The OptIPuter Project—Eliminating Bandwidth as a Barrier to Collaboration and Analysis DARPA Microsystems Technology Office Arlington, VA December 13, 2002 Dr. Larry Smarr Director, California Institute for Telecommunications and Information Technologies Harry E.

Abstract The OptIPuter is a radical distributed visualization, teleimmersion, data mining, and computing architecture. The National Science Foundation recently awarded a six-campus research consortium a five-year large Information Technology Research grant to construct working prototypes of the OptIPuter on campus, regional, national, and international scales. The OptIPuter project is driven by applications leadership from two scientific communities, the US National NSF's EarthScope and the National Institutes of Health's Biomedical Imaging Research Network (BIRN), both of which are beginning to produce a flood of large 3D data objects (e.g., 3D brain images or a SAR terrain datasets) which are stored in distributed federated data repositories. Essentially, the OptIPuter is a "virtual metacomputer" in which the individual "processors" are widely distributed Linux PC clusters; the "backplane" is provided by Internet Protocol (IP) delivered over multiple dedicated 1-10 Gbps optical wavelengths; and, the "mass storage systems" are large distributed scientific data repositories, fed by scientific instruments as OptIPuter peripheral devices, operated in near real-time. Collaboration, visualization, and teleimmersion tools are provided on tiled mono or stereo super-high definition screens directly connected to the OptIPuter to enable distributed analysis and decision making. The OptIPuter project aims at the re-optimization of the entire Grid stack of software abstractions, learning how, as George Gilder suggests, to "waste" bandwidth and storage in order to conserve increasingly "scarce" high-end computing and people time in this new world of inverted values.

The OptIPuter Philosophy Bandwidth is getting cheaper faster than storage.Storage is getting cheaper faster than computing. Exponentials are crossing. “A global economy designed to waste transistors, power, and silicon area -and conserve bandwidth above all- is breaking apart and reorganizing itself to waste bandwidth and conserve power, silicon area, and transistors." George Gilder Telecosm (2000)

OptIPuter is Exploring Quanta as a High Performance Middleware • Quanta is a high performance networking toolkit / API. • Reliable Blast UDP: • Assumes you are running over an over-provisioned or dedicated network. • Excellent for photonic networks, don’t try this on commodity Internet. • It is FAST! • It is very predictable. • We give you a prediction equation to predict performance. This is useful for the application. • It is most suited for transfering very large payloads. • At higher data rates processor is 100% loaded so dual processors are needed for your application to move data and do useful work at the same time.

TeraVision Over WAN : Greece to Chicago Throughput TCP Performance Over WAN Is Poor; Windows Performance Is Lower Than Linux; Synchronization Reduces Frame Rate.
Reliable Blast UDP (RBUDP) • At IGrid 2002 all applications which were able to make the most effective use of the 10G link from Chicago to Amsterdam used UDP • RBUDP[1], SABUL[2] and Tsunami[3] are all similar protocols that use UDP for bulk data transfer- all of which are based on NETBLT- RFC969 • RBUDP has fewer memory copies & a prediction function to let applications know what kind of performance to expect. • [1] J.
