The Top 500 SuperComputers Sites has released the list of world’s TOP500 supercomputers. Linux computers have again topped the list. The top spot was grabbed by 1.105 petaflop/s IBM supercomputer. Some of the highlights of the report are as follows:
-
A total of 379 systems (75.8 percent) are now using Intel processors. This is virtually unchanged from six months ago (375 systems, 75 percent). Intel continues to provide the processors for the largest share of TOP500 systems.
-
The IBM Power processors and the AMD Opteron family are almost tied as second most common processor family with 60 and 59 systems each (12 percent and 11.8 percent). Both had only minor changes from six months ago.
-
Quad-core processor based systems have taken over the TOP500 quite rapidly. Already 336 systems are using them. 153 systems are using dual-core processors, and only four systems still use single core processors. Already seven systems use IBMs advanced Sony PlayStation 3 processor with nine cores.
-
HP took over the lead in systems with 209 systems (41.8 percent) over IBM with 188 systems (37.6 percent). IBM had 210 systems (42.0 percent) six months ago, compared to HP with 183 systems (36.6 percent). But IBM still stays ahead by overall installed performance.
