Supercomputing Freakonomics - Finding Meaning Beyond the Headlines
,----[ Quote ]
| Twice a year, the Top500 Project publishes
| its list of the fastest supercomputers in the
| world. In the last announcement, we continue to
| see Linux dominating the list. This is nothing
| new since Linux has been dominating since the mid-2000s.
| In fact, Linux share in supercomputing looks a lot like
| Microsoftâs historical share of the desktop market. I
| thought it would be interesting to take a step back and
| look at the performance capability of these computers as
| a whole and also how the rise of Linux is mirroring the
| geographical expansion of supercomputers.
|
| Everybody tends to watch the number of Linux systems
| on the top500, but thereâs a fascinating story being
| told by the Rmax performance numbers (Rmax is the
| maximum performance of a computer (measured in Gflop/s)
| achieved in the HPL benchmark. In many ways, this is a
| much more enlightening statistic, because it shows
| us the overall nature of performance on this list,
| instead of just focusing on individual computers.
| (This time around, five Linux systems were actually
| bumped off the bottom of the list, even though Linuxâs
| *total* computing power grew by 38%.)
