“…For example, according to SIA (Semiconductor Industry Association) projections for the year 2005 [13], f c will be 375 MHz (i.e., frequency for inter-chip data transfers), and therefore lasers operating at 32 × 375 MHz = 12 GHz will then be needed. Such lasers and corresponding multiplexers/demultiplexers already exist [19,20]. A typical clear plastic has a transmission factor of 0.25 dB/cm.…”

An innovative design is proposed for an MIMD distributed shared-memory (DSM) parallel computer capable of achieving gracious performance with technology expected to become feasible/viable in less than a decade. This New Millennium Computing Point Design was chosen by NSF, DARPA, and NASA as having the potential to deliver 100 TeraFLOPS and 1 PetaFLOPS performance by the year 2005 and 2007, respectively. Its scalability guarantees a lifetime extending well into the next century. Our design takes advantage of free-space optical technologies, with simple guided-wave concepts, to produce a 1D building block (BB) that implements efficiently a large, fully connected system of processors. Designing fully connected, large systems of electronic processors could be a very beneficial impact of optics on massively parallel processing. A 2D structure is proposed for the complete system, where the aforementioned 1D BB is extended into two dimensions. This architecture behaves like a 2D generalized hypercube, which is characterized by outstanding performance and extremely high wiring complexity that prohibits its electronics-only implementation. With readily available technology, a mesh of clear plastic/glass bars in our design facilitate point-to-point bit-parallel transmissions that utilize wavelength-division multiplexing (WDM) and follow dedicated optical paths. Each processor is mounted on a card. Each card contains eight processors interconnected locally via an electronic crossbar. Taking advantage of higher-speed optical technologies, all eight processors share the same communications interface to the optical medium using time-division multiplexing (TDM). A case study for 100 TeraFLOPS performance by the year 2005 is investigated in detail; the characteristics of chosen hardware components in the case study conform to SIA (Semiconductor Industry Association) projections. An impressive property of our system is that its bisection bandwidth matches, within an order of magnitude, the performance of its computation engine. Performance results based on the implementation of various important algorithmic kernels show that our design could have a tremendous, positive impact on massively parallel computing. 2D and 3D implementations of our design could achieve gracious (i.e., sustained) PetaFLOPS performance before the end of the next decade.
