Abstract: The present invention provides a computer implemented method, apparatus, and computer usable program code for compiling instructions to manage a cache system. Loop constructs are analyzed to identify data usage characteristics for cache and prefetching conditions in instructions to form identified prefetch conditions. A set of control instructions are inserted into the instructions based on the data usage characteristics and the identified prefetch conditions to form multiple modified instructions. The set of multiple modified instructions are compiled to generate code for execution to form compiled instructions. The set of control instructions in the compiled instructions form a cache management policy to control movement of data in a memory system during execution of the compiled instructions.

Abstract: Method of making a microstructured optical fiber. Silica glass based soot is deposited on a substrate to form at least a portion of an optical fiber preform by traversing a soot deposition burner with respect to said substrate at a burner traverse rate greater than 3 cm/sec, thereby depositing a layer of soot having a thickness less than 20 microns for each of a plurality of burner passes. At least a portion of the soot preform is then consolidated inside a furnace to remove greater than 50 percent of the air trapped in said soot preform, said consolidating taking place in a gaseous atmosphere containing krypton, nitrogen, or mixtures thereof under conditions which are effective to trap a portion of said gaseous atmosphere in said preform during said consolidation step, thereby forming a consolidated preform which when viewed in cross section will exhibit at least 50 voids therein.

Abstract: A data processing system includes a microprocessor having access to multiple levels of cache memories. The microprocessor executes a main thread compiled from a source code object. The system includes a processor for executing an assist thread also derived from the source code object. The assist thread includes memory reference instructions of the main thread and only those arithmetic instructions required to resolve the memory reference instructions. A scheduler configured to schedule the assist thread in conjunction with the corresponding execution thread is configured to execute the assist thread ahead of the execution thread by a determinable threshold such as the number of main processor cycles or the number of code instructions. The assist thread may execute in the main processor or in a dedicated assist processor that makes direct memory accesses to one of the lower level cache memory elements.

Abstract: A method and apparatus for making an optical fiber preform. The apparatus has an outer wall and an inner wall. The outer wall surrounds the inner wall and the inner wall surrounds an inner cavity of the apparatus. A core rod is deposited in the inner cavity after which particulate glass material, such as glass soot, is deposited in the inner cavity around the core rod. The core rod has at least 10 percent of the final cladding soot already applied thereto. A radially inward pressure is applied against the particulate glass material to pressurize the particulate glass material against the core rod.

Abstract: A method of making an optical fiber preform includes depositing silica glass on the inside of a tube substrate via a plasma chemical vapor deposition (PCVD) operation. The parameters of the PCVD operation are controlled such that the silica glass deposited on the interior of the tube substrate contains a non-periodic array of voids in a cladding region of the optical fiber preform. The optical fiber preform may be used to produce an optical fiber having a core and a void containing cladding. The core of the optical fiber has a first index of refraction and the cladding has a second index of refraction less than that of the core.

The energy absorbing components securing a bottle stored within the container to may inhibit or prevent movement of the bottle within the container.

Abstract: Compressed memory systems are provided to reduce latency associated with accessing compressed memory using stratified compressed memory architectures and memory organization protocols in which a region of compressed main memory is allocated as a direct access memory (DAM) region for storing uncompressed data items. The uncompressed data items in the DAM region can be directly accessed, speculatively, to serve access requests to main memory, requiring access to compressed memory in the event of a DAM miss.

Abstract: Methods of forming an overclad portion of an optical fiber are described which include positioning a core cane member in an overclad tube to form a rod and tube assembly. Thereafter, glass soot pellets are positioned in the rod and tube assembly between the core cane member and an interior sidewall of the overclad tube. The rod and tube assembly is then redrawn under conditions effective to form the overclad tube and the glass soot pellets into a continuous, void-free glass layer surrounding the core cane member at a sintering time tsinter of at least 1800 seconds thereby forming an overclad portion of an optical fiber.

Abstract: Methods, systems, and media for reducing memory latency seen by processors by providing a measure of control over on-chip memory (OCM) management to software applications, implicitly and/or explicitly, via an operating system are contemplated. Many embodiments allow part of the OCM to be managed by software applications via an application program interface (API), and part managed by hardware. Thus, the software applications can provide guidance regarding address ranges to maintain close to the processor to reduce unnecessary latencies typically encountered when dependent upon cache controller policies. Several embodiments utilize a memory internal to the processor or on a processor node so the memory block used for this technique is referred to as OCM.

Abstract: A method of making an optical fiber preform includes depositing silica glass soot on the inside of a substrate tube via a chemical vapor deposition operation. The silica glass soot is consolidated into silica glass under controlled conditions such that the consolidated silica glass on the interior of the substrate tube contains a non-periodic array of gaseous voids in a cladding region of the optical fiber preform. The optical fiber preform may be used to produce an optical fiber having a core and a cladding containing voids formed from the gaseous voids of the cladding region of the optical fiber preform. The core of the optical fiber has a first index of refraction and the cladding has a second index of refraction less than that of the core.

Abstract: An efficient method for selecting a minimal and statistically relevant set of SER sensitive logic devices critical to the SER robustness for a design, through identification by device type, identification nomenclature, connectivity and context. The minimal set of devices comprise the set of fault injection test points using a conventional fault injection test verification environment to establish an SER induced failure rate a logic design. The selection method affords a design independent means to evaluate any design regardless of the origin, source language or documentation by working at the common logic device level “gate-level” netlist format for the design data. The selected set of devices is distilled from the design data by successively filtering the design through a series of heuristic rule-based device identifier computer programs that group and annotate the devices into specific database records.
