The 19th Top 500 Supercomputer list was released at the International 
Supercomputer Conference (ISC2002 in Heidelberg) this past June. Since 
the previous list came out 6 months prior, there've been quite a few 
changes in the supercomputing world, and the number one spot on the 
is now occupied by the Japanese Earth Simulator. Performance of 
on the Top 500 list is measured with the Linpack benchmark, which 
solving a system of linear equations. According to the Web site,

at Lawrence Livermore National Laboratory) by a factor of almost 5 in 
Linpack performance. You can find a detailed definition of the Linpack 
benchmark as well as the entire June 2002 Top 500 list at:
