摘要： Memory segments are allocated for a classloader to store class information, such as by selecting an allocation approach based on classloader type. In a first approach, in response to each request, a segment having a fixed size is allocated. In a second approach, in response to a first request, a first segment having a size equal to an amount of memory needed to store information related to the request is allocated. In response to a second request, a second segment having a second size is allocated, and in response to a third request, a third segment having a third size greater than the second size is allocated. In a third approach, in response to the first request, a first segment having a first size is allocated. In response to a second request, a second segment having a second size greater than the first size is allocated.

摘要： A system of the present invention includes a storage device for distinguishably storing old objects that are objects having existed for not less than a predetermined period since being generated and new objects that are objects having existed for less than the predetermined period since being generated. Then, a new object that has existed for less than the predetermined period since being generated is selected from the storage device, and an old object having the same content as the selected new object is searched for. If such an old object is not found, the selected new object is newly stored as an old object in the storage device. If the old object is found, a reference to the selected new object is integrated with a reference to the found old object. If the old object is stored, the reference to the selected new object is changed to a reference to the stored old object.

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： 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.
摘要翻译： 在多处理器计算机系统中，使用非原子指令的线程来维护锁定操作。 标识符分配给每个线程。 与线程标识符一起使用的标志用于确定带有线程的锁的连续性。 但是，在线程的锁定的连续性停止的情况下，执行比较和交换操作以使用相同的线程或其他线程重置锁定。 类似地，如果两个或多个请求锁的线程之间发生冲突，则执行比较和交换操作以将锁分配给请求线程之一。 因此，鼓励延长线程锁定操作的所有权，以减轻使用原子操作来授予对非拥有线程的锁定。
