"Announced earlier today, the 35th list of the top 500
supercomputers contains few surprises, just that Linux has almost
total domination of the list.
"Just as with the previous list of the Top500 Supercomputers,
the Oak Ridge National Laboratory's Cray XT5 'Jaguar' leads the
pack with a sustained performance of 1.76 PFlop/s. However, a new
Chinese entrant called Nebulae has achieved a higher peak
performance of 2.98 PFlop/s (compared to Jaguar's peak of 2.33
PFlop/s) and is placed second overall.
"Of the 187 new entrants, all but one are running some variant
of Linux and in fact 470 of the Top 500 run Linux, 25 some other
Unix (mostly AIX) and the remaining 5 run Windows HPC 2008."
