Vicor Components Power the World’s First Super Computer with a Performance Density of 1.5 PetaFLOPS/m3

November 17, 2016

SC 16 logoAt SC16 yesterday, ExaScaler and PEZY Computing unveiled the ZettaScaler-1.8, the first Super Computer to achieve a performance density of 1.5 PetaFLOPS/m3 (Rpeak). This unprecedented achievement was enabled by ExaScaler immersion liquid cooling technology and Vicor’s power components, that enable direct conversion of 380 V to 48 V (380 V High Voltage DC (HVDC)) and 48 V to 1 V (48 V direct CPU)

The ZettaScaler 1.8 achieved its impressive 1.5 PetaFLOPS/m3 performance density with an incredible 20% improvement in efficiency, through a combination of higher voltage distribution and reduced voltage conversion steps enabled by Vicor’s high efficiency and high density power modules.

By using 380 V DC for the main power distribution, I2R losses in the cabling are significantly reduced and by using Vicor’s converters with 98% peak efficiency and 2750 W/in3 power density, further substantial system efficiency and density gains were achieved in converting to 48 V.

Further efficiency and density gains are made possible by distributing the 48 V to Vicor’s high density, high efficiency direct-to-PoL current multipliers, feeding PEZY Computing’s low voltage, high current processors. Other auxiliary voltage rails on the processor board are supplied by CoolPower ZVS buck regulators which also directly convert the 48 V to additional loads

Incredibly, PEZY Computing has even more ambitious goals for next year. The ZettaScaler-1.8 is an advanced prototype of the ZettaScaler-2.0, which is due to be released in 2017 with a performance density three times higher than the ZettaScaler-1.8.
