK (ATLAS 3.9.24). I am running Ubunto 10.04 LTS (through wubi, FWIW). The ATLAS and LAPACK files (atlas.so, f77blas.so, lapack.so, and cblas.so) are sitting in the folder

hello, everybody, I met a problem that I want to generate a random uniform number by using function with c interface. What I found is only "unif_rand()", but its range is [0,1]. How can I create a uniform random variable by using a function with c interface. Who can tell me what function it is and how to use? I will appreciate for it very much. Thanks in advance! xiaotong wang

I don't see why the Debian shared libraries shouldn't work, but it's not too hard to make shared ATLAS: first you need to get the flags for position-independent code (-fPIC on gcc) into the compilations, which can be done in the "config" program (add it to the defaults for the C and Fortran compiler flags), then you extract the object files from the .a archive built by

Hello, everybody, I created a R package which includes C code. But I load this package, and carry out the R function in it. It shows C function is not in load table as follows. Would you tell me what is the problem? Where do I make mistake? Maggie [Previously saved workspace restored] > library(var) Attaching package 'var': The following object(s) are masked _by_

Hi, I'm trying to follow the R-admin instructions for using MKL10 as the external BLAS compiling R-2.6.2 under Linux on a RH EL head node of a cluster. The configure process seems to have problems when it checks for dgemm in the BLAS. I'm using configure as: ./configure CC=icc F77=ifort --with-lapack="$MKL" --with-blas="$MKL" where $MKL is defined as in R-admin

Hello, everybody, I met a big problem. What I want is to use c code in R. I have load a test code "conv.c" in R and run it successfully. However, in my real code, I use matlab c library (Matrix Inverse function). After I use command "R CMD SHLIB" to share library, I can not use "dyn.load" to load the object in R. "undefined symbol:

I believe that actually means configure was able to use the BLAS you specified (MKL in this case). You can scan through config.log to make sure.

hello, I create a package which includes C code and Lapack. But when I run " R CMD check ". an error message, "/usr/bin/ld: cannot find -lfrtbegin " occurs. could you tell me what is the problem? the detailed message is as follows: [credsim@confsys ~/src]$ R CMD check var * checking for working latex ...

Hello, all, I have the same question as the last mail I sent. I have installed libRmath in my system. But I still can not link Rmath through -lRmath. The whole process is as follow.Is there anybody who is so kind to help me find out the problem? I will appreciate very much.

hello, I have a c code which uses clapack. I want to integrate R with this code. It said that I create a R package including my c code. Then build it with putting PKG_LIBS = $(LAPACK_LIBS). I want to know the interface LAPACK_LIBS is Fortran or C? If it is written in Fortran, how can I build them together? If I can build them together, I still use the function in cLapack or the function in

Hello, I can't link a c code with Mathlib according to introduction of R manual "Writing R Extensions", page 60. It is written : "It is possible to build Mathlib, the R set of mathematical functions documented in 'Rmath.h?, as a standalone library 'libRmath? under Unix and Windows. (This includes the functions documented in Section 5.7 [Numerical analysis

Hello all, A colleague at work set me the challenge to convert some MATLAB code into R, to see which is faster. We'd seen that benchmark comparing MATLAB 6.5 to R1.90 (and others), and so I thought that I should be able to get roughly comparable speeds. The code has lots of multiplications of matrixes, transposes, and MATLAB's "repmat". I did the code conversion, and R was about

Dirk suggested I move this thread over here. I am trying to get a multithreaded (multi CPU) version of ATLAS working with R, and have been unable, thus far, to get it working. Has anyone gotten an multithreaded version of ATLAS working on Debian (64 bit)? I've tried this: apt-get source atlas -t unstable cd atlas-3.8.3 DEFAULTS=n fakeroot debian/rules custom but it is APPEARING to only

Rhelpers: I recently installed the 64-bit version of R on my Debian system, and afterwards was asked if it was compiled using ATLAS. Is there a way to test to see if R is using ATLAS? --j

Hello. I know almost nothing about Linux, so I apologize if the answer to this is obvious. I am trying to compile R with ATLAS (successfully compiled 3.9.24 on Ubuntu 10.04 64 bit). I configured with: ./configure --enable-R-shlib --enable-BLAS-shlib --with-blas="-L/usr/local/atlas/lib -lf77blas -latlas" --with-lapack="-L/usr/local/atlaslib -llapack -lcblas" --with-x and I

Dear R-devel: The Cluster administrators at KU got enthusiastic about testing R-3.2.2 with Intel MKL when I asked for some BLAS integration. Below I forward a performance report, which is encouraging, and thought you would like to know the numbers. Appears to my untrained eye there are some extraordinary speedups on Cholesky decomposition, determinants, and matrix inversion. They had

Hi all, I just cloned from git clone https://git.centos.org/git/rpms/atlas And rpmbuild is failing with error in building ATLAS:- make[1]: Leaving directory `/home/sudhanshu/rpmbuild/BUILD/ATLAS/x86_64_base' DONE configure + '[' base = base ']' + sed -i 's#ARCH =.*#ARCH = P4E64SSE3#' Make.inc + sed -i s#-DATL_AVX## Make.inc + sed -i s#-mavx#-msse3# Make.inc + echo
