Seti or folding out home on a computer with no harddrive


I have an old 90mhz with 64 mb ram computer that is sitting in my basement. The thing is that it doesn't have a harddrive. Is there anyway to get a minimalist distro that runs on a floppy or maybe knoppix from a cd, cut down almost all processes, and load the seti@home program into memory and run it from that? I checked and seti@home is only 1.6mb. Or could I run a minimalist distro from a floppy, burn seti to a cd and run the program from that. This any of this possible and is folding@home an option.
Thanks,

A few years ago, back in the dark ages, I used to use a copy of the floppy-sized Linux HAL to run S@h on two computers at work over the weekends. They were putzy old 486s, so they didn't run through the work units too quick. I would boot with the HAL floppy, pull that out, then mount a second floppy that contained the program and a work unit. They would crunch away until done, then I'd transfer the results to my computer at home to upload/download. We didn't have any internet access at work. It worked OK... I would occasionally lose a set of results for some unknown reason.

If I were to do it today, I'd boot a standard Knoppix, set-up broadband network access, and run S@h in a terminal. Maybe set-up a ram-disk to hold the result files, and have it save to a floppy every hour-or-so. I have enough projects going that I wouldn't really spend any time paring Knoppix down.

Oh, yeah... http://setiathome.ssl.berkeley.edu/s...eam_68115.html

Yeh, I'm on the team already. I got it working, well at
knoppix. I zip the setiathome app but it was acting weird once
I got it off of the disk. I am goin to go download seti now.
Man, I only have 32mb of ram, no kde.

Soooo close

I have gotten it to the point were seti is asking me for my email and started to recieve the data but starting killing process to fit it in and then killed bash and seti. Is there any way to find what process are running and kill off everything except for bash and seti?
Never mind. I tried it again without the windows manager
and everything works great. Plowing away at 90mhz
thanks for the help

darin3200,

I have an old pII-266 running seti and it takes around 25-30 hours.

Now I have a p120 and I'm guessing that it will take x3 to x4 times to complete a unit. eg. around 90-120 hours. Now a p90? Shudder to think What does it look like it coming to and how many processes have you cut the system down to?

yeh, its bad, but it runs 24x7. About 7 process were cut to make it work. I could cut more to probably make it faster, but, oh well. I don't want to screw anything up. It usally takes about 9 hours on my duron 1ghz although I don't really run it much because it slows down everything. I'm not sure but I think I started seti@home on the computer on sunday

If you check out my stats page, linked above, then you will see a couple old pentiums I have running SETI@home...
Code:
10) Nemo@AuroraBorealis		146 	8480 hr 19 min	 	58 hr 05 min 04.0 sec
11) Nemo@ICF		  	95 	5965 hr 55 min	 	62 hr 47 min 57.1 sec
The AuroraBorealis is a P150, and the ICF is a P133. Both do dual duty as routers running ClarckConnect.

I would love to see what a p4 3.06ghz or a really fast athlon could do running a set@home client.

Well my brother got a 2.66Ghz machine there recently and it does 8 units a day. That's 3 hours a unit. I'd imagine that a 3.06Ghz would take somewhere about 2.5-2.8 hours....

Hmmm... I haven't visited the link below in awhile. It seems to be down... Hopefully, not for good. It used to have a list of different CPUs and speeds and the time they took to complete a work unit. I remember some of the high-end 64-bit chips took less than an hour.
