The IBM ASCI Blue-Pacic System is a scalable, distributed/shared memory architecture designed to reach multi-teraop performance. The IBM SP pieces together a large number of nodes, each having a modest number of processors. The system is designed to accommodate a mixed programming model and also supports a pure message-passing paradigm. We examine a number of applications on this architecture and evaluate their performance and scalability. 1 Introduction The IBM ASCI Blue-Pacic System is a scalable, distributed/shared memory architecture designed to reach multi-teraop performance. The system, which is located at Lawrence Livermore National Laboratory, is intended to meet the needs of the Accelerated Strategic Computing Initiative (ASCI) [1], whose purpose is to help ensure the safety and reliability of the US nuclear stockpile in the absence of testing. This presentation discusses the performance and impact of a three-dimensional hydrodynamics code, along with several other ...
