In the last three decades a large number of compiler transformations for optimizing programs have been implemented. Most optimization for uniprocessors reduce the number of instructions executed by the program using transformations based on the analysis of scalar quantities and data-flow techniques. In contrast, optimization for

The specific demands of high-performance computing (HPC) often mismatch the assumptions and algorithms provided by legacy operating systems (OS) for common workload mixes. While feature- and application-rich OSes allow for flexible and low-cost hardware configurations, rapid development

is possible when you run ANSYS Mechanical on workstations and servers equipped with an NVIDIA GPU, which is loaded with high performance computing features for technical computing. These GPU-powered systems deliver performance increases that accelerate ANSYS results vs. computing with CPUs alone. To learn

In 1993, a list of the top 500 supercomputer sites worldwide was made available for the first time. Since then, the Top500 list has been published twice a year. The list allows a detailed and well-founded analysis of the state of high-performance computing (HPC). This article summarizes the recent

For decades, the high-performance computing (HPC) community has focused on performance, where performance is defined as speed. To achieve better performance per compute node, microprocessor vendors have not only doubled the number of transistors (and speed) every 18-24 months, but they have also

the U.S. Army and a consortium of university and industry partners, develops and applies high performance computing capabilities to address the Army’s most difficult scientific and engineering challenges. AHPCRC also fosters the education of the next generation of scientists and engineers

Architecture for the Support of High Performance Computing” was sponsored by the National Science Foundation to identify critical research topics in computer architecture as they relate to high performance computing. Following a wide-ranging discus-sion of the computational characteristics

In this lecture we present high performance computing from a programmers perspective. Several approaches to programming high-performance computers are reviewed. Examples are given of extensions to FORTRAN for programming shared-memory systems as well as distributed memory systems. Keywords: High

In 1993 for the first time a list of the top 500-supercomputer sites worldwide has been made available. The Top500 list allows a much more detailed and well-founded analysis of the state of high performance computing. This paper summarizes some of the most important observations about HPC
