摘要： A method, apparatus, and computer readable article of manufacture for tracing, on the basis of a key, an index created using a tree structure to access data. The method includes: searching the tree structure to reach a target node that can be associated with the key without acquiring a lock on the root node and on an internal node; setting the target node as a current node when the target node is a leaf node; moving the search to a node at a lower layer when the target node is an internal node by tracing an edge in the tree structure to reach a leaf node and setting the leaf node as the current node; and associating the key with the leaf node specified as the current node by acquiring a lock on the leaf node specified as the current node, thereby accessing the data.

摘要： A memory control apparatus which controls access to a shared memory for each transaction. The apparatus includes a management unit that stores versions of data stored in the shared memory, a log storage unit that stores an update entry including a version of data subjected to an update operation in response to execution of an update operation on the shared memory in processing each transaction, and a control unit that writes a result of processing corresponding to execution of a relevant update operation to the shared memory when a request to commit a transaction has been given, and a relevant update entry version matches a corresponding version stored in the management unit, or re-executes the update operation and writes a result of re-execution to the shared memory when the update entry version does not match the corresponding version in the management unit.

摘要： Method for isolating an object that has not been accessed for a certain period of time in a virtual memory space. When a garbage collection operates on a computer, the following steps are executed: detecting the object which has not been accessed for a certain period of time as a non-access object; moving the non-access object to a newly reserved virtual memory region when a certain time period elapses after detecting the non-access object; and setting the newly reserved virtual memory region to be an inaccessible region so that the garbage collection does not access the inaccessible region after a certain further time period elapses after moving the non-access object to the newly reserved virtual memory region.

摘要： The present invention relates to allocating registers to variables in order to compile a program. In an embodiment of the present invention a compiler apparatus stores interference information indicating an interference relationship between variables, selects a register and allocates the register to each variables in accordance with a predetermined procedure, without allocating the same register to a set of variables having interference relationships. The compiler further replaces multiple variables having the same register allocated thereto with a new variable and generates an interference relationship by merging the interference relationships each concerning one of multiple variables. The compiler further updates interference information according to the generated interference relationship and allocates to each variable in the program using the new variable a register, selected in accordance with the predetermined procedure without allocating the same register to a set of variables having the interference relationships, based on the updated interference information.

摘要： One or more embodiments provide a technique of improving the conventional thread-local garbage collection (GC) so as to avoid fragmentation. A memory management device having a plurality of processors implementing transactional memory includes a write barrier processing unit which, when performing write barrier in response to initiation of a pointer write operation, registers an object that is located outside of a local area and that has a pointer pointing to an object located in the local area in a write log so as to set it as a target of conflict detection, and a garbage collector which, provided that no conflict is detected, copies a live shared object in the local area to the outside of the local area and collects any unwanted object irrespective of whether it is shared or not.
