Just setup everything within a VM environment on one of my quad core boxes and it is running smoothly. Anyone else run projects on virtual machines (vm)?

I ran Cosmo for a while on my Apple Mac Pro using VMWare. It worked out nicely. I was running 2 dual core virtual machines which keep all 4 cores @ 100%. The overhead used by VMWare was surprising low.
2) Message boards : Number crunching : Linux 32 or 64 bit? (Message 5437)

If you are a Linux beginner (I am), I recommend you start with Ubuntu 64 bit. I tried a number of distros before I found Ubuntu and shazam! It does me just fine.

It helps if you have a spare 64 bit box so you can try a number of distros to find one that fits your personal style. I use an older socket 754 box with a small hard drive. If one distro gives you fits, blow it away and burn another.

I am currently playing with Tiny Me on a nostalgia build. It's a 1.4ghz tualatin Pentium III with 512 meg of ecc ram. This is not a cruncher by any means, but lets me play with 32 bit distros to my heart's content.

The Synaptic package manager in Ubuntu allows you to select and install additional software like Boinc with no hassles.

The one "catch" with Ubuntu is the power saving feature, which is set to power saving mode by default. To get much thoughput out of Boinc, you need to change the setting to "Performance".

I saw several notices that the source code was available, but no link to it anyplace obvious. How do we get a copy of the source?

which one is better for milkyway?

64 bit, with a low overhead distro like Slamd64 or Bluewhite. You can build your own with Linux From Scratch or compile what you want with Gentoo.

[edit:] Try a live CD and install nothing, start BOINC manualy. [/edit]

Arch Linux is very, very good if you have some Linux experience and like to live on the "bleeding edge" (the only down-side is Arch X86_64 does not support running 32 bit apps). Also, almost any distro can be made to run OK, you just need to take the time to turn off a bunch of un-needed services (I'm running CentOS on most of my machines and 3/4 of the services it installs need to be turned off). PS- The reason for CentOS is it supports clustering, I'm toying with turning my AMD machines into one 20 core machine.
