Scalability Evaluation of Barrier Algorithms for OpenMP
OpenMP relies heavily on barrier synchronization to coordinate the work of threads that are performing the computations in a parallel region. A good implementation of barriers is ...

Algorithmic optimizations of a conjugate gradient solver on shared memory architectures
OpenMP is an architecture-independent language for programming in the shared memory model. OpenMP is designed to be simple and in terms of programming abstractions. Unfortunately,...

Phaser accumulators: A new reduction construct for dynamic parallelism
A reduction is a computation in which a common operation, such as a sum, is to be performed across multiple pieces of data, each supplied by a separate task. We introduce phaser a...

Efficiency and scalability of barrier synchronization on NoC based many-core architectures
Interconnects based on Networks-on-Chip are an appealing solution to address future microprocessor designs where, very likely, hundreds of cores will be connected on a single chip...
