Adaptive Concurrency Control for Transactional Memory
Transactional applications may exhibit fluctuating amounts of contention during execution. Excessive numbers of threads executing transactions can produce phases with a high transaction abort ratio. while few threads executing transactions will under-perform in phases with low contention. This paper presents the first application of adaptive concurrency control to TM in order to dynamically adj...
متن کاملVallejo - Hybrid Transactional Memory with Pessimistic Concurrency Control Hybrid Transactional Memory with Pessimistic Concurrency Control1
Transactional Memory (TM) intends to simplify the design and implementation of the sharedmemory data structures used in parallel software. Many Software TM systems are based on writerlocks to protect the data being modified. Such implementations can suffer from the “privatization” problem, in which transactional and non-transactional accesses to the same location can lead to inconsistent result...
متن کاملAdvanced Concurrency Control for Transactional Memory Using Transaction Commit Rate
Concurrency control for Transactional Memory (TM) is investigated as a means for improving resource usage by adjusting dynamically the number of threads concurrently executing transactions. The proposed control system takes as feedback the measured Transaction Commit Rate to adjust the concurrency. Through an extensive evaluation, a new Concurrency Control Algorithm (CCA), called P-only Concurr...
متن کاملDependence-Aware Transactional Memory
Transactional memory is a promising programming model to enable high performance programs with reasonable programmer effort on the parallel architectures favored by modern processor manufacturers. This paper introduces dependence-aware transactions, a new method for maintaining the conflict serializability safety property of memory transactions while allowing significant freedom for an implemen...
متن کاملScalable NUMA-aware Blocking Synchronization Primitives
Application scalability is a critical aspect to efficiently use NUMA machines with many cores. To achieve that, various techniques ranging from task placement to data sharding are used in practice. However, from the perspective of an operating system, these techniques often do not work as expected because various subsystems in the OS interact and share data structures among themselves, resultin...
