s39L来了，下载及说明见一楼：）
官方论坛上有个人算了比关于优化程序的帐：
Just a few quick observations on the economic impact of S39 and the contribution that Akos has made. From the current server stats:
Active hosts: 75,218
potential flops: 93.8
actual flops: 41.3
calculated number of hosts actively crunching for Einstein:
75,218*41.3/93.8 = 33,118
Power consumption per host approx. 300W+ [some are multi CPU, count fans, power supplies, hard drives, screens sometimes on]
10,000kW at US $ 0.20 per kW/h = $2,000 per hour / $48,000 per day
calculating all S4 results in approx 200 days: $9,600,000.00 total energy cost to the Einstein contributors.
calculating all S4 results in approx 50 days: $2,400,000.00 total energy cost to the Einstein contributors.
Savings $7,200,000.00 for S4 analysis.
So maybe it's just $5M ... or maybe I have a mistake in those calculations somewhere, whatever, it's huge!
