摘要： A system for conditional memory ordering implemented in a multiprocessor environment. A conditional memory ordering instruction executes locally using a release vector containing release numbers for each processor in the system. The instruction first determines whether a processor identifier of the release number is associated with the current processor. Where it is not, a conditional registered is examined and appropriate remote synchronization operations are commanded where necessary.

摘要： A system, method and computer program product for processing overflow transactions in a transactional memory system. The transactional memory system is provided in a multiprocessing system having one or more processor devices and a shared memory storage system, and implements a best effort hardware transactional memory system. The method includes acquiring, by a requesting processor, lockbits associated with a memory structure of the shared memory storage system to be reserved for an overflowing transaction. The lockbits determine the granularity at which memory reservations for an overflow transaction are recorded. The method includes implementation of control mechanism for controlling concurrency between overflowing and non-overflowing transactions requested by processor devices in the multiprocessing system, the method enabling only one overflowing transaction to execute at a time in the multiprocessing system.

摘要： A method and apparatus for conditional memory ordering are disclosed. The cost of memory ordering is reduced by determining circumstances in which a memory ordering operation is unnecessary and avoiding the overheads of these operations by reducing the frequency of invoking hardware memory ordering mechanisms. Hardware instructions for implementing a conditional memory ordering method and apparatus is described which may be implemented in a multiprocessor environment. The conditional memory ordering instruction executes locally using a release vector containing release numbers for each processor in the system. The instruction first determines whether a processor identifier of the release number is associated with the current processor. Where it is not, a conditional register is examined and appropriate remote synchronization operations are commanded where necessary.

摘要： A system and method to trigger synchronization and validation actions at memory access, in one aspect, identifies a storage class associated with a region of shared memory being accessed by a thread, determines whether the thread holds the storage class and acquires the storage class if the thread does not hold the storage class, identifies a programmable action associated with the storage class and the thread, and triggers the programmable action. One or more storage classes are respectively associated with one or more regions of shared memory. An array of storage classes associated with a thread holds one or more storage classes acquired by the thread. A configurable action table associated with a thread indicates one or more programmable actions associated with a storage class.
