Hi Uwe Liqqes, Does the successful compilation for R-1.9.1 on AIX 5.1 depend on the IBM AIX compiler for C and C++ (xlc/xlC)? gcc on AIX is not compatible with R1.9.1.

Hi your guys, Recently, I installed R-1.9.1 on AIX 5.2 with 64 bits environment; I already have following software installed on AIX before I compile R-1.9.1 source codes: g++ 2.9.aix51.020209-4 The GNU C++ compiler and headers gcc 2.9.aix51.020209-4 The GNU gcc C compiler and headers xlf XL Fortran for AIX perl 5.6.1-2 zlib 1.1.3-10 For latex and makeinfo stuffs, I have

Dear R Users, I compiled two R-1.9.1 environments on IBM P690 AIX platform, one with optimization level 3(-O3), another with optimization level 2(-O). I would like to do some performance comparison with these two environments. Can anybody give me some advices for how to do the performance test against R? Thanks in advance. Kexiao

Dear R Development Team, I compile R-1.9.1 on AIX 5.2 under 2.9-aix51-020209, and xlf 7.1. In order to let R compile successfully under gcc 2.9, I have to change one C statement of file(RHOME//src/modules/X11/devX11.c) line 1768 from "retrun FALSE" to "retrun NULL", following is C code snapshot: newX11Desc * Rf_allocNewX11DeviceDesc(double ps) { newX11Desc *xd;

Hi Paul, I use executable codes of tex and latex from http://aixpdslib.seas.ucla.edu/packages/tetex.html) and compile the original R-1.9.1 source codes using C for AIX compiler V6.0 and Fortran for AIX compiler 7.1.1 and generate 64 bit R environments. It works well. Kexiao -----Original Message----- From: Paul Murrell [mailto:p.murrell at auckland.ac.nz] Sent: Monday, August 02, 2004 6:10

All, We are researching approaches to parallel R with the end goal of running R in a distributed manner on a Linux cluster. We expect of course to do some work decomposing our problems to be task-parallel or data-parallel, but wouldn't mind getting an initial boost working with "embarrassingly parallel" code sections and one of the approaches below. Incidentally our environment

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

OK, my journey to make lab machines automagically install & update all desirable R packages is nearing an end! The only question I have now is this: How can I control where the system prints the *.Rout file that is created automatically when the R batch program runs. In "man R" I don't find any information about it. When the cron job runs "R_installAll.sh" (see

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

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

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]]

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-RScaLAPACK/) a patch for OpenMPI but we are wondering if in the

Dear R Development Team, I just compile R-1.9.1 on AIX 5.2 using gcc 2.9-aix51-020209. During the compile process, there is an error message saying "return type mismatch in R_HOME/src/modules/X11/devX11.c line 1768. Following is the part of the C codes from file devX11.c /** This allocates an newX11Desc instance and sets its default values. */ newX11Desc *

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) {

Dear R users, I have access to a Sun cluster with multiple processors , a lot of RAM and with RedHat installed. I want to take advantage of its power for a R routine very time consuming. Whick package do I have to use? I know there are snow,snowFT and others package.Which is the best for my purpose? Do someone have experiences with this? Thanck in advance. Moreno

Hello, I am trying to do some parallel programming with R. I programmed with C and MPI before. I heard that there is a package called Rmpi and one called snow. What is the difference? I know the administrator installed snow in our system so I wonder if this mean there is Rmpi in it. I believe the Rmpi will have similar functions than MPI that is why I am specially interested in it. Thanks

After several trial and error attempts, I managed to install the Rmpi package without error on my Linux machine, running Fedora 5. I installed lam-7.1.2, lam-devel-7.1.2 and R-2.4.1, R-devel-2.4.1 The Package Rmpi_5.0-3.tar.gz, I installed once from within R and once from the command line to make sure, I link the right libraries: R CMD INSTALL Rmpi_5.0-3.tar.gz

Has anybody tried to use Rmpi with the OpenMPI library instead of LAM/MPI? LAM appears to be somewhat hardcoded in the Rmpi setup. Before I start to experiment with changing this, has anybody else tried Rmpi with non-LAM MPI implementations?

Hello, I've installed R on my RHEL3 cluster and I am trying to get Rmpi to work properly. R is installed using the following ./configure --prefix=/home/apps/R-2.2.0 I installed snow using R CMD INSTALL /home/apps/snow And finaly Rmpi R CMD INSTALL /home/apps/Rmpi --configure-args=--with-mpi=/path/to/lam There were no errors or warnings upon installation.
