Special issue on programming models, systems software, and tools for High-End Computing

Guest Editors’ Introduction

High-End Computing (HEC) has become a strategic tool in all aspects of scientific discovery and innovation. HEC-enabled simulations have been widely considered a third pillar of science along with theory and experimentation. In recent years, we have observed a proliferation of advanced HEC architectures including multi- and many-core systems, alternative architectures and accelerators, data-intensive computing systems, high-speed network architectures, and integrated computing platforms. These

In this special issue, we compiled a collection of nine of the best papers from the 2012 International Workshop on Parallel Programming Models and Systems Software for High-End Computing Systems (P2S2).

In “Toward Balanced and Sustainable Job Scheduling for Production Supercomputers”, Tang et al. were motivated by practical issues of conflicting goals and changing workloads in HEC scheduling and propose novel scheduling strategies to achieve a balanced and sustainable job scheduling. The
