MacBidouille links to an interim update on Supercomputer rankings (pdf - Page 53).
The latest results give the Virginia Tech G5 Cluster (2,112 Processors) a score of 9.5 TFlops. Previous preliminary results placed the G5 Cluster at 7.41 TFlops which placed it at 4th place.
The new score of 9.5 TFlops overtakes a Linux 2,304 Processor Intel Xeon cluster from last year's list along with what appears to be some new entries this year (see PDF list).
Again, these are still preliminary numbers. Official numbers to be released in November.
