Method and apparatus for performing memory prefetching

Title: Method and apparatus for performing memory prefetching

Abstract

A method and apparatus for performing memory prefetching includes determining whether to initiate prefetching. Upon a determination to initiate prefetching, a first memory row is determined as a suitable prefetch candidate, and it is determined whether a particular set of one or more cachelines of the first memory row is to be prefetched.

Method and apparatus of parallel computing with simultaneously operating stream prefetching and list prefetching engines

Patent Boyle, Peter A.; Christ, Norman H.; Gara, Alan; ...

A prefetch system improves a performance of a parallel computing system. The parallel computing system includes a plurality of computing nodes. A computing node includes at least one processor and at least one memory device. The prefetch system includes at least one stream prefetch engine and at least one list prefetch engine. The prefetch system operates those engines simultaneously. After the at least one processor issues a command, the prefetch system passes the command to a stream prefetch engine and a list prefetch engine. The prefetch system operates the stream prefetch engine and the list prefetch engine to prefetch datamore »« less

Method and apparatus of prefetching streams of varying prefetch depth

Patent Gara, Alan [Mount Kisco, NY]; Ohmacht, Martin [Yorktown Heights, NY]; Salapura, Valentina [Chappaqua, NY]; ...

Method and apparatus of prefetching streams of varying prefetch depth dynamically changes the depth of prefetching so that the number of multiple streams as well as the hit rate of a single stream are optimized. The method and apparatus in one aspect monitor a plurality of load requests from a processing unit for data in a prefetch buffer, determine an access pattern associated with the plurality of load requests and adjust a prefetch depth according to the access pattern.

Method and apparatus for performing in-situ vacuum-assisted metal to glass sealing

Patent Kramer, Daniel P. (Dayton, OH); Massey, Richard T. (Hamilton, OH)

A method and apparatus for assembling and fusing glass to metal in a glass-metal electrical component is disclosed. The component includes a metallic shell formed with upper and lower cylindrical recesses connected together by longitudinal passages, a pair of metal rings and plural metal pins assembled to define electrical feed-throughs. The component parts are assembled on a fixture having a sleeve-like projection and a central mounting projection establishing concentric nesting surfaces to which the metal rings are slip-fitted in concentric alignment with each other spaced from sidewalls of the lower recess. The pins are in electrical contact with the metalmore »« less

Apparatus and method for performing two-frequency interferometry

Patent Johnston, Roger G. (Los Alamos, NM)

The present apparatus includes a two-frequency, Zeeman-effect laser and matched, doubly refracting crystals in the construction of an accurate interferometer. Unlike other interferometric devices, the subject invention exhibits excellent phase stability owing to the use of single piece means for producing parallel interferometer arms, making the interferometer relatively insensitive to thermal and mechanical instabilities. Interferometers respond to differences in optical path length between their two arms. Unlike many interferometric techniques, which require the measurement of the location of interference fringes in a brightly illuminated background, the present invention permits the determination of the optical path length difference by measuring themore »« less

Apparatus and method for performing electrodynamic focusing on a microchip

Patent Ramsey, John Michael (Knoxville, TN); Jacobson, Stephen C. (Knoxville, TN)

A microchip device includes a focusing channel, in which an electric field strength established in the focusing channel is controlled relative to an electric field strength established in a material transport channel segment to spatially focus the material traversing the material transport channel segment.
