[edit] TOP 25 Supercomputer Sites of All Times

The following table shows the TOP25 Supercomputing Site since the list has started back in 1993.The ranking is determined using the sum of the Rmax share of every site in every list since 1993.

For example:

Total Rmax in 1993 was 1.12 TFlops and Los Alamos National Laboratory had a total of 7 systems with a combined Rmax of 86.34 GFlops, thus, the share of LANL for June 1993 would be approx. 0.077. We then add those shares per site and rank the sites using the sum of the shares.
