ULP-HPC : Ultra Low-Power, High Performance Computing via Modeling and Optimization of Next Generation HPC Technologies

ULP-HPC project (leader: Satoshi Matsuoka) started in Oct. 2007, as a part of research field "Ultra Low Power Consumption Information Technology" of Japan Science and Technology Agency, Core Research of Evolutional Science and Technology.


Although the importance of high performance computing (HPC) is widely recognized, the power consumption of HPC systems are unacceptably high and increasing. We propose to develop an ultra low-power HPC (ULP-HPC) that will be 1000 times more power efficient than current systems in 10 years. Our aims are to (1) develop novel performance models and auto-tuning technologies based on mathematical theory; (2) utilize next generation HPC technologies such as many-core CPUs, vector accelerators, low-power memory, and low-power network hardware; and (3) develop power-efficient algorithms for actual large-scale HPC applications. The ULP-HPC will scale-down the supercomputer TSUBAME to desk side systems in 10 years, and we believe these systems will revolutionize scientific computing.
