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.

摘要： Information processing apparatus, including occurrence number counter counting events that occurred in each of a plurality of CPUs. Apparatus performs functions of; storing accumulated occurrence number of events, which occurred while the thread is being executed by each of the CPUs, in a thread storage area of the thread associating accumulated occurrence number with CPU; storing, in the thread storage area, a value of occurrence number counter of the CPU, the value having been counted before the thread is resumed by the CPU; and adding, to accumulated occurrence number which has been stored in accumulated number storing unit while corresponding to the CPU, a difference value obtained by subtracting a counter value, which has been stored in the start-time number storing unit of the thread, from a counter value of the occurrence number counter of the CPU, in a case where the CPU terminates an execution of the thread.

摘要： A method and system are provided for starting a new JAVA application while eliminating overhead associated therewith. The new JAVA application is created from a memory image of an initialized JAVA application. The memory image of the process which is executing the initialized JAVA application is copied to enable the memory image to be observed by the new JAVA application. In addition, to copying the memory image, the states of system resources and operating system monitors not present in the copied memory image are recreated on the JAVA application.

摘要： A technique for comprehensively acquiring calling-context information at a low cost. Call site IDs are held for each thread as a call history and used as context information. At the time of calling a method, the call history existing in a current frame is shifted left, and stacked in a new frame, with the call site ID of the call site put in the lower bits. At the time of returning from the method, the value of the original call history is returned by returning the frame. At the time of performing a virtual call, call history information is recorded into a call position profile table used to identify a method to be inlined at the time of performing JIT compiling, in addition to determined jump destination information and the number of calls.

摘要： A database system that issues a reference transaction by designating a time stamp. Data structures are provided for making an inquiry about the latest value at a designated time using a database in which values and information on times associated with the individual values are contained in a table. One of the data structures includes, for each of IDs associated with the values in the database, at least one time stamp that is sorted in chronological order (hereinafter referred to as a first time stamp); values belonging to the individual first time stamps; and a pointer that designates one of the first time stamps, the first time stamps indicating the times when the values become valid. The other of the data structures includes, for each of the IDs, the designated first time stamp and a value belonging to the designated first time stamp.
