US energy has a relatively low cost of about $1/watt-year. Non-US energy costs are generally higher. For many energy efficiency is not a significant individual cost. Yet, consider the following...
CASE 1. Embedded High Performance Computing.
Sustainable PERFORMANCE/WATT can be a strong processor selection criteria for *embedded* processor selection including embedded high performance computing. Hence, vendors in the niche embedded high performance market tend to use PowerPC and DSP chips, not Alpha, Pentium or SPARC for dense compute solutions.
"Several problems were caused by the power consumption and the heat in that small laboratory. The Paderborn people needed the fire brigade to pump cold air into the room. The power consumption was about 10 - 12 KWatt. Switching on only the power supplies of the nodes, the electric fuses switched off."
SIXTEEN A/C Units plus FOUR 750-ton chillers plus TWO 10MW power stations (major UPS feature)
CASE 4. Aggregate World Energy Consumption (Green perspective)
Now consider 100,000,000 processors on desktops (far less than one per world capita)
100,000,000 * 30 watts-year * US$1/watt-year = US$3 Billion each year (without consideration for cooling costs, higher average world energy prices, CPU fan MTBF costs & such)
Hey, what's US$30 / year per CPU for a typical US home wallet??? Well maybe not much to many reading this... however, the energy costs can add up. Embedded system designers, large scale system installations, and environmentally sensitive people know what I'm talking about.

Hmmm... http://www.musicdns.org/ "Open Source, Open Data for Digital Music" powered by MusicIP.
We have been working on a ground breaking music discovery technology called MusicMagic... which does what captainclever is asking.
You can read more about MusicMagic in "Moving Linux into Commercial Applications" which discusses the use of Linux for MusicMagic.

Vendor examples: CSPI, Mercury, Sky
Did folks notice that Black Lab Linux (see optional software) is working with MPI Software Technologies? Look close, MPI Software Technologies is actively supporting *embedded* MPI & MPI-RT.
CASE 2. Not Too Large Clusters (50 or so processors)
Also, notice the HPC Wire news article posted on the Top 500 site where...
