In the latest ranking of the top 500 supercomuters AMD's Opteron processor increased its presence. Intel's Itanium continued to fall and IBM took top honors among vendors.
The latest list was expected to be unveiled at the International Supercomputing Conference in Germany on Wednesday. The Top 500 project measures the world's fastest supercomputers according to the Linpack benchmark, which focuses on solving linear equations.
Servers based on x86 processors from Intel and AMD have been taking over the list in recent years. Intel's processors can be found in 301 of the Top 500 systems, with its 64-bit Xeon processors accounting for 118 of those systems. However, that's down from 333 in November, the last time the list was released. AMD's Opteron processors now can be found in 81 of the servers, up dramatically from 25 systems last year and 55 systems in November. Intel's Itanium processor continued its descent down the list, now accounting for just 37 systems compared with 46 in November and 79 a year ago.
