ionz.org folding@home team!

folding@home

Since this past weekend I've decided to dedicated a piece of my resources to the folding@home project sponsored by standford.edu.  Folding@home is a massive cluster (made by you) dedicated  to computing protein folding.   The interesting thing about  the project they use the data we compute to study life threatening disease like cancer and Alzheimer's.  Hopefully some day these diseases can solved by our efforts to simulate them.  If anyone is interested in the project please stop by http://folding.stanford.edu/ and also check out the wiki at http://en.wikipedia.org/wiki/Folding@home

There's basically a client for every platform including:  Linux, Mac, & Windows
and even the PS3 on the cell architecture.

Btw our team id is:  52902

Need reiser4 on Gentoo?

Well After using Kororaa I learned that I have to depend on reiser4 and it’s still in development (even though the creator as a ill fate with the law)which sorta sucks in one respect since it’s bleeding edge. But I do enjoy the speed of reiser4 but I’ve ran into bugs like timestamp problems…~_~. But I think If you’ve gone this far and been one of those people who have tried kororaa and realized that you belong to Gentoo, I guess this is for you.

First off It’s a good idea to edit your /etc/make.conf using your favorite editor (I still love nano/pico) and this line (If you haven’t done so)

  • PORTDIR_OVERLAY=/usr/local/portage

Now to make your Reiser4 gentoo Kernel directory; Create this folder using mkdir

  • mkdir -p /usr/local/portage/sys-kernel/reiser4-gentoo-sources/

Time to get the ebuild….(wget :S)

  • wget http://dev.ionz.org/kernel/reiser4-gentoo-sources-2.6.17-r7.ebuild

Digest it!!!

  • ebuild /usr/local/portage/sys-kernel/reiser4-gentoo-sources/reiser4-gentoo-sources-2.6.17-r7.ebuild digest

Afterward add your reiser4 enabled kernel gentoo to your use and keywords

  • echo “sys-kernel/reiser4-gentoo-sources symlink” >> /etc/portage/package.use
  • echo “sys-kernel/reiser4-gentoo-sources” >> /etc/portage/package.keywords

And Finally….

  • emerge reiser4-gentoo-sources

Then you know the drill…well you should (If not leave a comment or send a e-mail to me)

Just one thing though make sure you have Y under Cryptographic Options for reiser4 and enable “Prompt for development and/or incomplete code/drivers” in the “Code maturity level” options

Getting AIGLX+Beryl to Work on Gentoo

First off you need Xorg 7.1 so need to update your xorg if haven’t done so.

So these lines to add to /etc/portage/package.keywords

#Modular X 7.1
Then it's a good idea to update your portage by emerge --sync
afterwards just use emerge --update xorg-x11 xorg-server xf86-input-evdev xf86-input-mouse xf86-input-keyboard xf86-video-vga xf86-video-vesa
to update xorg.  You might want to try adding aiglx to your use flags in /etc/make.conf
Afterwards edit your /etc/X11/xorg.conf and add these lines
Section "DRI"
Group 0
Mode 0666
EndSection

Section "ServerLayout"
Option         "AIGLX" "true"
EndSection

Section "Extensions"
Option         "Composite"   "Enable"
EndSection

Section "Device"
Option      "XAANoOffscreenPixmaps" "true"
Option      "DRI"     "true"
EndSection
And that ends the aiglx part off this tutorial
Read on for Beryl
