The Nas Parallel Benchmarks
TLDR
A new set of benchmarks has been developed for the performance evaluation of highly parallel supercom puters that mimic the computation and data move ment characteristics of large-scale computational fluid dynamics applications.
NAS Parallel Benchmarks

  • 14 July 2010
TLDR
The original NAS Parallel Benchmarks consisted of eight individual bench- mark problems, each of which focused on some aspect of scientific computing, although most of these benchmarks have much broader relevance, since in a much larger sense they are typical of many real-world computing applications.
The HPC Challenge (HPCC) benchmark suite
TLDR
This tutorial will introduce attendees to HPCC, provide tools to examine differences in HPC architectures, and give hands-on training that will hopefully lead to better understanding of parallel environments.
Precimonious: Tuning assistant for floating-point precision
TLDR
Premonious is a dynamic program analysis tool to assist developers in tuning the precision of floating-point programs and recommends a type instantiation that uses lower precision while producing an accurate enough answer without causing exceptions.

TLDR
Advanced techniques for computing an ordered FFT on a computer with external or hierarchical memory that require as few as two passes through the external data set, employ strictly unit stride, long vector transfers between main memory and external storage, and are well suited for vector and parallel computation are described.
The NAS Parallel Benchmarks 2.0
TLDR
A set of implementations of the NAS Parallel Benchmarks based on Fortran 77 and the MPI message passing standard are described, which approximate the performance a typical user can expect for a portable parallel program on a distributed memory computer.
ARPREC: An arbitrary precision computation package
TLDR
A new software package for performing arithmetic with an arbitrarily high level of numeric precision, based on the earlier MPFUN package, enhanced with special IEEE floating-point numerical techniques and several new functions is described.
NAS parallel benchmark results
TLDR
The performance results of various systems using the NAS parallel benchmarks are presented and these results represent the best results that have been reported to the authors for the specific systems listed.
Introduction to the HPC Challenge Benchmark Suite
TLDR
The HPC Challenge benchmark suite is designed to augment the Top500 list, providing benchmarks that bound the performance of many real applications as a function of memory access characteristics e.g., spatial and temporal locality, and providing a framework for including additional tests.
