Cray Research and Cray computers FAQ Part 5


This Cray supercomputer Faq is split into sections, Part 1 describes Cray supercomputer families, Part 2 is titled "Tales from the crypto and other bar stories", part 3 is "FAQ kind of items", part 4 is titled "Buying a previously owned machine" and part 5 is "Cray machine specifications". Corrections, contributions and replacement paragraphs to CrayFaq0220@SpikyNorman.net. Please see copyright and other notes at the end of each document.

Introduction

This section of the FAQ contains the specifications of various Cray supercomputers. Most of these specifications are drawn from published marketing materials and so may or may not exist as actual machines. Given the some what custom built nature of Cray supercomputers it's likely that some machines do not exactly fit these specifications. Listed in approximate date order. Linpack and other benchmark performance numbers can be seen at the Network performance database.
