The Top 500 list for June 2010 has been released.
Some of the higlights:
• A Chinese system called Nebulae, build from a Dawning TC3600 Blade system with Intel X5650 processors and NVidia Tesla C2050 GPUs is now the fastest in theoretical peak performance at 2.98 PFlop/s and No. 2 with a Linpack performance of 1.271 PFlop/s. This is the highest rank a Chinese system ever achieved. There are now 2 Chinese systems in the TOP10 and 24 in the TOP500 overall.
• China keeps increasing its number of systems to 24 and is now tied with Germany (steadily declining) for spot No. 4 after the USA, UK and France.
• China also climbed with respect to overall installed performance and is now holding for the first time the No. 2 spot behind the USA and ahead of Germany.
• The Jaguar system at Oak Ridge National Laboratory managed to hold the No. 1 spot with 1.75 PFlop/s Linpack performance even as it’s peak performance is lower than the Chinese Nebulae system.
• The most powerful system in Europe is an IBM BlueGene/P system at the German Forschungszentrum Juelich (FZJ) which dropped to No. 5.
• Intel dominates the high-end processor market 81.6 percent of all systems and over 90 percent of quad-core based systems.
• The Intel Core i7 (Nehalem-EP) processors increased their presence in the list with 186 systems compared with 95 in the last list.
• Quad-core processors are used in 85 percent of the systems and 5 percent use already processors with six or more cores.
• The Tianhe-1 system at No. 7, which is a hybrid design with Intel Xeon processors and AMD GPUs. The TH-1 uses AMD GPUs as accelerators. Each node consists of two AMD GPUs attached to two Intel Xeon processors.
• IBM regains the lead in market share by total systems from Hewlett-Packard, IBM also stays ahead by overall installed performance.
• The Cray’s XT system series remains very popular for big research customers with 10 systems in the TOP50 (20 percent).
Also, there is a nice chart that illustrates the evolution of the list:
