Average programmers struggle to solve performance problems in OpenMP programs with
tasks and parallel for-loops. Existing performance analysis tools visualize OpenMP task …

A suite of scalable atomistic simulation programs has been developed for materials research
based on space-time multiresolution algorithms. Design and analysis of parallel algorithms …

Early-bird communication is a communication/computation overlap technique that combines
fine-grained communication with partitioned communication to improve application run-time …

The approach of automatic algorithms transformation into concurrent form is proposed. One
is based on mathematical apparatus of stochastic Petri nets with additional semantic …

Early‐bird communication is a communication/computation overlap technique that leverages
fine‐grained communication to improve application run‐time. Communication is divided …

The task-based programming paradigm offers a portable way of writing parallel applications.
However, it requires tedious tuning of the application for performance. We present a novel …

Grain graphs simplify OpenMP performance analysis by visualizing performance problems
from a fork-join perspective that is familiar to programmers. However, it is tedious to navigate …

This paper presents an alternative to computing the power set in a sequential computing
environment. The algorithms to compute the power set run concurrently on the Stampede2 …

The end of Dennard scaling also brought an end to frequency scaling as a means to
improve performance. Chip manufacturers had to abandon frequency and superscalar …
