PyACTS: a high-level framework for fast development of high performance applications

Abstract: Software reusability has proven to be an effective practice to speed-up the development of complex high-performance scientific and engineering applications. We promote the reuse of high quality software and general purpose libraries through the Advance CompuTational Software (ACTS) Collection. ACTS tools have continued to provide solutions to many of today's computational problems. In addition, ACTS tools have been successfully ported to a variety of computer platforms; therefore tremendously facilitating the porting of applications that rely on ACTS functionalities. In this contribution we discuss a high-level user interface that provides a faster code prototype and user familiarization with ACTS tools. The high-level user interfaces have been built using Python. Here we focus on Python based interfaces to ScaLAPACK, the PyScaLAPACK component of PyACTS. We briefly introduce their use, functionalities, and benefits. We illustrate a few simple example of their use, as well as exemplar utilization inside large scientific applications. We also comment on existing Python interfaces to other ACTS tools. We present some comparative performance results of PyACTS based versus direct LAPACK and ScaLAPACK code implementations.

High-level user interfaces for the DOE ACTS collection

Abstract: The ACTS collection project comprises a set of state-of-theart software tools to speed up the development of High-Performance Computing Applications in science and engineering. We look at the development of High Level user interfaces using scripting languages like Python, to facilitate the access to ACTS technology to a wide community of computational scientists. PyACTS is our main project here, but we also visit other efforts within the community of developers of ACTS tools.
