This book describes several approaches to adaptability that are applied for the optimization
of parallel applications, such as thread-level parallelism exploitation and dynamic voltage …

The ongoing effort to reach the exascale computing barrier has led to a myriad of research
and publications in the topic of alternative energy-efficient architectures, such as ARM, for …

NUMA systems have become commonly used in HPC. However, to fully take advantage of
these systems, the right thread-to-core allocation and page placement are essential. On top …

Many parallel applications do not scale as the number of threads increases, which means
that using the maximum number of threads will not always deliver the best outcome in …

This paper presents PAMPAR, a new benchmark to evaluate the performance and energy
consumption of different Parallel Programming Interfaces (PPIs). The benchmark is …

Considering that multithreaded applications may be implemented using several
programming languages and paradigms, in this work we show how they influence …

Asymmetric multicore processors (AMP) combine high-performance cores with more energy-
efficient ones, capitalizing on the diverse performance demands of modern devices (eg …

Many parallel applications do not scale as the number of threads increases, which means
that using the maximum number of threads will not always deliver the best outcome in …

To satisfy the rising performance demands of modern applications, the number of cores in a
single chip package has been increasing. However, the power dissipated and temperature …

This paper presents a new benchmark to evaluate performance and energy consumption of
different Parallel Programming Interfaces (PPIs). The benchmark is composed of 11 …
