Default Knight's Corner PCIe 7120A Coprocessor

This thread is intended as a reference thread for Mersenne exponents of special forms. For discussion, please use the reference discussion thread https://www.mersenneforum.org/showthread.php?t=23383. (Discussion posts added to this thread may be moved or deleted without notice or recourse.)


The 7120A is an actively cooled Knights Corner dual slot PCIe add-in coprocessor, with 16GB of on-card ram, a special embedded os uOS, and a blower for cooling. Its performance is likely a fraction of a modern gpu. It communicates with the host system over the PCIe bus as if it was a separate networked system. Intel's spec sheet is here. Briefly: 61 cores, 1.238 Ghz base clock, 1.33 turbo clock, 30.5 MB L2 Cache, 16GB ram, 352 GB/s ram bandwidth, 300 W TDP, PCIe 2.0, Intel IMCI instruction set.
