Notified access in coarray-based hydrodynamics applications on many-core architectures: Design and performance

Performance analysis of a 3D unstructured mesh hydrodynamics code on multi- and many-core architectures

Several next generation high performance computing platforms are or will be based on the so-called many-core architectures, which represent a significant departure from commodity multi-core architectures. A key issue in transitioning large-scale simulation codes from multi-core to many-core systems is closing the serial performance gap, that is, overcoming the large difference in single-core pe...

Many-Task Computing on Many-Core Architectures

Many-Task Computing (MTC) is a common scenario for multiple parallel systems, such as cluster, grids, cloud and supercomputers, but it is not so popular in shared memory parallel processors. In this sense and given the spectacular growth in performance and in number of cores integrated in many-core architectures, the study of MTC on such architectures is becoming more and more relevant. In this...

A Cross-Core Performance Model for Heterogeneous Many-Core Architectures

An accurate performance predictor to identify the most suitable core-architecture to execute each thread/workload in a heterogeneous many-core structure is proposed. The devised predictor is based on a linear regression model that considers several different parameters of the many-core processor architectures, including the cache size, issuewidth, re-order buffer size, load/store queues size, e...
