Hi,
Is nchar function knowingly slow in R? I'm doing some string
formatting that requires multiple call to nchar, and nchar seems to be
very slow.
Experiment 1, pass nchar inside sprintf, and it takes 0.7 seconds
> system.time(for (i in 1:1)
+ str = sprintf('0005%020d', nchar(op))
+ )[3

Hi,
I"m a newbie on building R on Windows. I followed the instructions

Hi,
I have additional comments on building R with PGI compiler.
If one wants to use external BLAS library, then pgf90 instead of pgf77
should be used, and BLAS_LIBS flags should be set.
e.g.
F77 = $PG_HOME/bin/pgf90
BLAS_LIBS='-L/opt/acml2.7.0/pgi64/ -lacml' # for ACML library
BLAS_LIBS='
Hi,
Is FFT implemented in R takes advantage of multi-processors?
I ran this benchmark from from http://www.sciviews.org, and AMD Opteron
2.2 GHz performs better than AMD Opteron 1.8 GHz on all test cases,
except FFT operation.
Both machines run same OSs (RedHat WS 3) and 2.2 GHz has more memo

Is there other thing I should look into in the config.log?
Your help is very much appreicated.

Hi,
How does complex.h used in R? Whether a compiler support complex.h
or not, does it affect R's performance? I used PGI compiler to build
R-devel on AMD Opteron, but the configuration file failed to link BLAS
library despite the fact it is located in the usual location,

If you meant to cross compile, use `--host'.

Hi,
I built R with Portland Group compiler, but I noticed one thing that
when I ran configure for the first time on AMD machine, I got the
following error:
checking whether the C compiler works... configure: error: cannot run C
compiled programs.

I downloaded R-devel and compiled it with pgcc. This time, instead of
breaking in src/main, compilation breaks in src/modules with the
following error messages.

Hi,
Can anyone advise me on how to compile R with Portland Group
compiler on a Opeteron machine with Red Hat Enterprise Linux WS release
4 installed?
I've edit config.site file to pick portland group compilers instead of
gcc. Here is the list of modified flags:
CC=/usr/pgi/linux86-64/6.0/bi
