'It's not easy trying to build scalable systems from commodity hardware designed for assembling desktop computers and small servers.' Per the article, 'As the number of CPUs in a Beowulf-style cluster-a group of PCs linked via Ethernet-increases and memory is distributed instead of shared, the efficiency of each processor drops as more are added,' but 'Unlimited's solution involves tailoring Linux running on each node in a cluster, rather than treating all the nodes as peers.'"
Looks like Cray engineers think about clustering
even when they're not at Cray.
