Viable Approach to Parallel R?
...; I see that SCAI (Scientific Computing Associates) offers a parallel R package based on something they call NetworkSpaces and "Sleigh" (inspired by Snow). They sell services around the product but it is open source. They have an enhanced version that they sell & support. http://www.lindaspaces.com/hp/BenchmarksWithCharts.pdf. Has anyone investigated this approach or it's open source components? TIA for any information, direction, suggestions, and if I've missed any other approaches please advise.

build R with Visual Studio
Hi, Has anyone had success in building R source with Visual Studio? I followed the instructions in README.packages, but failed on the very first step, where it's looking for R.dll. I looked through R source and couldn't find the file. Can someone point me to where this file is located or generated? Thanks! Sincerely, Jennifer

Build Portland Group Compiler
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. If you meant to cross compile, use `--host'. See `config.log' for more details. so I tried to set host=x86_64-unknown-linux-gnu,

Build R with AMD pgi compiled ACML library
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

complex.h in R
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, /usr/lib64. PGI said they don't support complex.h. R configuration script printed out that doublecomplex is

FFT
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 memory (2 GB RAM) than 1.8 GHz (1 GB RAM). The only difference is that 1.8 GHz is a dual-processor

additional comments on building R with PGI compiler
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='-L/usr/lib64 -lg2c -lblas' # for generic BLAS library that comes

performance of nchar
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 1:10000) + str = sprintf('0005%020d', nchar(op)) + )[3] [1] 0.7 Experiment 2, get the length of op separately using nchar, and then pass
