Xeon Phi was a unique processor built by the Intel Corporation. A successor to Intel's failed Larrabee project, the first generation of Xeon Phi was a PCIe card with up to 61 K1om CPU cores. Although not code comptabile with x86, the CPU cores were comparable to that of a low end Atom processor, and the sheer number of cores provided performance advantages to certain workloads, and the cards soon found their way into many of the world's largest supercomputers at the time, including the Tianhe-2 supercompute, which at the time of it's release was the #1 Supercomputer on the Top500 list. Xeon Phi would eventually be cancelled after the 2.5th gen, codenamed Knight's Mill, when issues with Intel's 10nm node led to a delay in the development of the third generation Xeon Phi processors.
This group aims to breathe new life into Xeon Phis by making useful software functional on the cards, as well as discovering more about the cards and their history. Although they were discontinued, Xeon Phi still represents an incredibly important part of computer history, and the socketed Knights Landing processors paved the way for manycore processors and their respective workloads such as the modern EPYC Genoa and Bergamo CPUs.
