The SDSC Sandbox is a space at the San Diego Supercomputer Center for UCSD undergraduates to develop learning materials for middle and high school students to learn parallel computing. Right now, we're focusing on the Raspberry Pi as the ideal tool for presenting a simplified model of a supercomputer. Trust us, it's a lot easier to build a cluster out of computers that weigh less than 1% of a typical server--and the network team is more than willing to part with 100BASE-TX switches.
