PRESS RELEASE
Today PEZY Computing is introducing a new MIPS64-based PEZY-SC2 family of many-core chips for supercomputers and HPC applications that will scale up to 4096 processing nodes. The 64-bit MIPS CPUs will act as the host processors for the system, making PEZY-SC2 the first generation of 64-bit HPC processors from the Japanese company.
PEZY is a fabless startup focusing on compute-intensive, highly parallel applications. The company already occupies the top three spots on the Green500 list of energy-efficient HPC makers, setting a world record with the Shoubo supercomputer that consumes only 7W per GFLOPS.
Founder and CEO Motoaki Saito named PEZY by combining the initials of four decimal unit prefixes: peta, exa, zeta and yotta. For reference, 1 petaFLOPS represents one thousand teraFLOPS (i.e. 1,000 trillion); exa, zetta and yotta are 1000 times the value of the former unit, respectively.

The MIPS architecture provides many great features for HPC applications, including hardware multithreading (up to four threads per CPU), 128-bit SIMD, and full hardware virtualization (up to 255 guest operating systems). For example, hardware multithreading is very important since many-core chips prefer to use in-order execution cores and rely on multithreading to avoid stalling.
MIPS has a rich history in HPC applications. Initially used in multiple SGI workstations and desktop computers in the late 1990s and early 2000s, 64-bit MIPS CPUs were later deployed inside several high-profile supercomputers, including the Cenju-4 parallel machine designed by NEC Corp or the SiCortex SC5832 supercomputer.
