The wiki is being retired!

Documentation is now handled by the same processes we use for code: Add something to the Documentation/ directory in the coreboot repo, and it will be rendered to Contributions welcome!

The first LinuxBIOS cluster, see SC 2000.
Ed, a 128 node Alpha cluster running LinuxBIOS.

This page exists for historical reasons since these are the first systems that ever ran LinuxBIOS (what became coreboot).

4/22/2002: The lunchbox gets a makeover!

Bento, aka the lunchbox cluster, is our newest LinuxBIOS/BProc cluster. Okay, so it's really in a toolbox, so think of it as a lunchbox for the really hungry. Thanks to Rob Armstrong and Mitch Williams of the Embedded Reasoning Institute at Sandia - Livermore for turning us on to this hardware. They're way ahead of us in terms of picking out good, small iron since they're sending their's up in the nose cone of a missle.

Front-end: IBM Thinkpad T23 (Ron's laptop) running BProc from the Clustermatic W2002 release

7 smartCoreP5 nodes from Digital Logic running LinuxBIOS configured with BProc support

1 (one) naked 3Com 100 Mb HUB (removed from it's case)

3 IBM Thinkpad 12 V power bricks

1 (one) Master Mechanic yellow plastic toolbox

This is a nice little demo unit to take around the country. It's been through a lot already -- Ron's was randomly selected to have his all his bag searched ("uh, what's that?" said security), and now he's blacklisted forever. But more importantly, it's been great way for us to get real, kernel-level development work done while traveling. For example, in Houston Matt was able to work on Supermon when (not) in meetings. Ron integrated Lm_sensors into Supermon in California. You just can't do that unless you have a cluster that can be easily rebooted (i.e., on-site).


The rebuilt lunchbox

The lunchbox cluster recently underwent a change. The change was motivated by the need to improve the use of mounting hardware, replace the hub with a switch, and cooling issues in the case. We've renamed it "DQ" -- we'll let you guess what that means.

Here's the parts list:

Front-end: Ron's IBM Thinkpad T23 or Erik's IBM Thinkpad X20 or Sung' Sony VAIO Z505JS.

6 smartCoreP5 nodes from Digital Logic running LinuxBIOS configured with BProc support (one less than the lunchbox due to the spacers required to make better use of the mounting hardware)

1 (one) NetGear 100 Mb switch (with its own power brick)

2 IBM Thinkpad 12 V power bricks

1 (one) CD storage case

1 pink fuzzy strap
