Overview of Recent Supercomputers
Overview of recent supercomputers Aad J. van der Steen HPC Research NCF L.J. Costerstraat 5 6827 AR Arnhem The Netherlands [email protected] www.hpcresearch.nl NCF/HPC Research October 2011 Abstract In this report we give an overview of high-performance computers which are currently available or will become available within a short time frame from vendors; no attempt is made to list all machines that are still in the development phase. The machines are described according to their macro-architectural class. The information about the machines is kept as compact as possible. No attempt is made to quote price information as this is often even more elusive than the performance of a system. In addition, some general information about high-performance computer architectures and the various processors and communication networks employed in these systems is given in order to better appreciate the systems information given in this report. This document reflects the technical momentary state of the supercomputer arena as accurately as possible. However, the author nor NCF take any responsibility for errors or mistakes in this document. We encourage anyone who has comments or remarks on the contents to inform us, so we can improve this report. NCF, the National Computing Facilities Foundation, supports and furthers the advancement of tech- nical and scientific research with and into advanced computing facilities and prepares for the Netherlands national supercomputing policy. Advanced computing facilities are multi-processor vectorcomputers, mas- sively parallel computing systems of various architectures and concepts and advanced networking facilities.

Introducing the Cray XMT
Introducing the Cray XMT Petr Konecny Cray Inc. 411 First Avenue South Seattle, Washington 98104 [email protected] May 5th 2007 Abstract Cray recently introduced the Cray XMT system, which builds on the parallel architecture of the Cray XT3 system and the multithreaded architecture of the Cray MTA systems with a Cray-designed multithreaded processor. This paper highlights not only the details of the architecture, but also the application areas it is best suited for. 1 Introduction past two decades the processor speeds have increased several orders of magnitude while memory speeds Cray XMT is the third generation multithreaded ar- increased only slightly.

Merrimac – High-Performance and Highly-Efficient Scientific Computing with Streams
MERRIMAC – HIGH-PERFORMANCE AND HIGHLY-EFFICIENT SCIENTIFIC COMPUTING WITH STREAMS A DISSERTATION SUBMITTED TO THE DEPARTMENT OF ELECTRICAL ENGINEERING AND THE COMMITTEE ON GRADUATE STUDIES OF STANFORD UNIVERSITY IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY Mattan Erez May 2007 c Copyright by Mattan Erez 2007 All Rights Reserved ii I certify that I have read this dissertation and that, in my opinion, it is fully adequate in scope and quality as a dissertation for the degree of Doctor of Philosophy. (William J. Dally) Principal Adviser I certify that I have read this dissertation and that, in my opinion, it is fully adequate in scope and quality as a dissertation for the degree of Doctor of Philosophy. (Patrick M. Hanrahan) I certify that I have read this dissertation and that, in my opinion, it is fully adequate in scope and quality as a dissertation for the degree of Doctor of Philosophy. (Mendel Rosenblum) Approved for the University Committee on Graduate Studies. iii iv Abstract Advances in VLSI technology have made the raw ingredients for computation plentiful. Large numbers of fast functional units and large amounts of memory and bandwidth can be made efficient in terms of chip area, cost, and energy, however, high-performance com- puters realize only a small fraction of VLSI’s potential. This dissertation describes the Merrimac streaming supercomputer architecture and system. Merrimac has an integrated view of the applications, software system, compiler, and architecture. We will show how this approach leads to over an order of magnitude gains in performance per unit cost, unit power, and unit floor-space for scientific applications when compared to common scien- tific computers designed around clusters of commodity general-purpose processors. -
