...; 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.

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

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,

Hi, I have built R (current development version) and BioConductor 1.7 with portland group compiler on a AMD Opteron. When I ran qc assessment on Affymetrix latin square data set, I got the following output, Loading required package: affy Loading required package: Biobase Loading required package: tools Welcome to Bioconductor Vignettes contain introductory material. To view,

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

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

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

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

Hi, I"m a newbie on building R on Windows. I followed the instructions cited here, http://www.murdoch-sutherland.com/Rtools/ to build R-2.2.0. Everything works fine up till when package base needs to be compiled. here is the error message, ---------- Making package base ------------ adding build stamp to DESCRIPTION Error in library.dynam(lib, package, package.lib) : shared

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

Hi, I'm not sure if this question has been answered before, but when I execute command "Rcmd INSTALL --build nws" to build an R package on Windows, the build process got stucked on the save image step. Here is the snapshot of the build process, --- Making package nws ---- adding build stamp to DESCRIPTION installing NAMESPACE file and metadata installing R files

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/bin/pgcc CFLAGS='-g -O2' CPPFLAGS='-I/usr/pgi/linux86-64/6.0/include
