Windows :
Client wants to connect to localhost
(Message 205127)
Posted 6 Dec 2005 by Professor Ray Post: SO the problem remains: when you launch BOINC Manager, the window opens up, in the lower right it say "connecting to localhost" and you're dead in the water. That issue is internal on the host and has to be resolved before any DNS/DHCP issues. When you right click the B in the system tray, how are the run and network properties displayed? On the affected Win98 machine I'm gathering you can ping 127.0.0.1 without issue. Just grasping here: do you have a C:\\Windows\\HOSTS file? If so, open it with Notepad and verify that the first entry says 127.0.0.1 localhost. If you do NOT have a HOSTS file, then copy HOSTS.SAM to HOSTS. If you DO have a HOSTS, but 127.0.0.1 isn't the first entry, then make that so, save it (it'll warn you about text only formatting - that is o.k.), and rename it by truncating the TXT extension (allow the existing HOSTS file to be overwriten). Reboot. Let us know how you get on with that. The paramount thing needing to be established is a "connected to localhost" between the manager and the daemon. THAT is a fundamental aspect pertaining to interprocess communication of Windows itself. |

Number crunching :
Optimized BOINC 5.2.13 for Windows
(Message 204980)
Posted 6 Dec 2005 by Professor Ray Post: From the Wiki: Unified accounting means that all of the projects that will run on the BOINC System are going to calculate Cobblestones using the same rules and you will get your allocation of Credit using the same rules for work effort contributed to all Projects. My unoptimized BOINC client garners the following results: 938 (Whet), 1645 (Dhry). and the optimized BOINC v5.2.13 garners the following: 1071 (Whet), 2743 (Dhry) SciSoft Sandra 2001 garners these results: 1442 (Whet), 2958 (Dhry) this in comparison to a reference PIII1000 of: 1336 (Whet), 2920 (Dhry) and compared to a Duron 600: 1675 (Whet), 817 (Dhry). In all actuality the above stats are immaterial, in that despite the unknown performance of the reference machine with respect to SciSoft Sandra, ALL MACHINES ARE COMPARED AGAINST IT. From the forgoing we see that that credit conferred is based not on an average (or arithmetic mean) of claimed credit, but the median (the middle value of an odd numbered set, or the arithmetic mean of the two middle values if the set has an even numbered population) of that claimed. The credit claimed is determined arithmetically from CPU benchmarks. The median will be lower if the quorum is comprised of a greater number of low-end CPU's or un-optimized clients. Succinctly put: the credit granted is graded on a population weighted curve. Finally, the credit issue notwithstanding, CPU benchmarks appear critical for proper operation of the scheduler. In conclusion, I've decided that I'm going to forego use of the optimized BOINC client, in order to remain as fair as possible to all the other participants of non-SETI projects I'm engaged in. I'll be satisfied knowing that despite garnering less credit per unit SETI WU with my optimized SETI application, I'll be processing more SETI WU's per unit time (the net result will be more credit for SETI over time). |

Posted 6 Dec 2005 by Professor Ray Post: You on a dial-up or sumpin, Dude? When you get SETI going, resume Einstein, and then you're going to have to stay connected for a while. When you see that Einstein has begun downloading stuff in the messages panel, click the "transfers" tab. This will show you everything that's coming down the pipe (even stuff that's not in the pipe yet). EVERYTHING has to come down before you disconect. You might want to consider editing you're eAddy's there, and replace the "@'s" in 'em with "<AT>" or sumpin. Automated web-crawlers love that kind of stuff for spam you know.

Proposal for workunit caching
(Message 204532)
Posted 6 Dec 2005 by Professor Ray Post: The most expensive thing are requests for new work and reports of work done. Every time a BOINC client connects to project scheduller, a new process has to be started on server. That process then does some DB accesses etc. Handling multiple WUs (either assigning new work or receiving reports about finished work) here helps really a lot. This is achieved through delayed reporting, which would ideally mean that BOINC client would report say 5 results and request 5 new WUs with one single connection. Yeah, what you said, I second that. So if "connect every" is two days, then every two days it uploads whatever WU's it has, and downloads the difference between what WU's are on hand to crunch and 4 days anticipated processing (minus some fudge factor based on total-on time). |

(Message 204517)
Posted 6 Dec 2005 by Professor Ray Post: If I update the Boinc client it recognizes the change and asks me if I am aware of it, and gives me the option of allowing it or blocking it. Only those programs which are allowed can communicate. Plain vanilla but effective. Roger that. Works good. Lasts a long time. |

Optimized BOINC 5.2.13 for Windows
(Message 204510)
Posted 6 Dec 2005 by Professor Ray Post: My PIII1000 slot 1 just benched 1071 (Whet), 2743 (Dhry) w/UD Rosetta running in the background (which it always does while BOINC is running). Just to underscore and italicize my weirdness: I'm also signed up for BOINC WCG (so I'll be processing two Rosetta WU's simultaneously). Ha. Anyways, after implementing the 5.2.13 optimized upgrade, I realized that I'd previously been on the v5.2.11 optimized version, which I installed on top of the v5.2.4 optimized version, which I installed on top of the v5.2.11 official. Everything seems to be running o.k. My question: what is that other 9.1MB of stuff that comes down in the official version, and is it really needed? Should I install the official version and then lay the optimized version on top of it, or am I good to go? Oh, and BTW, can anybody tell me how I can tell when the science application checkpoints? |

Windows :
BOINC as SCREENSAVER WIN98SE incorrect operation
(Message 204450)
Posted 6 Dec 2005 by Professor Ray Post: There are some quirks when using Win98, like it doesn't want to allow you to "NOT start up with windows". If you say so... You can go to start, setting, control panel, display and remove it from the screensaver. Man, I never had this happen; maybe because I don't use screensaver? My monitor goes into DMPS mode after 10 minutes (so what do I need a screensaver for?). You could disable the screensaver that way, I just right click on the desktop, select properties, screensaver-tab and select "none".
I read that was spoda be fixed. I have no idea if it is or not, because I still have the famous _DEFAULT.pif fix for that Win98 problem in my C:\\Windows directory. Maybe I'll take it out and test if it actually's been fixed or not.
Easily enough fixed: remover entry from" C:\\WINDOWS\\Start Menu\\Programs\\StartUp Also, win98 memory leaks may require rebooting every week or so. Perhaps leaving clients in memory when they swap out contributes to this. I'm experimenting to see how things go by not letting them swap out. I give each client 270 minutes, and never write out more than once every 10 minutes. Seems like the scheduler does what it wants in that regard more often than what I say in that regard. Whatever. I find it to be touchy, but It's been crunching for a while now. Runs pretty stable on my machine, the only touchy thing that I've found is BOINC's insistance on internet connection ability. As long as BOINC network access is disabled, it works fine and I'm crunching 5 projects (including BOINC WCG simultaneously with UD Agent running Ligandfit or UD's version of Rosetta). All in all, works good. Lasts a long time. |

Posted 30 Nov 2005 by Professor Ray Post: Ideally there should be a link to this info on the BOINC_SETI page. IF it is there somewhere I couldn't find it. Anyways, this link should prove most edifying. If you want to see what its doing, you can either activate the screensaver associated with the project you're running (e.g. SETI among others), or select in the work tab the WU that's running and then click "show graphics" |

Questions and Answers :
Windows :
multiple WU download
(Message 196138)
Posted 27 Nov 2005 by Professor Ray Post: Be carefull on setting it too high. 4 days may be good for SETI alone, but if you're doing something like three projects then two days should be more'n enough. If you're on dial-up, be sure to turn off BOINC network access. And if you have Zone Alarm, ensure that internet-lock pass-through permission is enabled for both Manager & client daemon (its required for localhost loopbacking). What I used to do when I was on dial-up, I monitored the deadline date of each WU, and then uploaded all WU's that were ready prior to expiry of the earliest completed WU. Of course by so doing, the scheduler would seek and attempt to download a whole bunch more WU's. You can monitor what is coming down in the transfers tab. Once it was done, check the messages tab for any deferred items. You should wait until the project is deferred for at least 10 minutes. Then you can turn off BOINC network access again (even if a deferred is out there in the future) so long as you've enough WU for any project to get you through the next day or so. This deferring will happen between the uploading and downloading because the data transfer is chugging the bandwidth of your dial-up connection (so its going to time-out). Certain projects will retry a certain amount of time, and then give up for 24 hours. Einstein was notorious in that regard. It does require a little bit of baby-sitting, but it works. In fact, if you're monitoring your projects closely, you can determine if a project is going to make it or not, and then suspend all the other projects and dedicate CPU cycles to the one that's chugging. |

Keeps asking for proxy
(Message 196097)
Posted 27 Nov 2005 by Professor Ray Post: And then my system crashed, so I rebooted, ran SCANDISK (I have 98SE, the last version of MS Windows I shall run at home - the next OS will be something LINUX-based), restarted, and got an error dialog: "A required .DLL file, LIBEAY32.DLL, was not found."...So now I have to go find out what happened to LIBEAY32, and whether it got deleted as part of the upgrade to 5.2.10, or whether there's a 5.2.11 lurking out there, just waiting to solve my problem... Did some investigation and found that Libeay32.dll is implicated in SSL (secure socket layer dev kits), FileZilla (FTP client) and various parasites. Deletion of the DLL effectively destroys any parasite that's dependent upon it. I'm fairly confident that either SSL or FileZilla will work less than optimally w/out it. EDIT: I searched my Win98SE system and found one in my Windows\\System folder and discovered that BOINC is using it too. Since I'm not a SSL developer, nor have FileZilla, so I haven't a clue what the one in the SYSTEM folder is doing there. I run SpyBot & Adaware, so I doubt its a parasite. |

UpGradeing
(Message 195873)
Posted 26 Nov 2005 by Professor Ray Post: Nope. If you've been running Classic SETI, until it gets migrated, there'll be two computer ID's. One will have all the credit garnered to date. The other one will be the BOINC credit totals. Sometime in the future they will be merged (mid-December)? To ensure that you're Classic account is properly linked to BOINC, you'll need to upgrade your CLassic account (don't just create a new one out of the blue). There is no reason not to come to BOINC now, unless you have some milestone you wish to reach on classic before it closes. If you joined Classic after 15th March then your Classic credits will not shopw up until after Classic closes. But they are not lost and will be visible then. Apparently it is a time consumming job and requires Classic to be off while the credits are extracted to be put on the BOINC/Seti Database. I'd let whatever WU's you have on Classic drain, but not download any additional WU. Once you no longer have any WU to process, link your Classic account to BOINC, install BOINC and attach to one or more of several projects available. |

Boinc locks up my PC
(Message 195858)
Posted 26 Nov 2005 by Professor Ray Post: I have never heard of any computer that has been locked up by BOINC. In fact this is less a BOINC problem but rather a screensaver problem. It could be, and the release notes do intimate sluggishness related to screensaver use. However, the one thing that I'm certain can hang not just BOINC, but the PC too (necessitating ungracefull app termination and/or reboot), is the Zone Alarm internet-lock and/or dial-up networking (internet connection not established) either one alone is sufficient to manifest a hang (it just depends on how long BOINC attempts to process either with interprocess communication w/itself prevented (internet-lock) or to the cloud (internet-lock/no DUN connection). If the condition is the latter, then BOINC must be configured "disable BOINC network access", and uploads downloads must be manually performed (by manually enabling BIONC network access when appropriate - make sure that when BOINC internet access is granted that the ZA internet-lock isn't enabled otherwise presto instant BOINC hang). If the former, then the BOINC Manager & client daemon must have Zone Alarm internet-lock pass-lock permissions. Unfortunately, if you're on ZA free post v5.5.094.00, internet-lock pass-lock is no longer a feature. In that case its recommended to disable internet locking entirely (or purchase ZA Pro - internet pass-lock feature works, and rumor has it that even auto-engage internet-locking does also (at least by screensaver initiation). |

Proxy Configuration issues (HELP ME!)
(Message 195792)
Posted 26 Nov 2005 by Professor Ray Post: BOINC is cool. It is so intuitive its mind boggling. In fact, once the two of you get to know each other, I'm sure you'll get along just fine. In fact, mark my words, you'll begin to wonder just how in the world you got on without BOINC for as long as you did. That being said, it does have its little quirks, the biggest one being it wants to be connected to the internet at all times. So if there's any chance the internet will not be available (for whatever reason), disable BOINC network access, e.g., maintenance work or something, modem will be off, whatever. It is insufficient to suspend BOINC. Even in suspended mode BOINC manager and client daemon are still communicating (the project task merely having been put nappy-time by the daemon). Given sufficient time without a network connection (provided network access isn't suspended), it could ultimately lock your entire system (necessitating an ungraceful shutdown). Don't temp fate w/out a COPY of BOINC backup. You might upgrade 5 times flawlessly, and on the 6th time there's a programming oopsie and you'll need to revert to a previous version. W/Out COPY of BOINC, you'll lose all the projects and current state of affairs XMLs. Because to revert to a previous version it is absolutely imperative to uninstall BOINC completely. One can always upgrade on top of an existing BOINC installation. But if something goes kaflooie, nobody wants to rely on the possiblility of corrupt XMLS being flies in the oinkment. Finally, COPY of BOINC is only of any value whatsoever until the first results update. Once BOINC has updated a single WU results file, COPY of BOINC is worthless. |
