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.

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:

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

Authenticating AD users and Local users
Thank you for replying!
I can login with my Active Directory credentials, but I can’t login using the local CentOS “svc_dictations” account.
I created the local account usingusing “adduser”, “smbpasswd”, and then updating my smb.conf file (below).
Thank you,

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.

FPC / FPE fix
Mr Sidebotham
I wanted to thank you for posting your fix of the camera recognition
problem for FPC. I just updated to Tiger (I usually wait 6 months
after new introductions) and was shocked at the discovery of the
non-recognition and crash. I am currently working your fix. Even if
it dose not work for me, I want to thank you for posting such a
useful message.

accented characters in isolinux
hey people
I'm new to the list and would like to say thanks to everyone that has
worked on syslinux/isolinux. It's one of those tools that everyone uses
at some stage but no-one ever really takes much notice of it - mainly
because *it just works*. So congrats ...
Now onto my question - I am customizing Fedora Core and I want to change

kernel update with yum - no grub entry
Hi people
I am new to this list - actually I am one of (probably) a few who are
jumping ship from WBEL. I feel like a bit of a scab jumping over at this
time - but we all make mistakes eh?
I have installed CentOS and ran 'yum update' and installed everything it
prompted me for. After a reboot, I realised I had booted into the same
original kernel-2.4.21-20.EL.c0smp and not the updated

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

snow package on multi core unix box
Is the rmpi package (or rpvm) needed to exploit multiple cores on a
single unix box using the snow package. The documentation of the package
does not provide info about setting up a single machine with multiple
cores. Also, if how effective is it to run a bayesian simulation on
parallel (or distributed) processors using the snow package.
Thanks,

Looking for suggestions on how to debug pvm/snow proc's
Hi All -
I'm running a faily long script that uses rpvm & snowFT to spawn off
multiple processes with the 'clusterApplyFT' function.
Specifically, what happens is that the head node generates a number of seed
clusters that are then spawned off to the pvm cluster (in this case, nodes
on a 4 dual-core machine) using clusterApplyFT to apply a function to each
seed cluster that

How to increase the printing speed
Hi Brian,
Thank you very much. Now I am able to the printer on Win95 box.
But I don't know why the printing is very slow. Infact the printer waits
for a while before taking the next page. Is there a way to increase the
printing speed. Another important thing is that I cannot use any printer
option in the printer panel on IRIX box. It says "printer type

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

A question regarding random effects in 'aov' function
Hi,
I am doing an analysis to see if these is tissue specific effects on the
gene expression data .
Our data were collected from 6 different labs (batch effects). lab 1 has
tissue type 1 and tissue type 2, lab 2 has tissue 3, 4,5,6. The other labs
has one tissue type each. The 'sample' data is as below:

problem fitting linear mixed models
Hello,
I'm fitting linear mixed models to gene-expression data from
microarrays, in a data set where 4608 genes are studied.
For a sample of 5 subjects and for each gene we observe the expression
level (Intensity) in four different tissues: N, Tp, Tx and M.
I want to test whether the expression level is different accross
tissues. Between-subject variability is modeled with a random
