Hello to all, I''ve lucked onto a case of Opteron 850''s and hope to try some 4 way and 8 way systems with Xen. Can someone recommend a good 8x or even 4x socket 940 board that will be condusive to a good experience with Xen? This will be only for Paravirtualized guests (3.0.4). My hope is to play more with Xen''s credit scheduler and try some of the arch mixing

I''ve been brainstorming... I want to create a 2-node HA active/active cluster (In other words I want to run a handful of DomUs on one node and a handful on another). In the event of a failure I want all DomUs to fail over to the other node and start working immediately. I want absolutely no single-points-of-failure. I want to do it with free software and no special hardware. I want

Dear R developers, I have a new class, which I called "Molecule", and have tried to define = a "+" operation for 2 objects of this class. This is what I have written so far, although the method is not complete = (I'm trying to look at it at intermediate stages): setMethod( f=3D"+", signature(x=3D"Molecule",y=3D"Molecule"),

Dear all, I have a very small script to plot a function. Here it is: ########################################## sinca <- function(N,th) { return(sin((N+0.5)*th)/sin(0.5*th)) } plot_sinca <- function(N) { x <- seq(-5*pi,5*pi,by=pi/100) y <- rep(0,length=length(x)) for (i in 1:length(x))y[i] <- sinca(N,x[i]) plot(x,y,type="l",ylim=c(0,2*N+4)) return(c(x,y)) }

Dear R community, I would be greatful if somebody could shed light on the following. I have created a set of 6 points to check how centroid agglomeration works in cluster analysis: > Y <- data.frame(x=c(-1,1,1,-1,10,12),y=c(1,1,-1,-1,0,0)) It is quite intuitive to understand that the last clusters to be joined will be {1,2,3,4} with {5,6}. Now, the centroid for the first cluster has

Dear R gurus and users, I seem to have problem finding the right tool for plotting convex hulls over 2D plots, after a cluster analysis. In fact I would like to draw a convex hull in 2D for a generic group of points. I found a "convhulln", but this doesn't seem to give me a convex hull. Here is what I do: > library(mvtnorm) > Mean <- c(2,1) > Sigma <-

Dear RGL experts, I haven't been able to add greek letters to my rgl plot3d. I have tried "expression" with no success. Here is the interested bit: > library(rgl) > cb <- cube3d() > plot3d(cb,xlab=expression(alpha),ylab="",zlab="",box=FALSE,alpha=0.5) The expression(alpha) appears as "alpha", rather than as a greek symbol. I suspect greek

Hello All, I wanted to perform a fourier transform on high frequency financial data. I have searched and have not found much on this topic for R. I was wondering if anyone has used any libraries for it or have come across any papers I may read. Many Thanks, Neil Gupta [[alternative HTML version deleted]]

Dear R community (and Duncan more specifically), I can't work out how to make additional light sources work in rgl. Here is the example. First I create a cube and visualize it: > cubo <- cube3d(col="black") > shade3d(cubo) Next I position the viewpoint at theta=0 and phi=30: > view3d(theta=0,phi=30) Next, I want to create a 2nd light source which diffuses red light

Dear R community, I would like to source a file in my linux system to set a few environment variables. I have tried: > system("source /home/james/build//ccp4-6.1.13/include/ccp4.setup") and got: sh: source: not found In fact, using Sys.which("source") I get an empty string. How can I source that ccp4.setup file from within an R session? J Dr James Foadi PhD Membrane

Dear R community, I'm trying to develop a fast way of summing specific rows of a large data frame. Here is an example of the kind of data frames I'm dealing with: > refls H K L M/ISYM BATCH I SIGI 43247 1 0 5 21 79 61.44117 2.20553 1040 1 0 5 257 6 15.16316 0.54431 2324 1 0 5 257 5 46.76152 1.67858 31515 1 0 5 259 60 57.97305

Hi, Has anyone tried to install Vista B2 on VT machine? Dose Xen 3.0.2 support Vista? Thanks! _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Noniko, I saw your posting titled "SUSE10.1 has a nice Xen package again" and I was wondering if you had found any documentation on how to run Fedora Core 5 on top of SUSE10.1. Did you build the Fedora environment on a separate Fedora machine and then brought it over to the SUSE machine or did you find the Fedora tools (Yum/Anaconda) on SUSE? Many thanks in advance.

Hello, I am a newbie of Xen and just started with SUSE9.3-packaged Xen. The packaged document README.SuSE and script mk-xen-resucue-img.sh did me a great help, I could run sample ttylinux-xen and rescue-based Suse with xen. Now I''m trying YaST dirinstall. I Created a root FS image and installed a "minimal system required" using YaST . This domain booted and login console

I have a plot where the values of the y axis go from a positive number to a negative number and I want the x axis to intercept at zero rather than at the bottom of the y axis, regardless of its value. Can anyone help me to do this? Thanks in advance Vivien Vivien Kent MSc Oxon PhD candidate Evolutionary Anthropology Research Group Department of Anthropology Durham University Dawson

Hello, I'm posting this to the list in case others run into the same issue. I've recently been connecting * to a legacy Avaya InDEX switch over E1 ISDN PRI here in the UK. Everything was working OK, except that DTMF digits were not being recognised by * when sent by the Avaya switch to the * system. Instead, the background noise of the call centre would be silenced while

Hi, Tom I recently got SUSE-Xen running. During the trial I got similar error: "kernel panic - not syncing: VFS: Unable tomount root fs on unknown-block (3, 1)" This was fixed when I add to xen-config file this line: # Optional ramdisk. ramdisk = "/boot/initrd-xen" It might be commented out if you use the config file example "xmexample1".

Sorry, I made a mistake to re-install my SUSE without backing-up the original entry of this topic in my mailbox.But please don''t mind, that previous mailbox itself had been very new and contained only a few mail data. Anyway I''m sorry I had to start a new thread. Hi, Okamoto-san, Thank you very much! I could log in SUSE runnning in unprivileged domain by your advice. >You
