Important points about Blue Gene/L

z Embedded technology promises to be an efficient path toward building massively parallel computers optimized at the system level

z Cost / performance is ~ 20 to 50 times better than standard methods to get to teraflops

z Low Power is critical to achieving a dense, simple, inexpensive packaging solution

z Blue Gene/L will have a scientific reach far beyond existing limits for a large class of important scientific problems

z Blue Gene/L will give insight into possible future product directions

z Blue Gene/L hardware will be flexible

z A mature, sophisticated software environment needs to be developed to really determine the reach (both scientific and commercial) of this architecture
