Since last November, another five spots on this biennial list are taken by systems based on HP server blades.   On the latest list, I count  206 of the 500 fastest computer systems in the world -- over 41% -- as being powered by HP BladeSystem.

  Some of the highlights really show how far high performance systems have come -- and how quickly they change:

• Quad-Core processors are used in about 75% of the systems.  Only 4 systems still use single-core processors.
• The total combined performance of all 500 systems has grown 33% from just 6 months ago.
• The slowest system on this June, 2009 list would have placed right in the middle -- number 274 -- of last November's list.
