Welcome to The Limulus Project ™

Project Status

October 22, 2008: I have posted the new  results and the issue with Jumbo frames was due to flow control in the NICs. I used ethtool to turn off flow control and was able to see the expected performance boost for larger frames, the variability seemed to get worse however. I'll be writing this up and posting it on  ClusterMonkey real soon. Also,  Open MX 1.0.0 has been released.

August 13, 2008: I recently  posted some interesting benchmarks for Norbert. I have been testing  Open-MX over GigE and found some lower throughput when Jumbo frames are used. I think it could be the low cost switches. More testing later this week. I just noticed that the latest version of OpenMX (0.9.1) can run over standard frame sizes (1500). More testing indeed.

July 31, 2008: At long last an update! I have been busy with the software. Our goal is to have a Fedora 8 spin ready by the end of August 2008. We will also be adding our complete set of spec files plus our build/install scripts to the source tree. We will also host {S}RPMS at this time. Staring in September we will be working on packaging issues (i.e a case). In the mean time you can get more background from a pre-print (draft actually) of my  Limulus Article (pdf) in the November 2007 Issue of  Linux Magazine (It has not made it to the Linux Magazine website yet).

January 1, 2008: The Trac page is up and running. The next step is to get the Wiki and Milestones completed. There is now a hardware manifest and pictures for the The Norbert Limulus Cluster.

What is the Limulus Project?

The Limulus project goal is to create and maintain an open specification and software stack for a personal cluster. Ideally, a user should be able to build a small personal cluster using the Limulus reference design and low cost hardware. In addition, a freely available turn-key Linux based software stack will be created and maintained for use on the Limulus design.
