41) 留言板 : Number crunching : Why not building a seti-RTOS? (消息 458930) 发表于：16 Nov 2006 作者： Calculator Post: I have started to test this. It seems quite okay up until now. Problem at the moment is that the slax itself would need changing, in order to start the scripts. I have to fly into the docs if there is time. I 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

42) 疑难解答 : Wish list : BOINC - Tasks- sort items (消息 458868) 发表于：16 Nov 2006 作者： Calculator Post: I think it would bepretty cool if you could sort the tasks (VIEW) so that the nearest estimated task is top most etc. On some programs you can just push the description bar and the items are sorted automagically

43) 疑难解答 : Wish list : Boinc Linux- OS (diskless) (消息 458866) 发表于：16 Nov 2006 作者： Calculator Post: Okay, didn't expect a client to crash :-)) but thats a good thing to think about! how would a backup look like? -> stop boinc, save files and then start boinc again; or can I just copy the files while seti works with them? (Dont know how file access etc is implemented in seti and boinc) I think I would rather save every 3 or 4 hours as a usb stick is flash... Running diskless saves a lot of HDD power consumption... My file server spins down the disks as I never use them while Iam asleep or @ work, so I dont want to store to the nfs share periodically (of course thats only for my case).

44) 疑难解答 : Wish list : Boinc Linux- OS (diskless) (消息 458797) 发表于：16 Nov 2006 作者： Calculator Post: I have already started to write some scripts for slax. It runs from a 200mb cd or usbstick. the scripts will hopefully create a ramdisk for seti, and when shutting down it stores the seti ramdisk on the usbstick....

46) 疑难解答 : Wish list : Boinc Linux- OS (diskless) (消息 458272) 发表于：15 Nov 2006 作者： Calculator Post: A good thing would be a small linux system that boots linux and runs boinc in ramdisk, so that no harddrive is needed. Save the wu's and boinc settins on a sub stick or something. So that a reboot could be easily done without re-setting everything (or even copy the stick to run many other pc's)

47) 留言板 : Number crunching : Why not building a seti-RTOS? (消息 458266) 发表于：15 Nov 2006 作者： Calculator Post: I was wondering why there is no such thing like a SETI client (optimized for a specific kind of cpu) where I can download 10 or 20 WU's and then the client is started in a DOS-simmilar aerea where there is no windows or linux kernel wasting cpu time. A real time cruncher. I think many old laptops or old pcs would crunch a lot faster ike this? Or maybe receive the wu's via rs232 via data transfer from another pc

I ha problems to unsolder the caps as the use some kind of heatsink on the board (The board itself) use a bigger soldering iron, so you can heat both wires of the caps at a time

49) 留言板 : Number crunching : NVIDIA-CUDA Client ? (消息 458258) 发表于：15 Nov 2006 作者： Calculator Post: does anyone think that a unit like this could be worked aster, I mean most of the stuff seti does is based on fft. wouldnt it make much more sense to develop a seti specific hardware? Something like a fpga that receives data via rs232? if th core is developed just do this kind of work, i guess it would increase the speed, wouldn't it?

50) 留言板 : Number crunching : Current download problem prohibits also other projects downloads (消息 457565) 发表于：14 Nov 2006 作者： Calculator Post: Same with me. I guess it is because the state is "downloading" and boinc thinks the work is going to come soon or sth. like that.

52) 留言板 : Number crunching : Downloading Problems (消息 457474) 发表于：14 Nov 2006 作者： Calculator Post: I guess the logfiles will enlarge dramatically now they get a 403 error from each client

53) 留言板 : Number crunching : Downloading Problems (消息 457472) 发表于：14 Nov 2006 作者： Calculator Post: Same problem here. i was afraid it was problems with my client. glad it is not

54) 留言板 : Number crunching : Optimized SETI - any good? (消息 454526) 发表于：10 Nov 2006 作者： Calculator Post: I have now installed it. Thanks for your support... For the other box, that is only meant to crunch, I deciced to use linux, but there are precompiled i686 binaries available as well thats tight! Hopefully I can manage to build a seti -live cd..

55) 留言板 : Number crunching : Optimized SETI - any good? (消息 454519) 发表于：10 Nov 2006 作者： Calculator Post: I was just wondering, because I downloaded a test_WU from another site, renamed to work_unit.sah but when I execute the setiathome-kwsn-ssse3-c2-v141.exe nothing happens (process not in taskmanager)

56) 留言板 : Number crunching : Optimized SETI - any good? (消息 454513) 发表于：10 Nov 2006 作者： Calculator Post: Tnx fr the answer. The cpu supports sse3 (according to cpu-z) is there a way of testing whether the client works, before I copy it into the boinc directory?

57) 疑难解答 : Unix/Linux : compile error (消息 454506) 发表于：10 Nov 2006 作者： Calculator Post: At the moment i686-linux (suse 10.0) where else can i get the recent seti application source?

58) 疑难解答 : Unix/Linux : compile error (消息 454496) 发表于：10 Nov 2006 作者： Calculator Post: Hey ya, I have just compiled boinc (_autosetup, .configure, make, make install) and now i have tried compiling seti. I have downloaded the souce code setiathome enhanced client cvs 2006-10-31 but it fails configuring with ERROR boinc not beeing found. Any suggestions?

60) 留言板 : Number crunching : Optimized SETI - any good? (消息 454471) 发表于：10 Nov 2006 作者： Calculator Post: Hey there. I saw a lot of optimized seti clients around the web and I was wondering whether they are any good? Thing is. The cruching pc runs 24/7 and I dont wanna spend time on sending broken results or whatever. Are there any recommendable clients?
