摘要:
A control apparatus, control method and computer readable article of manufacture for controlling data. The control apparatus includes a data storage unit; a plurality of entry storage units, and a plurality of registration units. The data storage unit stores data. Each of the entry storage units stores an entry for registering a pointer to data. If each of the registration units receives an instruction for registering data, then each registration unit (i) searches the entry storage units for an entry storage unit having an empty entry, (ii) registers a pointer to the data to be registered in the retrieved entry storage unit and (iii) stores the data to be registered and identification information of the retrieved entry storage unit in the data storage unit in such a manner that the data to be registered and the identification information is associated with each other.

Multiple application threads write to the same file in parallel. The file is written to on a file cluster-by-file cluster basis. For each file cluster of a number of file clusters of the file, a block of a memory cluster is allocated to an application thread, where the memory cluster corresponds to the file cluster, and the block is written to by the application thread until the block is finished, until all the blocks of the memory cluster are finished. A block may be finished where the application thread has completely written to the block, or the application thread has no further data to write to the block. Thereafter, the memory cluster is registered within a queue, from which it is read by a file writer thread, which writes the memory cluster to the file cluster. Each application thread that is to write to the file performs this process.

A method of managing a multithreaded computer system comprises instantiating, in response to each transaction initiated by a first thread of a plurality of threads, a timer object including a scheduled expiration time and a set of timeout handling information for the transaction in storage local to the first thread; registering, in response to each passing of a fixed time interval, each timer object in the storage local to the first thread for which the scheduled expiration time is earlier than the fixed time interval added to a current time in a timer processing component by adding a pointer referencing the timer object to a data structure managed by the timer processing component; and managing each timer object corresponding to a transaction initiated by the first thread that is not registered in the timer processing component in the storage local to the first thread. The timer processing component regularly processes each timer object referenced by the data structure for which the scheduled expiration time value is not earlier than the current time in accordance with the set of timeout handling information of the timer object.

A server device, methods and a computer program product operating in response to a request received from a client. A request storage device in system memory space with a request storage region stores a request received from a client in association with identification information. An identification information storage region contains a request that is waiting to be processed. An identification information storage unit retrieves at least one request waiting to be processed from the request storage region if the number of identification information pieces stored in the identification information storage region has declined to a reference number or below, and then stores retrieved request identification information in the identification information storage region Multiple request processors operate in parallel, each acquiring identification information from the identification information storage region, a request identified by the acquired identification information from the request storage region, and performing processing in response to the acquired request.

Compiler apparatus, methods and systems for optimizing exception handling in a program. An example apparatus comprises an exception handler detection section for detecting, from exception handlers that catch exceptions thrown in the program, a multiple-catching exception handler that catches a plurality of different exceptions and rethrow the caught exceptions; an exception selection section for selecting a set of exceptions that are to be shifted to common processing through rethrow of the exception by the multiple-catching exception handler from among the plurality of exceptions caught by the detected multiple-catching exception handler; and an exception handler throw section for throwing a clone exception handler that catches the set of exceptions selected by the exception selection section instead of the multiple-catching exception handler and shifting it to common processing.
摘要:
In a multiprocessor computer system, a lock operation is maintained with a thread using non-atomic instructions. Identifiers are assigned to each thread. Flags in conjunction with the thread identifiers are used to determine the continuity of the lock with a thread. However, in the event continuity of the lock with the thread ceases, a compare-and-swap operation is executed to reset the lock with the same thread or another thread. Similarly, in the event there has been a collision between two or more threads requesting the lock, a compare-and-swap operation is executed to assign the lock to one of the requesting threads. Accordingly, prolonged ownership of a lock operation by a thread is encouraged to mitigate use of atomic operations in granting of the lock to a non-owning thread.
