For each step there is: • an “Efficiency” number that indicates what fraction of the power delivered at the step’s input is passed to the output, • a “Delivered” number that indicated how must of the power (in watts) is passed on to the output if the power on the line above is presented as input, • and a “Dissipated” power (again in watts) that is lost by the process. 52 watts are dissipated as heat in the power conversion process. 4 watts are dissipated as heat in the power conversion process.

Explicit management of the memory hierarchy, however, places additional burdens on 30 the application programmer and compiler writer. Processing-In-Memory (PIM) chips reduce the latency of a memory access, and increase the effective bandwidth by using more of the bits that are read from a dense, usually DRAM, memory array at each access by placing one or more processors on the chip with the memory. A variety of different processor architectures and interconnect patterns have been used, ranging from arrangements of more or less conventional cores on EXECUBE[85], Cyclops[8] and Intel’s Teraflops Research Chip[149], “memory chips” with embedded processing such as DIVA[60] and YUKON[83], and VIRAM[88] - where multiple vector units are integrated onto a DRAM.

S. Defense Science Board and UK Defence Scientific Advisory Council Task Force on Defense Critical Technologies[18] was charged with examine five transformational technology areas that are critical to the defense needs of the US and UK, including Advanced Command Environments, Persistent Surveillance, Power sources for small distributed sensor networks, High Performance Computing, and Defence Critical Electronic Components. They key finding on the HPC side were that there are a number of applications that cannot be solved with sufficient speed or precision today, that the high performance needs of national security will not be satisfied by systems designed for broader commercial market, and that two new memory-intensive applications are becoming especially important: knowledge discovery and integration and image and video processing.
