All system reported have to be installed by October 30, 2000.
The List's maintainers are interested in new entries as well as entries
that are no longer valid. Following is a transcript of the guidelines for
submission of entries.
To provide a better basis for statistics on high-performance computers, we
list twice a year the sites that have the 500 most powerful computer systems
installed. The best Linpack benchmark performance achieved is used as a
performance measure in ranking the computers.
Submissions
Companies or individuals may submit entries for inclusion to us.
Submissions should contain the following information:
Manufacturer: Manufacturer or vendor
Computer system: Type indicated by manufacturer or vendor
Installation Site: Customer - Full name of company or institution
Location: Location and country
Year : Year of installation/last major update
Field of Application: type of customer (university, government, industry,
...) as well as typical application (geophysics,
automotive, chemical, benchmarking, ...)
Processors: Number of processors (as well as type if necessary)
Memory : Main memory configuration of the system
inpack performance
Performance numbers for the Linpack benchmark are collected and updated by
Jack Dongarra (dongarra@cs.utk.edu). Please report any Linpack performance
numbers directly to him.
Method of Solution
In an attempt to obtain uniformity across all computers in performance
reporting, the algorithm used in solving the system of equations in the
benchmark procedure must confirm to the standard operation count for LU
factorization with partial pivoting. In particular, the operation count for
the algorithm must be 2/3 n^3 + O(n^2) floating point operations. This
excludes the use of a fast matrix multiply algorithm like "Strassian's
Method". This is done to provide a comparable set of performance numbers
across all computers.
Verification
In addition to cross checking different sources of information, we select
randomly a statistical representative sample of the first 500 systems of our
database. For these systems we ask the supplier of the information to
establish direct contact between the installation site and us to verify the
given information. This gives us basic information about the quality of the
list in total.
Restrictions
As the TOP500 should provide a basis for statistics on the market of
high-performance computers, we limit the number of systems installed at
vendor sites. This is done for each vendor separately by limiting the
accumulated performance of systems at vendor sites to a maximum of 5 percent
of the total accumulated installed performance of this vendor. Rounding is
done in favor of the vendor in question.
