Jack Dongarra has updated his report (in pdf) on supercomputers on October 28, 2003, and now the Apple G5 dual supercluster is third in the list of top 500 supercomputers. The R_max speed is now 9.6 teraflop/s, almost 20% improvement from the previous value last week. Apparently they are still tuning the communications network for getting maximum performance of the system. I wonder if the Infiniband network will be able to match the speed of the G5 processors. Here is a listing (updated October 28, 2003) of the top-5 systems from the draft report: Note that the Apple G5 dual result are not for the whole system of 2200 processors. All the speeds are in gigaflop/s (10^9 floating point operations per second).
