The TOP500 List

Table 2.1 shows the 500 most powerful commercially available computer systems known to us. To keep the list as compact as possible, we show only a part of our information here: [tex2html_wrap3854]Position within the TOP500 ranking Manufacturer Manufacturer or vendor Computer Type indicated by manufacturer or vendor Installation Site Customer Location Location and country Year Year of installation/last major update Field of Application #Proc. Number of processors [tex2html_wrap3856] Maximal LINPACK performance achieved [tex2html_wrap3858] Theoretical peak performance [tex2html_wrap3860] Problemsize for achieving [tex2html_wrap3862] [tex2html_wrap3864] Problemsize for achieving half of [tex2html_wrap3866]

If [tex2html_wrap3868] from Table 3 of the LINPACK Report [7] is not available, we use the TPP performance given in Table 1 of [7] for solving a system of 1000 equations. In a few cases we interpolated between two measured system sizes or we scaled by cycle times. ``A table with the used performances can be found in chapter 3 of this volume.''For models where we did not receive the requested data (e.g., Hitachi S3800/480, KSR1-256, bigger models of Paragon XPS), the performance of the next smaller system measured is used.

In Table 2.1, the computers are ordered first by their [tex2html_wrap3870] value. In the case of equal performances ([tex2html_wrap3872] value) for different computers, we have chosen to order by [tex2html_wrap3874]. For sites that have the same computer, the order is alphabetically.
