All changes are from November 2000 to June 2001 :

ASCI White is #1 with an increased performance of 7.2 TF/s on the Linpack
Two new systems broke into the leading group of four ASCI systems from last year.
#2 is a new IBM SP system at NERSC/LBNL
#5 is a new Hitachi SR8000/MPP system at the University of Tokyo
Two more systems are new in the TOP10: - #8 a NEC SX5 installead at Osaka University, the first vector based system in the TOP500 - #10 a new IBM system at NCEP, which is an identical sister system to #9 at the same location
12 systems have Linpack performance above 1 TFlop/s
25 systems have peak performance above 1 TFlop/s including two IBM Netfinity clusters (#30 and #31)
1.18 Tflop/s is the entry point for the Top 10

132 systems fell of the end of the TOP500 since last June
Total accumulated performance is 108.8 TFlop/s compared to 88.1 TFlop/s 6 month ago
Entry level is now 67.8 GF/s compared to 55.1 GF/s 6 month ago
The entry point for the top100 moved from 181 GF/s to 241 GF/s.

The US keeps it's prime position as supercomputer user and producer with only little changes in geographical distribution
The number of machines used in industry decreased slightly to 236 from 245.
The number of machines used in research stayed stable at 118 (from 119).
The number of machines used in academic continues to recover to 92 from 86.
IBM is dominating the TOP500. It is leading the list with respect to the number of systems installed and the installed performance with a stable share of 40% and 42%.
Sun is second in the number of systems with 81 (16.2%) and fourth in performance with 8.6%.
With respect to installed performance Cray Inc. keeps the second position with 13.1% of performance. (fourth in systems 9% (45))
SGI is third with respect to systems with 63 systems (12.6%) (third in performance 10.2%)
All vector based systems are of Japanese origin.
