To write code, developers stitch together patterns, like API protocols or data structure
traversals. Discovering these patterns can identify inconsistencies in code or opportunities to …

The rapid evolution of HPC systems brings us a high computational capability. However, it is
getting harder to exploit the potential of an HPC system due to the increases in system …

Refactoring has become an effective approach to convert sequential programs into
concurrent programs. Many refactoring algorithms and tools are proposed to assist …

Aiming at keeping performance portability of practical applications even in the exascale
computing era, this paper presents a concept of HPC refactoring, and the design of the HPC …

Abstraction based programming has been traditionally seen as an approach that improves
software quality at the cost of losing performance. In this paper, we explore the cost of …

Significant performance gains can be achieved by using hardware architectures that
integrate GPUs with conventional CPUs to form a hybrid and highly parallel computational …

Historically, the creators of parallel programming models have employed two different
approaches to make their models available to developers: either by providing a library with …

During maintenance, developers spend a lot of time transforming existing code: refactoring,
optimizing, and adding checks to make it more robust. Much of this work is the drudgery of …

Considerable recent attention has been given to the problem of porting existing code to
heterogeneous computing architectures, such as GPUs. In this paper, we describe a novel …

This paper presents" Mojave," a set of plug-ins for the Eclipse Integrated Development
Environment (IDE), which provides a unified interface for HPC code development and job …
