A single ZettaScaler immersion tank can house 16 bricks, which works out to 512 PEZY-SC2 processors. That means each tank can bring in 1,048,576 cores and 8,388,608 threads. That's an incredibly mind-bending number, sure, but perhaps the size of the relatively small immersion tank is the most impressive. That's performance density at its finest.
The Gyoukou supercomputer employs 10,000 PEZY-SC2 chips spread over 20 immersion tanks, but the company "only" enabled 1,984 cores per chip, which equates to 19,840,000 cores. Each core wields eight threads, which works out to more than 158 million threads. That system also includes 1,250 sixteen-core Xeon-D processors, adding over 20,000 Intel cores. In aggregate, that's the most cores ever packed into a single supercomputer.
The Gyoukou system is ranked fifth on the Green500 list for power efficiency and fourth on the Top500 list for performance. It delivers up to 19,135 TFLOPS and 14.173 GFLOPS-per-watt.
Incredible numbers aside, the company also has its PEZY-SC3 chips in development, with 8,192 cores and 65,536 threads per chip. That means the core and thread counts of its next-generation ZettaScaler systems will be, well, beyond astounding. We can't wait.
