What was the NetWinder cluster that Corel showed?
At the Atlanta Linux Showcase, Corel showed a cluster of NetWinders that have been removed from their cases and mounted in a stack. The “master” NetWinder has a hard disk and can control the power supplies of the “slaves.” The slaves are set up to boot (using NeTTrom’s DHCP) from the master and run using an NFS filesystem. All of the systems communicate over one Ethernet bus (and the master masquerades the system to the outside world). You can see a snapshot at http://www.netwinder.org/~ralphs/images/bigbeowulf.jpg (there are also some other NetWinder snapshots in that directory).
