NAS Kernels Survey Report

NAS Kernels on the Connection Machine RND-90-005

The NAS Kernel Benchmark Program is a collection of FORTRAN subroutines, or "kernels", which were chosen to be representative of the computational workload of the Numerical Aerodynamic Simulation (NAS) facility located at NASA Ames Research Center. Details of the kernels are provided in [1]. The kernels provide benchmark measures of double precision (64 bit) floating point computation rate and ...

Performance Coupling: Case Studies for Measuring the Interactions of Kernels in Modern Applications

Traditional performance optimization techniques have focused on nding the kernel in an application that is the most time consuming and attempting to optimize it. In this paper we focus on optimization techniques for a more global perspective of the application. In particular, we present a methodolodgy for measuring the interaction or coupling between kernels within an application and describe h...

Titanium Performance and Potential: An NPB Experimental Study

Titanium is an explicitly parallel dialect of Java designed for high-performance scientific programming. We present an overview of the language features and demonstrate their use in the context of the NAS Parallel Benchmarks, a standard suite of common scientific kernels. We argue that parallel languages like Titanium provide greater expressive power than conventional approaches, enabling much ...

Performance Characteristics of OpenMP Constructs, and Applications Benchmarks on a Large Symmetric Multiprocessor

With the increasing popularity of small to large-scale symmetric multiprocessor (SMP) systems, there has been a dire need to have sophisticated, and flexible development and runtime environments for efficient and rapid development of parallel applications. To this end, OpenMP has emerged as the standard for parallel programming on shared-memory systems. It is very important to evaluate the perf...
