Each year the first TOP500 list is released in June at the International Supercomputer Conference, in Hamburg, Germany.
The List's maintainers are interested in new entries as well as entries that are no longer valid. Please feel free to contact them here if you have questions.
Following is a transcript of the guidelines for submission of entries:
The deadline for the submission of new sites for the November release of the TOP500 List is October 25th (23:59 PST). All system reported have to be installed by November 1st. The last date for submitting linkpack updates is also November 1st ( Systems must have been submitted by the deadline above).
Submission deadline for the June release of the TOP500 List is May 18th (23:59 PST). All system reported have to be installed by June 1st. The last date for submitting linkpack updates is also June 1st. (Systems must have been submitted by the deadline above)
The submissions site is now open. Please visit http://top500.org/submit. You might need to create a new account to be able to submit systems.
Please note that this is a completely new interface and you have to create a new login and password.
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
Performance numbers for the Linpack benchmark are collected and updated by Jack Dongarra (firstname.lastname@example.org). 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 LU factorization with partial pivoting. In particular, the operation count for the algorithm must be 2/3 n^3 + O(n^2) double point floating point operations. This excludes the use of a fast matrix multiply algorithm like ``Strassen's Method'' or algorithms which compute a solution in a precision lower than full precision (64 bit floating point arithmetic) and refine the solution using an iterative approach. This is done to provide a comparable set of performance numbers across all computers. You can obtain an implementation of the appropriate software at: http://www.netlib.org/benchmark/hpl/
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.
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.
The main objective of the TOP500 list is to provide a ranked list of general purpose systems that are in common use for high end applications. The authors of the Top500 reserve the right to independently verify submitted LINPACK results, and exclude systems from the list which are not valid ornot general purpose in nature. By general purpose system we mean that the computer system must be able tobe used to solve a range of scientific problems. Any system designed specifically to solve the LINPACK benchmark problem or have as its major purpose the goal of a high Top500 ranking will be disqualified.
The systems in the Top500 list are expected to be persistent and available for use for an extended period of time. Any system assembled to run a LINPACK benchmark only, and set up specifically to gain an entry in the Top500 will be excluded from the list. The TOP500 authors will reserve the right to deny inclusion in the list if it is suspected that the system violates these conditions.
