I try to install RScaLAPACK on Ubuntu 6.10 and LAM 7.0.x Does anybody know a useful link top some how-to site about RScaLAPACK. Now I manage to get the package compiling, but the linker shows me lots of unsolved references: sudo R CMD INSTALL RScaLAPACK_0.5.1.tar.gz --configure-args="--with-mpi=/usr/lib/lam": *...

Hi all, I'm using RScalapack library for parallelizing some heavy matrix operations required by MCMC methods for spatio-temporal models. The package reference manuals (dated 2005) states that the library needs LamMPI to work but we have a Linux Cluster with OpenMPI. We have found (http://cvs.fedoraproject.org/viewvc/devel/R-RS...

I have Windows XP Professional Version 2002 and the R-Version 2.1.1. I want to do factor analysis with R. In Google Search I find the reference to the RScaLAPACK-Package, but my R-Version 2.1.1. told me that "RScaLAPACK is invalid package, bevor 2.0.0. installed" . Which package can I take for factor analysis? [[alternative HTML version deleted]]

...e: A. Snow (with Rmpi or Rpvm) (as described in http://www.r-project.org/useR-2006/Slides/Harrington+Salibian-Barrera.pd f from the 2006 R User Conference) It is my understanding that this approach is viable, and works with OpenMPI 1.2.4. Is anyone using this method with good results? B. taskpR, RScaLAPACK, pMatrix I read a paper http://sdm.lbl.gov/sdmcenter/projects/SDM.center.parallel.r.2-pager.4.do c coming out of the ORNL, describing what they call "parallel R", which included taskpr, RScaLAPACK, pMatrix. I notice that taskpR is no longer available in "contrib", nor is pMatri...

Hi, I had access to an hpc cluster, and wanted to parallelize some of my R code. I looked at the snow,nws, rscalapack documentation but was unable to make out how I should submit my job to the hpc, and how I should code a simple program. For example, if I had 10 matrices, and 10 processor how should I write the R (and the hpc submit code) so that I run the calculations (e.g. rowsums) for each matrix in a different...

Dear R-help, Has anyone tried running R on a Beowulf-type cluster? I can get R to run in batch (using R CMD BATCH) on a cluster, but am wondering if it is possible to get an interactive R session on a compute node. Right now, if I run: beorun --nolocal R I just get the R start-up message and back to the shell prompt. If I try bpsh 0 R I can get R started (but the R prompt does not

Hello, I have a matrix equation, Ax=b, that I need to solve for x. x should be a vector of positive numbers (between 0 and 1). A is not a square matrix in general. This lead me to using the SVD. However, using the SVD gives me positive and negative numbers, as well. I have some constraints included in the A matrix itself (i.e., that the sum of some xi should be equal to 1) but I do not know how

A while ago I decided to simply download and install every package on CRAN (disk space is cheap these days...). In the process, I kept loose track of which packages generated one or more 'compilation errors' during the install process (machine runs 64-bit Fedora 8, gcc 4.1 etc. etc). Most of the errors seemed to occur in packages I have little need for at present, but as a courtesy, I

Hi All, I'm still having significantly difficulty getting the quantreg library running in R. I'm running R on MEPIS using the debs created by Dirk Eddelbuettel and placed in apt testing. When I try to install quantreg using the install.packages() function it fails with: /usr/bin/ld: cannot find -lblas-3 Dirk was nice enough to send me a .deb for quantreg which installs without

Hi, everybody. I've got some Centos Linux systems and some Ubuntu Linux systems. R's basically the same in either place, but the packaging of R for Debian systems seems better to me than it is on Fedora/Redhat/Centos. I joined R-sig-debian and we talk about package management issues there sometimes. One of the really handy R packaging ideas they have is to customize R environment so

Dear R-dev, I would like to accelerate my R computation by using parallel OpenMP compilers (e.g from Pathscale) on a 2-processor AMD server and I would like to know whether R is a tread safe library. The main kernel of the OpenMP parallelization is a C SEXP function that performs the computational routine in parallel with: ******************* SEXP example(SEXP list, SEXP expr, SEXP rho) {
