PVM error message
Hello R enthusiasts,
I am working with a Fedora Core 6 OS and R 2.5. I have just finished
loading PVM on my test cluster and this is working properly. Also, rpvm
has been loaded in R. However, when I try to load my test program, I
receive this error:
Loading required package: rpvm
Error in dyn.load(x, as.logical(local), as.logical(now)) ;

Problems with snow and rpvm
Dear Friends,
I'm trying to learn to use parallel computation using
snow & rpvm
Now, I have two boxes:
1) Pentium 4, pvm 3.4.5, R 2.2.0
with FreeBSD 5.4 (box uffbsd);
2) PowerPC, pvm 3.4.5, R 2.1.1 with
Debian Linux latest stable (box powerpclinux);
I'm using the
instructions in (found in snow.pdf) http://www.stat.uiowa.

rpvm/snow packages on a cluster with dual-processor machines
Hi,
does anybody know how to use the dual processors in the machines of a cluster? I am using R with rpvm and snow packages. I usually start pvm daemon and add host machines first, and then run R to start my computing work. But I find that only one processor in each machine is used in this way and the other one always stays idle. Is there any simple way to tell pvm to use the two processors at

sharing experience - installing R Spatial Views
Hi Guys,
I would like to share my experience when installing the Spatial views
packages for R. I could not install 32 packages which are parts of the
Spatial views, and I use google-search and search to solve ALL those
problems for about 2 days. I hope maybe somebody would benefit from my
experience.
I admitted that I do not have excellent programming skills at all. So,

rpvm/snow packages on a cluster with dual-processor machi nes
Caveat: I've only played with this a couple of years ago...
I believe you can just add each host _twice_ (or as many times as the number
of CPUs at that host) to get both CPUs to work.

Erlang-style message-passing in R: Rmpi, Snow, NetWorkSpaces, etc.
I see about 7 different R packages for multi-process parallel
programming. Which do you think is the best, most complete, and most
robust to pick for general purpose Erlang-style message-passing
programming in R, and why?
First here's my use case, and then my analysis so far. I often have
code whose basic organization looks something like this:

build rpvm under cygwin
I tried ot build rpvm in my own makefile.
But runs into some linker errors like e.g.
undefined reference to `_R_alloc'
My enviornment looks like this:

pvm 3.4 compiled under cygwin myself
R installed from the rw2001.exe setup file.
I guess that the R under rw2001.exe was build with
some other compiler?
I then tried to compile R myself under CYGWIN but runs

rpvm arch check
I've trying to fix the check error in rpvm package. Right now on my Mac, I
use darwinport to install PVM and I can get rpvm to pass the check using 'R
-arch x86_64 CMD check'. However the default 'R CMD check' uses i386 which
fails since PVM is built for x86_64 only.
So is there a way to ensure proper architecture is used that matches that
of the external library like PVM?

Announcing snowFT 0.1
Parallel programming with snowFT
Our package snowFT is now available at CRAN. It is an extention of the
package snow, which adds fault tolerance (in the sense of recomputing
computational units when hardware/network failures occur on compute
nodes) and a tighter notion of reproducibility for computations
running on clusters. It additionally provides tools for flexible
management of cluster size

SNOW: Simple Parallel Computing in R
The package `snow' (Simple Network of Workstations), originally
announced in early form about a year ago on this list, is now
available from CRAN. Snow implements a simple mechanism for using a
workstation cluster for ``embarrassingly parallel'' computations in R.
The interface, which is based in part on the Python CoW (Cluster of
Workstations; http://www.scipy.org/) package, is

question about Rpvm, SNOW, etc.
Dear R-devel,
Inspired by Michael Li's talk at JSM, I decided to try rpvm and snow on our
two linux boxes. It only took me a couple of hours of screwing around to
get it working (sooner if I had RTFM).
Our setup is: 2 dual PIII-866 Xeons, one with 2GB RDRAM, the other with
1.28GB RDRAM. The first machine is acting as the NIS/NFS server. both /usr
and /home are exported to the second

How to utilise dual cores and multi-processors on WinXP
Hello,
I have a question that I was wondering if anyone had a fairly straightforward answer to: what is the quickest and easiest way to take advantage of the extra cores / processors that are now commonplace on modern machines? And how do I do that in Windows?
I realise that this is a complex question that is not answered easily, so let me refine it some more. The type of scripts that I'm

rpvm for windows anyone ?
Dear R Users,
Is there a version of rpvm available for windows ? I have recently had
some problems with snow using SOCKS and was considering PVM as an
alternative.
Thanks in advance,

Convert Trixbox HVM to PVM
Hi list,
I recently installed the Trixbox distribution as an HVM and have now
converted it to a PVM. Found very few resources on Internet where
people had done this conversion so I had very little to compare with.
Wanted to ask for comments about the kernel used in the PVM after the
conversion.
Installing Trixbox and later installing the xenified kernel, gives a
kernel of 2.6.18-92.....

Requirements for a PVM enabled distro
(My apologies if this is the wrong list or if this question has been asked
before. I’ve done quite a bit of searching and can’t find an answer)
I am working on a heavily modified version of CentOS with a user-land that
mostly matches 5.4 and a kernel based on 6.2. I''ve found tutorials on how
to create a CentOS PVM (such as
