The Mathematics Extreme Computation Cluster At Harvard is a cluster of 6 dual Athlon processor computers, funded in large part by William R. Hearst III, and administered by William Stein.
There is a COMPUTATION LOG, which describes a little of what we're doing using MECCAH.
I wrote an article about my experiences building
and administering MECCAH.
Technical Specifications: MECCAH consists of 6 dual-processor AMD Athlon MP2800 nodes. The master node has 3GB of RAM (and at present only Athlon MP2000 processors), and the remaining 5 nodes have 2GB RAM each. The nodes run Red Hat Linux 9.0 and are networked with 100Mbs ethernet.
Design: (updated May 2005) Alex Healy, Wayne Whitney,
and William Stein designed the cluster in Spring
2002 for use by the Department of
Mathematics at Harvard University. The nodes
in the cluster were purchased custom made from
pcsforeveryone,
a local computer chop shop. They were flexible
and helpful with the initial configuration of
the machine. I had some
initial trouble with warranty-work from pcsforeveryone
back in 2002, but in April when the power
supplies failed on node 5, pcsforeveryone
offered to upgrade the node completely for free
to a dual-Opteron box. They sent a courier to
the math department, picked up the machine,
replaced the motherboard, power supply, and CPU
with a dual-Opteron based system, and the new
node works well. That's great service!
