摘要:
A multiprocessor computer system includes a plurality of processor nodes, a memory, and an interconnect network connecting the plurality of processor nodes to the memory. The memory includes a plurality of lines and a cache coherence directory structure. The plurality of lines includes a first line. The cache coherence directory structure includes a plurality of directory structure entries. Each directory structure entry includes processor pointer information indicating the processor nodes that have cached copies of the first line. The processor pointer information includes a plurality n of bit vectors, where n is an integer greater than one. The n bit vectors define a matrix having a number of locations equal to the product of the number of bits in each of the n bit vectors. The number of locations is greater than the number of processor nodes and each of the processor nodes is mapped to a corresponding one of the locations wherein the locations corresponding to the processor nodes are dispersed in the matrix in an at least partially noncontiguous manner.

A multiprocessor computer system includes a method and system of handling invalidation requests to a plurality of alias processors not sharing a line of memory in a computer system. A memory directory interface unit receives an invalidation request for a shared line of memory shared in a plurality of sharing processors. A superset of processors in the computer system that includes each of the sharing processors is determined that includes at least one alias processor not sharing the shared line of memory. An invalidation message is transmitted to each processor in the superset of processors. The number Na of alias processors in the superset of processors is determined and a superacknowledgement message is provided that is equivalent to acknowledging receipt of Na invalidation messages.

Certain substituted anthracene-type compounds have been found to be useful as isotropic dyestuffs in guest-host combinations with nematic, cholesteric and smectic liquid crystals and other well-known dichroic dyestuffs. By "isotropic" it is meant that the disclosed dyestuffs have optical order parameters (S) very close to zero. Use of the disclosed isotropic dyestuffs with additional well-known dichroic dyes in liquid crystal display devices, provides displays which alter between one colored state and another, depending upon the presence or absence of an electric field across the display.

An inhibitor removing bath for effecting color formation in a color positive development process which bath comprises a color accelerating agent, a contrast control agent and a pH control agent. The inhibitor removing bath may further contain in a preferred embodiment a color reversal agent. A complete color photographic development process using this inhibitor removing bath is found to provide color positive transparencies of excellent quality.

The present invention provides alignment and ordering of vector elements for SIMD processing. In the alignment of vector elements for SIMD processing, one vector is loaded from a memory unit into a first register and another vector is loaded from the memory unit into a second register. The first vector contains a first byte of an aligned vector to be generated. Then, a starting byte specifying the first byte of an aligned vector is determined. Next, a vector is extracted from the first register and the second register beginning from the first bit in the first byte of the first register continuing through the bits in the second register. Finally, the extracted vector is replicated into a third register such that the third register contains a plurality of elements aligned for SIMD processing. In the ordering of vector elements for SIMD processing, a first vector is loaded from a memory unit into a first register and a second vector is loaded from the memory unit into a second register. Then, a subset of elements are selected from the first register and the second register. The elements from the subset are then replicated into the elements in the third register in a particular order suitable for subsequent SIMD vector processing.
摘要:
Organic light emitting diode (OLED) devices are one of the most promising alternatives to liquid crystal displays (LCDs) for flat panel display (FPD) applications. The OLED technique is based on organic semiconductors used either as hole- or electron transporting materials or as an emitter. Working on common problems of performance and life time in OLED preparation, improved charge transport molecules and polymers such as triarylamine- and poly(para-phenylene)-have been developed. Some useful materials include: (1) cyclic triarylamine-derivatives possessing enhanced glass transition temperatures; (2) triarylamine based low molecular mass hole-transport molecules and hole-transport polymers with pendant oxetane groups for processing out of solution and subsequent cross-linking; and (3) fluorenyl-segmented poly(para-phenylene)s with defined electrochemical properties. Provided is a polymer precursor that is useful as a hole transport polymer in OLED and other organic electronic devices.
