外国高手回信了！关于ap任务获取的问题，原来是这样！！
本帖最后由 tongyang7799 于 2013-10-17 00:49 编辑抱着试试看的心态给国外一个算友发了个私信，没想到居然回复了好长一篇文章！
这是我发送的：
你好~我是你来自中国的朋友，很高兴认识你，我的英语不好，还请原谅。我想请教你个问题：我的电脑和你的电脑性能相似，是3770K的cpu，titan的显卡，但是为什么每天平均分只有20000呢？是不是计算 AstroPulse v6 GPU才能提高我的分数呢？但是我发现 AstroPulse v6 GPU很难获取到任务，怎么才能获取到呢？请您教一下我，非常感谢！
Hello ~ I'm your friend from China, nice to meet you, my English is not good, please forgive me. I would like to ask you a question: my computer and your computer performance is similar to that of 3770K cpu, titan graphics, but why do the daily average of only 20,000? Is not AstroPulse v6 GPU computing in order to improve my score it? But I found difficult to obtain AstroPulse v6 GPU to the task, how to get to it? Please teach about me, thank you very much!
外国朋友回复的：Hello, Emma, I am very pleased to meet you and hope that we can be good friends! Your English is very good. I speak no Chinese at all, so it is I that must apologize to you.
You are correct that it is very difficult to obtain AP work units because there are much fewer of them, and everybody wants to have them.
You can set your S@H preferences on the BOINC site to:
Run only the selected applications SETI@home Enhanced: no
SETI@home v7: no
AstroPulse v6: yes
If no work for selected applications is available, accept work from other applications? yes
That way, AP's will have some priority over MB's, but you would still not be able to reach the maximum 100 AP's in your queue because BOINC will still be sending you MB's as well.
Are you familiar with the Server Status Page(SSL) at http://setiathome.berkeley.edu/sah_status.html ? If you look at the data under the Splitter Status Heading, the "total channels to do" for AP is 0, meaning that there are no AP's available right now. Also, you can see that there are approximately 200 Multibeams(MB) available. When the MB number comes down to approx. 100 or less, they will need to make more wu's available to keep the queues filled. That is when more AP's will be available. At that point, I change my settings to allow ONLY AP's to download - no more MB's. Since I still have MB's on my disk, I continue to process those wu's, while AP's slowly start to backfill my queue. It takes at least 24 hours for my queue to fill because BOINC only sends a few AP's at a time. When the AP "total channels to do" goes down to 0 (which usually takes only 3 or 4 days), I reset my preferences back to accept both AP's and MB's.
Getting the correct timing on this is critical for obtaining the maximum AP's - you would need to experiment to find what works best in your time zone and your personal schedule.
But I'm wondering about the errors in your results - have you solved the problem there? Also, it looks like you may not have all the settings tweaked in your app.info file to maximize your Titan, and also looks like you may only be processing one file at a time? I don't want to intrude on the way you prefer to run and I may be wrong about your settings - I just want to mention this in case you were not aware?
PS：外国朋友好热情啊！！真是受宠若惊~~有谁能精确的翻译下不？
按照如下设置你的SETI@Home参数：
Run only the selected applications SETI@home Enhanced: no
SETI@home v7: no
AstroPulse v6: yes
If no work for selected applications is available, accept work from other applications? yes
这样的话，AP会相比MB有更高的权限。但是你依然很难在队列中达到100个AP的上限，因为无论如何系统都会给你发放MB
你可以看这个地址： http://setiathome.berkeley.edu/sah_status.html
现在没有AP包，不过有200个左右的MB。当MB包的数量低于100个左右的时候，系统会生成更多的任务，那个时候就有AP可以发放了。同时，我更改设置，只接受AP包。因此，我的设备在计算MB包的同时，也在慢慢的补充新的AP包。通常这需要1天的时间，因为系统每次只发放少量的AP包。而当所有的AP包发放完毕之后（通常只有3-4天），我再把设置调回到同时接受AP和MB包。
另外，你似乎没有让你的titan满载，而且好像没有同时计算多个任务。他建议你查看一下你的设置。
简单的说就是：没有AP包的时候同时接受AP和MB确保有任务算，有AP包之后立马改成只接受AP包。而且似乎他是同时计算多个WU的。 Stella 发表于 2013-10-17 00:34

恩~我看现在的ap任务是0了~怪不得收不到任务呢~等再发放的时候试试看！

他说这是他的方法，他建议你根据自己的时差试试看，找一个最佳的实际操作方法。
另外，你看看你的设置问题，然后给他回个信吧
麻烦，多电脑会崩溃的，还是最简单只接受ap外加没任务时接受其他，基本没时间去看，自动算好了。 其实吧……算算einstein也好~
不过总觉的titan跑这些东西有点儿浪费…… Stella 发表于 2013-10-17 00:57

来跑GPUGRID吧=w=
TITAN平均一天能跑400,000以上~

至少100多万

老外还说了你的结果中有错误，问你有没有解决。
检查一下吧，要不然算了半天因为错误没得到分多可惜啊

这么多分
7850能得多少啊？
tongyang7799 发表于 2013-10-17 00:51
哇哦！英语达人啊！多谢多谢！终于搞明白怎么回事了！~~
我的方法是先囤积些MB 然后只接受AP 等待系统自动下载如果MB没了再囤积一些 ，过几天吧7750也跑起来
虽然性能低点但是可以7*24
