What is the Pleiades?
The Pleiades, one of the world's most powerful supercomputers, represents NASA's state-of-the-art technology for meeting the agency's supercomputing requirements, enabling NASA scientists and engineers to conduct modeling and simulation for NASA projects. This distributed-memory SGI/HPE ICE cluster is connected with InfiniBand in a dual-plane hypercube technology.
The system contains the following types of Intel Xeon processors: E5-2680v4 (Broadwell), E5-2680v3 (Haswell), E5-2680v2 (Ivy Bridge), and E5-2670 (Sandy Bridge). The Pleiades is named after the astronomical open star cluster of the same name.
