I am encountering segfaults when checking the lme4 package on an Athlon64 system if I use the acml blas. R was built as a 64-bit application using the GCC 4.0.3 compiler suite including gfortran. The version of acml is 3.5.0 gfortran64. I do not encounter the segfaults when I compile R with R's built-in BLAS. The errors occur in the first example in lme4 in a call to lmer. It looks like t...

Greetings - I'm trying to compile R under GNU/Linux (RHEL 4) on a multi-Opteron box, with ACML support. First, I downloaded and installed ACML 3.5 - GNU version, although I'm not entirely sure what the differences are - from the AMD website. The ACML libraries were installed to /opt/acml3.5.0/ Second, I ran ./configure --with-blas='-lacml' The configure went fine, exce...

I am trying to get R to use the ACML BLAS, specifically the 'mp' version for multithreading. I have installed acml-4-4-0-gfortran-64bit I added /opt/acml4.4.0/gfortran64_mp/lib to $LD_LIBRARY_PATH. I ran: sudo ./configure --with-blas="-L/opt/acml4.4.0/gfortran64_mp/lib -lacml_mp" At the end of the configuration...

I'm trying to build R-devel with AMD's ACML. I downloaded version 3.0.0 64bit for gfortran (acml-3-0-0-gfortran-64bit.tgz) and copied the libraries to /usr/local/lib. When I configure R to build against the ACML library, how do I know if the library has been detected and will be used? I run 'configure' with the '--with-bla...

While I recently received some very helpful files and email from Kevin Hendricks for compiling with ATLAS, thought I'd first have a stab at ACML. Having problems, which I suspect are trivial to solve: 1. machine is running RHEL 4, meaning, it uses gcc 3.4.5 out of the box, and g77. In my experience, over-riding RHEL's choice, and manually upgrading to gcc 4.x.x (and, as a consequence gfortran) will cause problems in other areas (but...

dear experts I'd like to ask you, probably on behalf all of us who try to use AMD's ACML for performance optimisation a question. There seem to be problem when these two, R and ACML are coupled, described here: http://devgurus.amd.com/message/1255852#1255852 I'd like to ask, while not being a programmer/developer, how incorrect and dangerous this might be? maybe such a setup mu...

...to move to a distro with longer 'term-of-life' than the release schedule for Fedora currently allows. The machine is a multi-Opteron box, so both 32- and 64-bit apps natively supported. Since I do a lot of 'linear algebra'-heavy things with R, I had compiled R 2.9.0 against the ACML blas. ACML contains lapack, so I killed two birds with one stone. Generally, I would do a configure with ./configure --with-tcltk --with-blas="-L/opt/acml4.3.0/gfortran64/lib -lacml" Worked perfectly. Led to 10-20x speedup in certain calculations. Things haven't been so good si...

Hi, Has anyone had any luck in using portland group compiler to build R(-devel) with AMD's pgi compiled ACML library? I've downloaded the packages and set LD_LIBRARY_PATH, and run configuration script as follow: % ./configure --prefix=/usr/local/R.pgcc --with-blas='-lacml' However, it failed to pick up double complex BLAS, checking for sgemm_ in -lacml... yes checking whether double comple...

I've been updating the information on tuned BLAS for R-admin in R-patched and R-devel. We have ATLAS (widely available, including for Windows) MKL (licensed on ix86 and x86_64 Linux and Windows) ACML (by AMD, but for all ix86 and x86_64 chips, Linux and Windows. Now available for gfortran.) Goto (academic use only, only some chips, only Linux) MKL and ACML provide full LAPACK, the other two some optimized LAPACK routines. (We have an MKL licence with our icc/ifort licences but it h...

For grins, tried rebuilding R 2.9.0 without using ACML 4.3.0. Config goes fine, make runs without any errors. make check - and - ta-dah! - no errors for stats. Everything seems to check out just fine. So, it seems as if R 2.9.0, ACML 4.3.0, and perhaps one/more things under CentOS don't play nice. Will trying unloading 4.3.0, installing 4.2.0...

Greetings - For a host of reasons I chose (was forced) to upgrade my multi-Opteron box from Fedora 7 -> Fedora 8. In the process, I also updated the ACML I had installed from 4.0.0 to 4.1.0. While I get no errors (that I can find) in the config -> make -> make install sequence, I'm pretty sure (based on some benchmarks) that I'm not getting BLAS and/or Lapack to compile in. So, either something has changed from 2.6.2 -> 2.7.0, or s...

So, tried again from scratch. Again, CentOS 5.3, which is essentially RHEL 5.3. ./configure --with-blas="-L/opt/acml4.3.0/gfortran64/lib -lacml" In config.log, get things like configure:37199: checking for dgemm_ in -L/opt/acml4.3.0/gfortran64/lib -lacml configure:37230: gcc -std=gnu99 -o conftest -g -O2 -I/usr/local/include -L/usr/local/lib64 conftest.c -L/opt/acml4.3.0/gfortran64/lib -lacml -$ conf...

Normally, I do the following to configure R for compilation on my Opteron box with ACML installed: ./configure --with-tcltk --with-blas="-L/opt/acml4.3.0/gfortran64/lib -lacml" However, when I do so, and look at Makeconf, I see BLAS_LIBS = -lblas I thought I would see BLAS_LIBS = -L/opt/acml4.3.0/gfortran64/lib -lacml Why isn't Makeconf picking up the right BLAS_L...

Have been running 2.5.1 on my multi-pro Opteron box running Fedora Core 5 with no problems. Had compiled previously with no problems. However, for a variety of reasons (mostly due to ACML upgrade), I tried a recompile using the following sequence of commands (note I'm compiling in ACML support for blas): LD_LIBRARY_PATH=/opt/acml3.6.1/gfortran64/lib export LD_LIBRARY_PATH ./configure --with-lapack --with-blas="-L/opt/acml3.6.0/gfortran64/lib -lacml" This is ex...

Dear R-devel, Has anyone played with this? http://www.amd.com/us-en/Processors/DevelopWithAMD/0,,30_2252_2282,00.html <http://www.amd.com/us-en/Processors/DevelopWithAMD/0,,30_2252_2282,00.html> .

Hi, I'm following up to a post I made to r-help here: http://r.789695.n4.nabble.com/Trouble-configuring-R-to-use-ACML-tt2337193.html#a2337193 I have verified that LD_LIBRARY_PATH is set... I set it in /etc/bash.bashrc (is that ok?) and it shows up when I echo $LD_LIBRARY_PATH I also tried adding the paths to the ld.so cache as Prof Ripley had suggested. I get the same results when running configure. So after th...

...m like this. So, I dig a bit deeper. Most of the jobs we want to run could benefit from BLAS support (lots of array manipulations and other bits of linear algebra), and a few other compilation optimizations - and here is where I seek advice. 1) Looks like there are 3-4 flavours: LAPACK, ATLAS, ACML (AMD-chips...), and Goto. In reading what I can find, it seems that there are reasons not to use ACML (single-thread) despite the AMD chips, reasons to avoid ATLAS (some hassles compiling on RHEL 4 boxes), reasons to avoid LAPACK (ibid), but apparently no problems with Goto BLAS. Is that a rea...

I have problems building R 2.11.1 with an external BLAS. I've tried several with several libraries: # ACML: export LD_LIBRARY_PATH=/site/VERSIONS/acml-3.6.0/gfortran64_int64/lib BLAS=--with-blas="-L/site/VERSIONS/acml-3.6.0/gfortran64_int64/lib -lacml" LAPACK=--with-lapack # MKL 11: BLAS=--with-blas="-L/site/VERSIONS/intel-11.1/mkl/lib/em64t -lmkl_gf_lp64 -lmkl_sequential -lmkl_lapack -l...

Hi, I'm having problems using ACML with R. I made two changes in config.site by setting LDFLAGS="-L/opt/acml3.1.0/gnu64/lib" BLAS_LIBS="-lacml" ./config and make go through but when I try to use the lm() function, I get the error message Error in chol2inv(Qr$qr[p1, p1, drop = FALSE]) : lapack routines c...
