The Neumann Syndrome calls for a revolution

| Abstract | Computing the von Neumann style is tremendously inefficient because of the von Neumann Syndrome. Multiple layers of massive overhead phenomena at run time often lead to code sizes of astronomic dimensions. And most of these masses of code have to be resident at drastically slower off-chip memory. The many-core programming crisis, which stems from the von Neumann syndrome, requires complete re-mapping and re-implementation of applications. A sufficiently large population of programmers qualified to program applications for four and more cores is far from being available. Another problem is a high-priority political issue: the very high energy consumption of von-Neumann-based systems. The electricity consumption of all visible and hidden computers reaches more than 20 percent of our total electricity consumption. A study predicts this will rise to 35 percent to 50 percent for the United States by the year 2020. Fundamental concepts from reconfigurable computing promise a speed-up of almost one order of magnitude (for some application areas up to two or three orders of magnitude) while at the same time slashing the electricity bill down to 10 percent or less. It is really time to fully exploit the most disruptive revolution since the mainframe---reconfigurable computing---and to cope with the many-core crisis and to reverse the down trend in enrollment. Contracts between microprocessor firms and reconfigurable computing system vendors are on the way but not yet published. Reconfigurable computing shows us the road map to the personal desktop supercomputer, making HPC affordable for small firms and for individuals, and to a drastic reduction of energy consumption. The technology is ready, but users are not. The talk sketches a roadmap requiring a redefinition of the entire discipline, inspired by the mindset of reconfigurable computing. |
