SETI/BOINC Milestones [ v2.0 ] - XXV
(Message 1362248)
Posted 22 days ago by Link
A milestone for my AthlonXP 2000+ machine: 200,000 SETI@Home credits. That's since August 2009, some of the credits of my other no longer active AthlonXP system were actually done on this hardware when it was my desktop system and also almost all my classic WUs. |

Always exclude the entire BOINC data directory from scanning, that keeps all problems regarding AV away. |

Laptop too hot?
(Message 1355466)
Posted 40 days ago by Link
I found using spacers at the feet of the notebook to have a larger air gap under the unit on a hard surface did a great job of helping cool it. Much more so than one of those "notebook coolers". Yes, spacers are the best. I tried one of those notebook coolers and compared with simple spacers I had 2°C more (!) on the CPU (with or without the fans turned on, didn't matter, they were useless) and lots of noice if the fans were on. The Pentium M I have is running at 55°C with the fan running on the lowest setting, but that's after undervolting by about 300mV, some case modifications and standing on spacers. In summer I take off the cover under it, but that can be done only on laptops, that are used only on one place. |

Rejecting/Avoiding VLAR on an Intel i486 DX4-S/100?

and remember that the whole project was launched, with the first standalone 'classic' applications, after Windows 98. And IIRC they were all 32-bit Windows applications, also the CLI version. |

Yes, memory managers like Memmaker shunted aside a bunch of stuff to make a bigger memory space... That was exactly what you needed to do if all you were going to use the machine for the next few hours for was gaming. My memory is telling me that Memmaker actually used a boot floppy with a dedicated, purpose built .ini file that didn't even load anything that wasn't required for the intended application to run. Perhaps later versions of Memmaker did move things to swap from within a running Windows OS, I will not challenge you in that, just raise a mental eyebrow and wonder if we're talking about the same software. It doesn't matter in the end though. As you have written in your later post, all of that applies to DOS and all those stuff became pretty much unnecessary when Windows came out. I switched to Windows 95 with my 486, tried few of those memory managers, all I noticed was slow down on restoring applications from task bar and additional RAM usage by the memory manager itself, which was quite a lot considering I had just 8MB RAM in that machine. So after some experiments I found, that leaving Windows alone with RAM management was the best thing to do. So putting a bunch of Stuff that the OS doesn't need into swap file where it will never be accessed, exactly as you say, seems to be a win/win situation. And Windows will do that as soon as something actually needs that RAM, just like it does, when the memory manager requests RAM. Windows 98 might not do that as good as current versions do, but it does not need any help from other programs to do it. |

Also, on Windows 98, if I recall correctly, there were still effective memory manager programs designed to clean up the way that Windows allocated memory in order to allow high RAM usage applications to run faster. All those (completely useless btw.) programs did, was requesting large amount of RAM, so that other programs were swaped out to the pagefile and had to be put back to RAM as soon as you needed them again. Yeah, that sounds very useful and effective... |

Windows TCP Settings - Follow up - Help with server communication
(Message 1354475)
Posted 43 days ago by Link
Has anyone tried disabling TCP fix after relocation of servers? There's no need to do it, the "fix" just makes Windows use features, which Linux is using by default. Also it does not only help with connection to SETI servers, but all overloaded servers/connections. For me for example it also helped in case of Rosetta, where I was also getting HTTP errors every now and than, depending on the load on their servers. And it disabled backoffs on my BOINC 6.12.34 machine, however that is possible, so no, that will stay here as it is. |

Is that what we see here some sort of software 100Mbit cap, that does not work properly yet, or does that only look like that? But untill now downloads are working perfectly... so maybe it only looks like that. |

I think it may be better to buy a used gamming PC for 200$ and do 10x to 50x more. But an old gaming PC will very likely use more than just 10-50x more energy. |

MW also runs CreditNew - they certainly tend to run latest server version (with all the problems that entails). They only use CreditNew for nBody WUs, separation WUs have fixed Credit depending on how many stars are used. On x86 CPUs they pay only a bit better than SETI stock apps. |

A follow on question: Well, in my case of BOINC 6.12.34 it helps for sure, since I applied the fix BOINC decided not to use any backoffs at all, at least not for fole transfers. Looking like that in my log: 22/03/2013 22:47:55 rosetta@home Started download of rb_03_12_36962_70171_h002__synp_aah002_07_05.200_v1_3.gz A 0-2 second backoff is OK to me. |

Haunted by SETI Past, How to Delete a Rogue Machine?
(Message 1347381)
Posted 65 days ago by Link
Once you've returned a result you should just sit back and wait. If your result is validated you will get the credit, if it isn't you won't. Just remember S@H is already looking at data that has taken years to get to us, and many cases that recording of that data is about a year old. (+) The idea of selecting your wingmen, either by name or by pool, has been discussed many times before. The reason its not allowed is historic, but its basis is to reduce the possibility of folks fiddling their results to enhance the credit awarded. That's the small issue. Sending back fake results without actually crunching the WU would be a lot worse for the project. |

BTW, most of the inconclusives have nothing to do with the "dettached" or no longer active hosts, Most? All. Inconclusives have been returned by the wingmen, but the results are not similar enough. WUs, that have no longer active hosts as wingmen are "Completed, waiting for validation". |

Ha ha, I was just trying to save some people a wait. If that is a bad thing, excuse me. It's not a bad thing, but not worth the efford at all. There are thousands of WUs, that will never be returned, your 57 does not change anything. The system is build to handle things like this by itself. Actually, considering the current bandwidth issues, letting the WUs time out is the best you can do, as that does not generate additional load on SETI's internet connection. |

Windows TCP Settings - Follow up - Help with server communication
(Message 1346898)
Posted 66 days ago by Link
OK, so now I rebooted all my machines after the Microsoft patch day... here a little summary of what I've got: 1. My old AthlonXP, currently the only machine crunching SETI, is still getting about 3 http errors per WU. Can't say if it would be more without the registry fix. Well, nevermind, it needs just 2-6 WUs per day. 2. My laptop: nothing special, had no real issues before and does not have any now. 3. My desktop: that's the interesting one and the actual reason why I post this. It's running also Rosetta right now, and they are apparently running also into some issues with server/bandwidth load as has been reported by many people over there. Anyway, the TCP fix improved communication with Rosetta servers quite notably, even the message boards open a lot better, i.e. without some small breaks when loading (sometimes it would even stop loading before I applied the fix). Using a proxy was fixing all Rosetta related issues for me same as it did for SETI downloads, except for it was causing issues with uploads, which were working perfectly without a proxy. Now comes the interesting part: as soon as I added the dword to the registry BOINC stopped using any backoffs, i.e. if it got http error, it would retry the download instantly after that. No waiting at all. And only on this machine (Win7, BOINC 6.12.34), the other two (WinXP, BOINC 6.10.18) have normal backoffs like before including also the usuall messages in the log (backing of download of...). Here nothing, just instant retry. I mean, I don't want to complain about getting rid of those 6.12-backoffs, but has anybody else noticed that? Or is it just me? EDIT: downloaded one SETI WU on the Win7 machine, actually to check wether it will still not use any backoffs, but of course I didn't get any http error when I wanted one. It was downloading slow but "nice", i.e. at quite constant speed without any breaks or slow downs. That makes me ask one question: is it possible to check wether Windows is actually using the TCP fix? I mean actually check it, not just look into the registry? Because my AthlonXP host is still behaving like it did before while here there's clear difference. |

(Message 1346241)

Good one, that fixed it. Now it would be interesting to know, why BOINC is doing such stupid things on different platforms and also different BOINC versions... Seems to be a bug or something. My "permanent fix" for this is btw. increasing the max. file size for stdoutdae.txt to 10MB and a script, which deletes the file on shutdown. You also have some of those in your Astropulse tasks, but no idea what that means: <core_client_version>7.0.28</core_client_version> <![CDATA[ <message> process got signal 11 </message> <stderr_txt> </stderr_txt> ]]> |

Is there a way to use the proxy in boinc for download only ? And if you still want to use proxy, add the following in the "Don't use proxy for" box: setiboinc.ssl.berkeley.edu,setiboincdata.ssl.berkeley.edu + URLs to servers of whatever other projects you run. |
