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,, which would have placed it at #393 on the
TOP500 List at the time.
Since 2002, the SSS project has evolved in two different directions:
(1) a low-power, architectural approach and (2) a power-aware,
software-based approach. Early on, the architectural approach was
adopted by a start-up company in Silicon Valley and transformed into
a low-power, cluster workstation.
In the meantime, our software-based approach leveraged 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. The software-based approach is based on
our innovative β algorithm, which has been commercialized as
EnergyFit.
