The following table 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:
If Rmax from Table 3 of the LINPACK Report is not available, we use the TPP performance given in Table 1 of the LINPACK Report for solving a system of 1000 equations. In a few cases we interpolated between two measured system sizes or we scaled by cycle times. For models where we did not receive the requested data, the performance of the next smaller system measured is used.
If there should be any changes in the performances given in the following table we will update them.
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.
In the following table, the computers are ordered first by their Rmax value. In the case of equal performances (Rmax value) for different computers, we have chosen to order by Rpeak. For sites that have the same computer, the order is by memory size and then alphabetically.
