LANL Reveals 750-node RPi Cluster

This week, Los Alamos National Laboratory (LANL) has revealed its latest "High-performance computer" - a cluster of 750 Raspberry Pis. What is a Raspberry Pi? The Raspberry Pi is a low cost, credit-card sized computer that can do just about anything a typical desktop computer can do. They were developed by the Raspberry Pi Foundation, a United Kingdom charity, to help spread computing education especially in developing countries.
One problem the systems software community has is how to work on very large supercomputers without actually having to test on them, which can be very expensive and hard to access. This has led to the affordable solution of using thousands of inexpensive Raspberry Pi nodes for R&D work.
LANL’s Gary Grider, leader of the LANL High Performance Computing Division said, “The Raspberry Pi modules let developers figure out how to write this software and get it to work reliably without having a dedicated testbed of the same size, which would cost a quarter billion dollars and use 25 megawatts of electricity”. The Raspberry Pi pulls just two or three watts per node, making it cheap to run. In the future, Grider hopes to increase the system to thousands of nodes.
LANL's new 750-node Raspberry Pi cluster will be located at the LANL/New Mexico Consortium (NMC) Ultrascale Systems Research Center (USRC), in the NMC computer lab.  The NMC Ultrascale Systems Research Center(USRC) is a collaboration between the NMC and LANL to engage universities and industry nationally in exascale research. USRC is currently one of the largest programs at the NMC.
Many unsolved problems are standing in the way of achieving exascale computing. USRC was created to address these challenges through collaboration. USRC is interested in collaborations with University professors, students, and industry visitors.
