A plethora of optimized mutex lock algorithms have been designed over the past 25 years to
mitigate performance bottlenecks related to critical sections and locks. Unfortunately, there is …

Elasticity is an essential feature of cloud computing, which allows users to dynamically add
or remove resources in response to workload changes. However, building applications that …

Irregular applications comprise an increasingly important workload domain for many fields,
including bioinformatics, chemistry, physics, social sciences and machine learning …

Transaction performs lock and unlocking operations on the data items required in its
execution. These operations on the data items are important in order to maintain consistency …

Symmetric Shared-memory multiprocessor~(SMP) is the most widely used implementation
of high-performance multi-core processors. It offers a uniform shared memory view that …

Classic test-and-test (TS) mutual exclusion locks are simple, and enjoy high performance
and low latency of ownership transfer under light or no contention. They do not, however …

In this article, we present mutable locks, a synchronization construct with the same semantic
of traditional locks (such as spin locks or sleep locks), but with a self‐tuned optimized trade …

The classic ticket lock is simple and compact, consisting of ticket and grant fields. Arriving
threads atomically fetch-and-increment ticket to obtain an assigned ticket value, and then …

As system complexity grows, embedded operating systems increasingly face the challenge
to adhere to various non-functional constraints, such as response times and power limits …

The paper presents a multi-version granular structure, an extension of the multiple
granularity locking mechanisms. The existing hierarchical locking carries out its operation at …
