Welcome to the home of the Supercomputing in Small Spaces
(SSS) project. Wu Feng,
along with Michael S. Warren
and Eric H. Weigle,
started this project back in September 2001 with a 24-node Bladed
Beowulf cluster dubbed MetaBlade, which consumed only 400 watts of
power and occupied five square feet of space. By April 2002, the
SSS project unveiled its 240-node "Green Destiny" cluster, which
consumed as little as 3.2 kilowatts (i.e., two hairdryers) while
still occupying only five square feet of space and delivering over
100 Gflops on the LINPACK
benchmark.
Since 2002, the SSS project has evolved in two different directions:
architecture- and software-based. The architectural approach has
been adopted by a start-up company in Silicon Valley and transformed into a low-power, cluster workstation.
In the meantime, our software-based approach leverages dynamic
frequency and voltage scaling (DVFS) on commodity high-performance
computing (HPC) microprocessors, such as the AMD Opteron, to reduce
CPU power consumption by as much as 70% with nearly negligible
impact on performance.
