The Top 500 have published their results. The CHPC appears once again -> http://www.top500.org/site/history/3006
The following table shows previous lists and the number of systems installed when the list was published. Site Efficiency in the table is SUM(Rmax)/SUM(Rpeak), expressed as a percentage.
| List | Systems | Highest Ranking | Rmax(GFlops) | Rpeak(GFlops) Site Efficiency(%) | |
| 11/2009 | 1 | 311 | 25440.00 | 30860.80 | 82.43 |
| 11/2008 | 1 | 128 | 23415.00 | 27850.00 | 84.08 |
This is the Tsessebe SunBlade X6275 and X6250, Xeon X5570 and E5450 with Infiniband QDR/DDR
| Procs | Memory(GB) | Rmax (GFlops) | Rpeak (GFlops) | Vendor |

Our 16 core Tyan (GB Eth + 512 GB + Win HPC) does 43.7490 GFlop - that is 2.73 GFlop/core compared to 9.7 GFlop / core. We have 68.6% efficiency - I think it is due to the network being pedestrian.
OK CHPC you win on performance, but I bet we beat you on cost per GFlop and number of customers per GFlop :)
I guess that the CHPC will be out of the Top 500 in June.
