  • Patent number: 6480918
    Abstract: The processors in a multiprocessor computer system are grouped into nodes. The processors can request a lock, but the lock is granted to only one processor at any given time to provide exclusive processor access to the resource protected by the lock. When a processor releases the lock, the lock is made available to another processor at the same node, even though a processor at a different node may have requested the lock earlier. To maintain fairness, the lock is forced to another node after granting a certain number of consecutive requests at a node or after a certain time period. In one embodiment, a specialized data structure representing a lock request from a processor at a particular node is placed into a queue. A later requesting processor can acquire a preemptive position in the queue by spinning on a data structure already in the queue if the data structure corresponds to the processor's node.

  • Patent number: 6423835
    Abstract: The present invention relates to novel polypeptides comprising a unique “chlamydial-specific” primary structural conformation and one or more of the biological properties of eukaryotic or prokaryotic stress-response proteins which are characterized by being the expressed products of an endogenous or exogenous DNA sequence in a eukaryotic or prokaryotic host cell. Sequences coding for part or all of the amino acid residues of the chlamydial HypA or HypB protein or for analogs thereof may be incorporated into autonomously replicating vectors employed to transform or transfect suitable procaryotic or eukaryotic host cells such as bacteria or vertebrate cells in culture. The HypB protein is a member of the family of stress response proteins referred to as HSP60. Products of expression of the DNA sequences display the identical physical, immunological, and histological properties as the chlamydial proteins isolated from natural, non-recombinant, organisms.

  • Patent number: 6418517
    Abstract: A method for scheduling functions for execution immediately or later in time by the scheduling processor or another processor of a shared memory multiprocessor computer system such as a NUMA machine. Associated with each of the multiple processors is a data structure for scheduling the execution of specified functions by the processor. These multiple data structures with associated locks allow for simultaneous access by processors to their data structures and thereby avoid the bottleneck inherent in the prior approach of providing only a single, global data structure for all processors. In addition, the method allows any processor to call a scheduling function to add a specified function to the data structure of any of the processors. Processor loads are balanced by moving scheduled specified functions from one processor to another. Scheduled functions can also be moved from one processor to another to allow a processor to be taken offline for service.

  • Patent number: 6404931
    Abstract: A method of constructing a code book for groupings of symbols drawn from an alphabet, in which variable-sized groups of symbols are each assigned a variable length code based on probability of occurrence of symbol groupings. Code book entries are added by tentatively extending the high probability groupings with symbols from the alphabet. Code book size is restrained by identification of identify high probability symbol groupings, such that low probability groupings are combined into a single code book entry. Probability of occurrence for each entry is tracked. Extension and combination is repeated until a code book of predetermined size is reached. Each code book entry is assigned an entropy-type code according to the probability associated with each book entry.

  • Patent number: 6389513
    Abstract: A buffer cache management structure, or metadata, for a computer system such as a NUMA (non-uniform memory access) machine, wherein physical main memory is distributed and shared among separate memories. The memories reside on separate nodes that are connected by a system interconnect. The buffer cache metadata is partitioned into portions that each include a set of one or more management data structures such as hash queues that keep track of disk blocks cached in the buffer cache. Each set of management data structures is stored entirely within one memory. A first process performs operations on the buffer cache metadata by determining, from an attribute of a data block requested by the process, in which memory a portion of the metadata associated with the data block is stored. The process then determines if the memory containing the metadata portion is local to the process. If so, the first process performs the operation.

  • Patent number: 6353923
    Abstract: An active debugging environment for debugging a virtual application that contains program language code from multiple compiled and/or interpreted programming languages. The active debugging environment is language neutral and host neutral, where the host is a standard content centric script host with language engines for each of the multiple compiled and/or interpreted programming languages represented in the virtual application. The active debugging environment user interface can be of any debug tool interface design. The language neutral and host neutral active debugging environment is facilitated by a process debug manager that catalogs and manages application specific components, and a machine debug manager that catalogs and manages the various applications that comprise a virtual application being run by the script host. The process debug manager and the machine debug manager act as an interface between the language engine specific programming language details and the debug user interface.

  • Patent number: 6308571
    Abstract: A method for determining crook potential of wood is described. One embodiment comprises nondestructively obtaining lengthwise shrinkage rates (from a third party or by direct measurement) of wood and then determining crook potential of the wood based on the lengthwise shrinkage rates. Where the wood comprises lumber, lengthwise shrinkage rate measurements typically are made on at least one major planar surface of the lumber. The method typically comprises determining lengthwise shrinkage rates two or more measuring points separated by a predetermined distance, such as at substantially one-foot intervals along the lumber. Particular embodiments of the present invention determine lengthwise shrinkage rates using infrared radiation, microwave radiation, electricity, ultrasound energy, and combinations thereof Working embodiments of the method use ultrasound energy to determine lengthwise shrinkage rates.
