CALL FOR PARTICIPATION
November'96 VERSION of
TOP500 SUPERCOMPUTER LIST
To provide a better basis for statistics on high-performance
computers, we have put together the
Top500 Supercomputer List. The
list is a collection of the sites that have the 500 most powerful
computer systems installed.
The next release of our Top500 Supercomputer List will be presented at
Supercomputing '96,
November 17-22 in Pittsburgh, PA.
We are interested in ``NEW ENTRIES'', as well as entries
that are no longer valid, on the Top500 List.
Please feel free to contact us at
top500@rz.uni-mannheim.de
if you have questions.
Thank you for your participation and your cooperation.

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 informations:
- 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
Linpack 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% of the total accumulated installed performance of this
vendor. Rounding is done in favor of the vendor in question.
