Top Super Stats

From the June 2010 list, Top-Supercomputers India is collecting additional statistics, Top Super Stats, about the supercomputers besides the Linpack benchmark performance. The objective of Top Super Stats is to enable comparison of supercomputers and installations regarding the usage of the systems, kind of applications, and application performance. Using this stats that will be uploaded in the web page, the installations can make informed decisions about procurements highly tuned to their needs. This will also enable the supercomputer vendors to tune their systems for better application performance for various applications.
