21) Message boards : SETI@home Science : Has Seti@Home ever found anything? (Message 497845) Posted 5 Jan 2007 by Calculator Post: thats what I think as well. I mean no matter what you do, cancer research, or seti or whatever. you kannot be 100% sure that the results are used for humanity-stuff

22) Message boards : Number crunching : Do we already have enough computing power for SETI@home? (Message 497837) Posted 5 Jan 2007 by Calculator Post: Yeah, I'd like to see some extrterrestrial peepshow :-)) I am signed up to other projects as well, but they dont regularily get work as I clicked on no more work...

23) Message boards : Number crunching : heres an idea seti@phone:) (Message 497182) Posted 4 Jan 2007 by Calculator Post: PS: I have a lot of old laptops I would like to run, but the power consumption <-> wu factor is to high. The smallest cruncher I have is a 500mhz old pentium laptop. running nothing else.

24) Message boards : Number crunching : heres an idea seti@phone:) (Message 497176) Posted 4 Jan 2007 by Calculator Post: Seti for symbian would be cool. I would let the thing run all the time on my ngage :-)) just to have the graphics on screen, hehe. the problem that the workunits have to be done in certain amount of time is the most problematic part. If there was a way to run boinc on any of my phones I would let it run... The workunits could be uploaded to the phones using BT or USB, and the phones MMC.. but i guess 64mb of RAM is not what a usual mobile phone will give..

25) Message boards : SETI@home Science : What happens if SETI finds a signal? (Message 497105) Posted 4 Jan 2007 by Calculator Post: I was wondering whether seti crunchers will be informed when a signal has been found?

26) Message boards : Number crunching : The Attack of the Killer 58.7s (Message 486869) Posted 21 Dec 2006 by Calculator Post: 2x2gb?? you could run a complete squashed linux in ram. i bet that runs like hell

27) Message boards : Number crunching : Boinc running off a memory stick (Message 486718) Posted 21 Dec 2006 by Calculator Post: Remeber. the Usb stick is flash and has only a certain number of write cycles

28) Message boards : Number crunching : Boinc running off a memory stick (Message 486715) Posted 21 Dec 2006 by Calculator Post: iam not aware of playing about like that with the windows client. I have a linux workstation that runs boinc of the stick. but its an archive that is unpacked into a ramdisk, so whenever the setiapp writes to disk, i dont use my usb stick. If boinc is finished, the client is stored back to usb stick archive

29) Message boards : Number crunching : Boinc running off a memory stick (Message 486005) Posted 20 Dec 2006 by Calculator Post: thats right i do that as well. install boinc in a different folder like boinc-friend/ and make your settings there. make sure not to run 2 boinc at a time. copy the client to the stick. Set the network access times to 10 days in order to recieve enough WU's. If finished, start the boinc off the memory stick and upload the results. ( set network mode to always)

30) Message boards : Number crunching : best cruncher for under 500? (Message 482648) Posted 15 Dec 2006 by Calculator Post: will the mobo boot without graphics? I know older boards with 440bx chipset woul not. For my server I got a 512kb ISA card (you cannot really call this one graphics) to make it boot..

31) Message boards : Number crunching : Busy Box setup. (Message 482642) Posted 15 Dec 2006 by Calculator Post: afaik damnsmalllinux is doesn't have goot module functionality. Slax comes with some tools that can create a .mo (slax module file) out of a directory. so you add a startup script to the disc (slax customize tool) and you are finally done. on bootup, you could for example have boinc running on console 1, and if it is stopped the scrips created a .mo file and stored it to a usb pen or whatever....

32) Message boards : Number crunching : Busy Box setup. (Message 482014) Posted 14 Dec 2006 by Calculator Post: I use slax.. The server edition fits on a 256 usb stick. I run boinc in ramdisk, so that boinc or seti does not access the flash too often...

33) Message boards : Number crunching : Play Station 3 used to crunch numbers, more info (Message 467400) Posted 28 Nov 2006 by Calculator Post: Why do you need more that 256mb for a cruncher? I have an old laptop crunching and it only has 256Mb of ram that is used by the OS(linux) and boinc running on a 40mb ramdisk. Mem: 253452k total, 194356k used, 59096k free, 26656k buffers There is still some space left... If the linux I run would be more optimized iam sure i could save another 70MB..

34) Message boards : Number crunching : Linux image? (Message 464183) Posted 23 Nov 2006 by Calculator Post: BTW: I will try to build a gentoo based live linux containing boinc and seti... basically that would be the best solution, i think. I just have to install gentoo and that takes some time. if there is a usable solution, i will post a link of course

35) Message boards : Number crunching : Linux image? (Message 464085) Posted 23 Nov 2006 by Calculator Post: Basically, the problem is usb support. YOu need a lot of modles etc and the Kernel would reach 2mb easily. I think it is important to e able to store/restore from a usb disk. If you only work in Ramdisk and PC crashes, the WU and te downloaded WU's are lost

36) Message boards : Number crunching : Linux image? (Message 463363) Posted 22 Nov 2006 by Calculator Post: I use slax and a small script that copies the boinc and seti o a ramdisk. The thematic has been discussed before: have changed the kernel options following: change the syslinux.cfg kernel command line ramdisk_size=44440 (44mb ramdisk is enough) the start up slax(from usb), download boinc and run it within the X windows to set it up and make it running (you ony need to do this 1 time) (after that you can delete the 'boincmgr' to save space) copy the seti directory to /mnt/sda_removable/boinc/ (no extre boinc subfolders) then create a script (store it in /mnt/sda_removable) mkdir /boinc-work mke2fs /dev/ram2 mount /dev/ram2 /boinc-work cp /mnt/sda_removable/boinc/* /boinc-work -Rv cd /boinc-work ./boinc echo Stopped! Echo Copying files to stick cp /boinc-work/* /mnt/sda_removable/boinc -Rv cd / it creates a filesystem on the ramdisk, mounts it and copies the files. then boinc is started. after boinc is stopped (ctrl-c), the files are copied back. Todo: automatically lauch network(on some systems it is not done automatically) download seti&boinc for the first time on its own. if not setup run X with boincmgr to setup. cron -> backup every 1 or 2 hrs to usb maybe later create a setup script that doesnt need the X window any more -> smaller distri. have several different optimizes client versions 1) compile new cpu specific kernels (smp, p4) 2) use optimized cores I am currently running 1 client with that solution. I am trying knoppix / Damn Small linux to see how we can improve...

37) Questions and Answers : Windows : Q: XP keeps crashing after 1 day (Message 462834) Posted 21 Nov 2006 by Calculator Post: I understand. Its a dell laptop. I have experienced before that dell will shutdown and give a boot message if it has overheating problems.. maybe its best to give the laptop 1 or 2 hrs a day cooling down time 'cos its quite hot as you have expected...

38) Message boards : Number crunching : linux question (Message 462373) Posted 20 Nov 2006 by Calculator Post: Well if you dont want to run any servers like http etc, y<ou can use (k)ubuntu which runs very well from what i've seen. I personally run suse (because it so wonderfull colorful) and gentoo - for performance reasons... I also have one cruncher running SLAX which is a live distribution. I run a scropt to create a ramdisk and copy boinc/seti into it. the harddrive is switched off to save energy. When boinc is stopped, the ramdisk is saved to a usb stick (so you can restore again after reboot) currently I look for a automated backup solution, and if everything is running well i will make the iso disc downloadable...

39) Questions and Answers : Windows : Q: XP keeps crashing after 1 day (Message 462329) Posted 20 Nov 2006 by Calculator Post: On one of the BOINC stations I run XP. If I keep this station running 24h it restarts. its a brand new pc, so I dont expect any problems. I really use this unit abusively, and it newer crashed...

40) Message boards : Number crunching : linux question (Message 462327) Posted 20 Nov 2006 by Calculator Post: doyou want to use te linux for gaming and multimedia etc as well, or just run boinc?
