Debate: Shall some of Microsoft R Open Code be ported to mainstream R?
I think the thing that is missing is a simple way for end users on windows to replace blas/lapack libraries with MKL-a package that you install that puts the libraries in the right place.
Microsoft provides something for their distro, but we don't have the equivalent if you get R from cran.

GotoBLAS2 breaks lapack
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

parallel BLAS for Ubuntu 11.10
Has anyone succeeded in getting a parallel BLAS, such as Goto's BLAS,
installed on a machine running Ubuntu 11.10?
I currently have the libatlas3gf-base package installed on a machine
with an AMD Athlon X4 processor. I tried to install the
libopenblas-base and libopenblas-dev packages but there seemed to be a
glich related to having both libopenblas and libatlas3gf installed so

BLAS
I'm setting up an Ubuntu?virtual machine?that will use 4-Intel Xeon CPU x5650.?
I'd like to compile R with a BLAS but the question is whcih one.? Seems
like the only free ones are GotoBLAS which I'm not sure is being maintained
for newer CPUs and OpenBLAS for Loongson CPUs.? I saw a favorable report

problems loading blas with R 2.11.0~20100402-1
Hi,
Since upgrading to version 2.11.0~20100402-1, starting R fails with:
/usr/lib64/R/bin/exec/R: error while loading shared libraries: libblas.so.3gf: cannot open shared object file: No such file or directory
Is this occurring to others on sid?

R CMD INSTALL cannot find libf77blas
I feel like Marlon Brando in "On the Waterfront" where he's told "It's

trying to debug memory problems. Now I can't even install an old
version of this package on a netbook running the Ubuntu 10.10 netbook
remix because it can't find the libraries libf77blas and libatlas.

stock ubuntu raring binary R 3.0.1 and accelerated blas libraries?
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

Heads up - symlinked GotoBLAS in F14
Hi,
I installed F14 on release, but was diquieted to note that my symlinked
GotoBLAS (http://cran.r-project.org/doc/manuals/R-admin.html#Shared-BLAS,
foot of paragraph) prevented R (compiled from source, no special configure
options) from loading - everything had been fine on F < 14. It seems that:
cat /selinux/booleans/allow_execstack
is 1 1 on my RHEL systems, but became (?) 0 0 in F14.

Can you share a working example of R program aided by fast BLAS?
Can one of you give me an R program that displays the benefits an
accelerated BLAS in R?
Here's why I ask, in case you wonder:
In a linux cluster, I've hit some bumps in the road. The worst one by
far was that I installed R, then GotoBLAS2 with default settings, and
after that, jobs using Rmpi were *really* *really* slow. I mean
horrible. If a job took 15 minutes when run by itself,

LAPACK lib problem, lme4, lastest R, Linux
I just dumped Vista off a laptop and installed Ubuntu 10.10 (latest
release) as the single operating system. I did all of the updates and
then installed emacs and ess. Next I installed R by following the the
usual instructions on the CRAN site. At this point all is working I am
now in the process of installing the packages that I normally have
installed. I am having a problem with the LAPACK

LAPACK libraries improperly linked
I am not sure if this is an R development problem or not. I am starting
with completely clean OS and and installing the latest version of R
without trying to anything special but I am having trouble with the
LAPACK library linking when I try to build packages that require them.
I thought perhaps my problem may be if interest here.

How to verify R is running with multi-threads
Hi all,
I've compiled R (version 2.8.1) from the source code with "--with-
blas=" option in order to use external multi-threaded blas package.
However, it's very hard to verify that compilation is correct and R is
using multi-threads correctly or not. Which command or operation in R
will run with multi-threads?
I assumed that matrix multiplication %*% may call multi-threaded

Optimize R: some confusion with Lapack and OpenBlas/openBlas openmp packages.
I run Fedora 22 R package. It is build with --with-lapack \
--with-blas \ --enable-R-shlib \.
As the machine will act as a server with lots of R data computing, I
try to optimize my R package.
At first, I installed parallel_studio_xe_2016 with a free one year
licence. Then, I build a package for R with Intel MKL and compiler.
This took me lots of time as it was my first .rmp build. I finally

config.log told me to report these (PR#12035)
Hello r-bugs,
I am running openSuse 11.0, with my new Intel 8500 (Penryn) C2D, and I want to use icc and ifort.
I was able to get a working Goto BLAS, following Dr. Goto's instructions.
That seems to work OK with gcc and gfortran.
I get about 10% faster computations by using -O3 rather than -O2.
I get faster results with Goto BLAS rather than the R BLAS.
Now I want to make icc and ifort

Debate: Shall some of Microsoft R Open Code be ported to mainstream R?
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:
