Rather than always placing a remote lock in a queue at the tail, a remote lock can be placed further up in the queue, and possibly be interleaved with local locks. As a result, remote ... 09/07/06 - 20060200609 - Hardware semaphore intended for a multi-processor system The invention relates to a method in a hardware semaphore lock (L1-LN) intended for a multi-processor system, which semaphore lock (L1-LN) protects a shared resource (R1-RN) in connection with the system in such a way that only a process which has reserved the semaphore lock (L1-LN) and has thus become ... 07/27/06 - 20060168381 - Apparatus and method for controlling resource transfers in a logically partitioned computer system A resource and partition manager of the preferred embodiments includes a lock mechanism that operates on a plurality of locks that control access to individual I/O slots. The resource and partition manager uses the lock mechanism to obtain a lock on an I/O slot when transferring control of the I/O ... 06/22/06 - 20060136637 - Locking multiple resources in a distributed environment A method and system that creates and maintains lock properties for a resource or object in a distributed environment. The method and system creates and/or updates lock objects to relate to multiple locks, i.e., multiple resources. The method and system creates and maintains lock properties for a resource or object ... 06/22/06 - 20060136636 - System and method for resolving conflicts of re-locking resources A system for resolving conflicts of re-locking resources includes: a plurality of system resources (10), a memory (11), and a central processing unit (12). The memory includes a data storing region (110), a re-lock resolving module (111), and an application storing region (112) for storing a plurality of function applications. ... 05/18/06 - 20060106964 - Apparatus, system, and method of channel grouping for multipath lock facility connection paths An apparatus, system, and method are disclosed for grouping connection paths for lock attention data. A grouping request module is included to receive a request to establish a group of connection paths. Each connection path is configured to communicate lock attention data between a host and a control unit. The ... 03/23/06 - 20060064527 - Adaptive message delivery system A device monitors a system's available resources and produces either a deferred notification or an instant notification based on a comparison with an established threshold. The threshold may be adjusted if current or anticipated system resource utilization changes. Changes to the threshold may result in deferred notifications being removed from ... 02/16/06 - 20060036790 - Method, system, and program for returning attention to a processing system requesting a lock Provided are method, system, and program for returning attention to a processing system requesting a lock. A lock request for a resource is received from the processing system. Indication is made of a connection path on which the processing system initially communicated an establish request to establish a connection. Attention ... 02/16/06 - 20060036789 - Method to switch the lock-bits combination used to lock a page table entry upon receiving system reset exceptions A method, system, and computer instructions for changing the lock-bits combination used to lock a resource upon receiving a system reset exception. The present invention forces the software to use different lock-bits combinations based on the number of occurrences of system reset exceptions. When a system reset exception is received, ... 12/29/05 - 20050289270 - Control of the execution of a program A method and a circuit of automatic control of the execution of a program by a microprocessor, including: assigning a digital decrement or increment to at least one function of the program; assigning a digital increment, respectively decrement, to at least one section considered as critical as to the program ... 12/22/05 - 20050283553 - Event based operating system, method, and apparatus for instrumentation and control systems A method for operating a controller having a number of timers to thereby control a plurality of events greater than the number of timers, includes, between clock ticks, receiving one or more signals from sensors, switches, executing programs, or a combination therefore that initiate one or more timed events. After ... 11/03/05 - 20050246462 - Maintaining time-date information for syncing low fidelity devices Generally, the present invention provides for a distributed computing system that is capable of associating time-date information with a property value in the database. The distributed computing system has a device that stores properties in a database without corresponding time-date fields, and thus is considered a low fidelity or legacy ... 11/03/05 - 20050246461 - Scheduling threads in a multi-processor computer Scheduling threads in a multi-processor computer system including establishing an interrupt threshold for a thread, where the interrupt threshold represents a maximum permissible number of interrupts during thread execution on a processor; executing the thread on a current processor, where the thread has thread affinity for one or more processors ... 10/27/05 - 20050240699 - Safe process deactivation One embodiment disclosed relates to a method of deactivating a process by a computer operating system. Threads of the process that are currently suspendable are moved to a stopped state. A process-wide deactivation operation is initiated. The process-wide deactivation operation is called by outstanding threads of the process when the ... 10/20/05 - 20050235085 - Digital controller and engine controller using the same The digital controller includes an interrupt generator for generating an interrupt signal at predetermined intervals, a task execution controller for controlling execution of a control task in response to an interrupt signal generated by the interrupt generator, and an interrupt disabler for, when the control task is being executed, disabling ... 10/13/05 - 20050228917 - Novel structure and method for interrupt detection and processing An electronic system includes a processor and an interrupt structure. The interrupt structure handles interrupt information such as interrupt requests, interrupt function types, and interrupt data without involving the processor. The processor performs interrupt functions according to the interrupt information at times independent from the times the interrupt requests are ... 10/13/05 - 20050228916 - Controller and resource management system and method with improved security for independently controlling and managing a computer system A controller and resource management system and method with improved security for independently controlling and managing a computer system is provided.
