Despite Figure 1 clearly shows the visible increase in length of the state-of-the-art hardware and the design complexity, the 37cm between an XC40 compute module (front) and an system was built in a matter of weeks and was returned to XC50 compute module (rear). fully operational service for CSCS user communities in less than two months, while at the same time providing significant improvements in energy efficiency. This paper focuses on the innovative features of the Piz Daint system that not only resulted in an adaptive, scalable and stable platform but also offers a very high level of operational robustness for a complex ecosystem. -

Cray Product Installation and Configuration
Cray Product Installation and Configuration Scott E. Grabow, Silicon Graphics, 655F Lone Oak Drive, Eagan, MN 55121, [email protected] ABSTRACT: The Common Installation Tool (CIT) has had a large impact upon the installation process for Cray software. The migration to CIT for installation has yielded a large number of questions about the methodology for installing new software via CIT. This document discusses the installation process with CIT and how CIT’s introduction has brought about changes to our installation process and documentation. 1 Introduction • Provide a complete replacement approach rather than an incremental software approach or a mods based release The Common Installation Tool (CIT) has made a dramatic change to the processes and manuals for installation of UNICOS • Provide a better way to ensure that relocatable and source and asynchronous products. This document is divided into four files match on site after an install major sections dealing with the changes and the impacts of the • Reduce the amount of time to do an install installation process. • Support single source upgrade option for all systems 2 Changes made between UNICOS 9.0 and Some customers have expressed that the UNICOS 9.0 instal- UNICOS 10.0/UNICOS/mk lation process is rather hard to understand initially due to the incremental software approach, the number of packages needed With the release of UNICOS 9.2 and UNICOS/mk the pack- to be loaded, and when these packages need to be installed.

Vector Vs. Scalar Processors: a Performance Comparison Using a Set of Computational Science Benchmarks
Vector vs. Scalar Processors: A Performance Comparison Using a Set of Computational Science Benchmarks Mike Ashworth, Ian J. Bush and Martyn F. Guest, Computational Science & Engineering Department, CCLRC Daresbury Laboratory ABSTRACT: Despite a significant decline in their popularity in the last decade vector processors are still with us, and manufacturers such as Cray and NEC are bringing new products to market. We have carried out a performance comparison of three full-scale applications, the first, SBLI, a Direct Numerical Simulation code from Computational Fluid Dynamics, the second, DL_POLY, a molecular dynamics code and the third, POLCOMS, a coastal-ocean model. Comparing the performance of the Cray X1 vector system with two massively parallel (MPP) micro-processor-based systems we find three rather different results. The SBLI PCHAN benchmark performs excellently on the Cray X1 with no code modification, showing 100% vectorisation and significantly outperforming the MPP systems. The performance of DL_POLY was initially poor, but we were able to make significant improvements through a few simple optimisations. The POLCOMS code has been substantially restructured for cache-based MPP systems and now does not vectorise at all well on the Cray X1 leading to poor performance. We conclude that both vector and MPP systems can deliver high performance levels but that, depending on the algorithm, careful software design may be necessary if the same code is to achieve high performance on different architectures. KEYWORDS: vector processor, scalar processor, benchmarking, parallel computing, CFD, molecular dynamics, coastal ocean modelling All of the key computational science groups in the 1. Introduction UK made use of vector supercomputers during their halcyon days of the 1970s, 1980s and into the early 1990s Vector computers entered the scene at a very early [1]-[3]. -

Shared-Memory Vector Systems Compared
Shared-Memory Vector Systems Compared Robert Bell, CSIRO and Guy Robinson, Arctic Region Supercomputing Center ABSTRACT: The NEC SX-5 and the Cray SV1 are the only shared-memory vector computers currently being marketed. This compares with at least five models a few years ago (J90, T90, SX-4, Fujitsu and Hitachi), with IBM, Digital, Convex, CDC and others having fallen by the wayside in the early 1990s. In this presentation, some comparisons will be made between the architecture of the survivors, and some performance comparisons will be given on benchmark and applications codes, and in areas not usually presented in comparisons, e.g. file systems, network performance, gzip speeds, compilation speeds, scalability and tools and libraries. KEYWORDS: SX-5, SV1, shared-memory, vector systems averaged 95% on the larger node, and 92% on the smaller 1. Introduction node.
