S5R5 的一些消息

Any news about the S5R5 run mentioned earlier in this thread?? it was supposed to begin soon, because of some kind of bug on the results of the S5R4...

Will definitely come. We're still testing and tweaking the setup. Some facts so far:
- slightly increased memory requirement
- larger "dwell time" per sky location. This is limiting the maximum checkpoint rate to about once per 3 min (on current average CPUs, longer on slower ones)
- workunits will run roughly half as long as S5R4 ones

BM

内存要求有所增加，计算时间大概是s5r4的一半。

Can we use the current (605) power app, or will we need a new app/app_info

The S5R5 Windows App will feature the code that makes the S5R4 6.05 App as fast as it is.

There is no change in crediting targeted for S5R5.

计算程序将和s5r4的6.05版优化程序差不多，积分方面也不会有变化。

Also, the S5R5 run will work on the existing S5R4 datafiles, so the transition form S5R4 to S5R5 should be much smoother than the previous one from S5R3 to S5R4 where it was not possible to re-use downloaded datafiles from the previous run.

数据文件和s5r4相同。

如果在s5r4使用了6.05版优化程序（比如我自己。。。），到时候比较好的方法是设置成不下载新任务，算好现有的任务并上传上报，再删除app_info.xml并重启boinc。

那是什么时候出来啊？

(S5R5)绝对会到来的。我们仍在测试和微调安装程序，目前已确定的事实：
- slightly increased memory requirement
对内存的要求会略微增加
- larger "dwell time" per sky location. This is limiting the maximum checkpoint rate to about once per 3 min (on current average CPUs, longer on slower ones)
每个天区更长的“驻留时间”。这限制了存盘点的最大速率为3分钟每次（平均来讲，如果在比较慢的机器上，时间会更长些）
- workunits will run roughly half as long as S5R4 ones
WU的计算时间大概是S5R4的一半。

The S5R5 Windows App will feature the code that makes the S5R4 6.05 App as fast as it is.

//这两句楼主已翻，我就不赘述了。

Also, the S5R5 run will work on the existing S5R4 datafiles, so the transition form S5R4 to S5R5 should be much smoother than the previous one from S5R3 to S5R4 where it was not possible to re-use downloaded datafiles from the previous run.
而且，S5R5可以计算S5R4的数据文件，故而从S5R4升级到S5R5会比之前从S5R3升级到S5R4更平滑，因为S5R4无法计算S5R3的数据文件。//也就是说你有S5R4的屯粮的话，也不用等全部用S5R4程序计算完提交后，再去升级S5R5

再会

正在算的当然得算完最好，不过你的屯粮，表担心，看他的说法，S5R5可以计算那些屯粮。

Youth

和屯粮完全没有关系。。。另外，checkpoint译成存盘点应该好懂些。

那段话只是说任务包依赖的数据文件是相通的，就是类似于l1_0722.80_S5R4这些。

多谢Youth，我就在纳闷儿了，checkpoint在这里代表什么意思，这玩意儿随上下文变化很厉害的。

又将翻开新的一页....

Hi Gary!

Yes, with a bit of luck (i.e. if we don't find a problem in the very last minute) we'll start S5R5 around the weekend. We were just waiting for a green light that we got last night.

这周末s5r5就要开始了~终于。。。

Due to some remaining uncertainties we will restrict the frequency range of S5R5 to 1000Hz and then take a look at the results to decide whether we should push it up to the 1250Hz of the current S5R4. This reduces the projected total runtime of (the possibly first part of) S5R5 to about 6 months. We are working on some hoefully even more sensitive and efficient analysis methods (improving the "Hough transform"). If a new program is ready to be used by then, we'll also not extend S5R5, but start an S5R6.

由于一些非确定性的原因，s5r5的频率范围将限制在1000hz以下，根据其结果决定是否要上升到s5r4的1260hz。这样的话s5r5的持续时间将是6个月左右。我们也在试验一些更灵敏更有效的分析方法，如果有新的程序要使用，s5r5也不会延长，而是从s5r6开始。

The only consequence of this decision right now is that clients currently running S5R4 workunits above 1000Hz will need to get a new set of data files, while the others will just get S5R5 work for the data files they already have.

如果用户当前正在算1000hz以上的s5r4任务，到时将会自动下载一些新的数据文件，其它用户将仍可以继续使用本地已有的数据文件。

We'll stop the S5R4 workunit generator, but the workunits generated so far will be finished and credited. I'm not sure that pushing the last ones through is necessary, so I probably won't put time into this.

s5r4的任务将停止生成，已生成的任务将继续完成并授予积分。

There is no (intentional) change in the crediting, so wrt the credit it shouldn't matter whether you run S5R4 or S5R5 workunits. The S5R5 ones will run a bit shorter (design goal was 50%, but I'm afraid with the adjustments we had to make afterwards we missed it by about 10%).


新阶段的任务在得分方面保持不变，但任务的计算时间将减少。

刚发现计算程序升级到了6.10.不过还是S5R4的任务包.

Youth

看来6.10版优化测试结束正式发布了：）

我还是6.05

If the currents S5R4 are 40h for you, S5R5 should be 20h on average.

We're running some final tests, S5R5 should start today or tomorrow if we don't find any oddities.

各位大大 S5R5己正式開跑了 請多多注意喔!!

Youth

嗯，服务器状态页面已经更新了，但我这边还有些s5r4的包没算完
