I've already processed 3 units! I am interested in how long others are taking to process a unit. I am on a 266G3 running OS8.6 and it is taking me about 26 hours to process a unit. Compared to the average of other PPC processed units I am taking about 8 hours longs. I would expect to be processing them as fast or faster than the average considering I am on a G3, one of the fastest PPC computers.

Well, **** you

My P100 has been processing for 48 hrs, and is 19% done w/one unit.

Oh, well. I'm getting a new comp this summer. PIII550!

Bah! I've downloaded it twice and it won't install. I've resorted to asking someone to download it for me, then sending it my way.


Been waiting for this a long time.

I am processing my first unit right now. It's going to take a while, although I am running it all the time (I have the RAM to do it, and my processor is decent too).

Arrhh the idiots have taken too long. They've got it downloaded as ftp and the firewall was changed to stop that about a month ago !!!!

Got it working, on my first packet of data, close to ten hours now, at a little over 10% done. With a Pentium 200.

Strange though, when I took the screen saver off, my mouse froze, and I couldn't connect to the internet. A leason there, don't turn on the screen saver, since you'll probally just keep it running in your system tray.

With my o/c Celeron-A 450, under linux, it's running at just a hair over 8 hours/unit.

I don't know what the problem is, but it has been 25 hours on my, and only 56% done. I'm not running something anemic; I have a PII/350 w/ 128 MB of RAM. I am not doing any processor-intensive stuff; in fact, outside of a few hours of web-browsing and chat (mIRC) I have't used the computer at all.

Bummer.

Thanks for the tip guys, Seti@Home is one of the best idea I've ever seen. Getting idle machines to do a useful task instead of running screensavers - Excellent !

Every capable PC in my office is now numbercruching the seti data.

Umbra1: Wondering what would happen if anyone found an ET transmission ?

GaryD posted 05-18-99 10:33 AM ET     Click Here to See the Profile for GaryD    
Ha I've found one.

It says "You have five days to lodge an appeal before your world is demolished to make way for the intergalactic highway.

It's alright GaryD the highway will bring a lot of tourists to shops in the surrounding area.

Dunno. It may be that the windows code is inherently less efficient than the *nix code or in some other way be OS dependent.

Just so everyone knows, I read on a BBC article about this, that a small "five minute download would provide enough data for a couple days of processing"(paraphrasing).

So, I believe this is normal; the time it's taking to analyze the data.

My lil' celeron 333 has taken 5 hours to do 10%. I hope Seti isn't in a hurry for their data...

My lil' old P166 (32mb, win98) has done 14% of 1 unit in 13 hours of processing. Has anybody found ANYTHING interesting?

With the number of people having a go, SETI is going to get plenty of data, plenty fast enough.

I'm mostly playing by email now so my PC has plenty of time of look for ETs...Still nothing yet except for a brief message reading "Bake me to your lemur" or something like that.

I finished my first unit in a bit over 42 hours on my AMD K6-III 400MHz/128 MB/Windoze 98. I guess they didn't put in any 3DNow optimization.

Speaking of finding anything interesting, does anyone know what the hell they're looking at? I've gotten several high spikes on the graph that shows up, but I'm assuming that "Strongest Peak Power" and "Strongest Gausian Power" are the things that we should be looking at.

Check out the seti@home site (see top of this thread for URL) They've got detailed information there about what the data means and what they're looking for.

Hey, I put my name in a long time ago, and got no email! No fair.

Spoe, I envy your specs. Fortunately I should be getting a nice new beast myself somewhat soon.

GaryD: I tried to raise the Alpha Centauri Galactic Highway Office, but their reciever must be down. I guess that they'll delay the construction of they hyperspace bypass until they get communications going again... right?

Just a guess, but it seems to me there is a good chance that they are using more than single precision floating point(all that is supported by 3DNow!, MMX, and KNI) for the majority of the calculations, so there'd not be much advantage, if any, in using 3DNow!.

I have completed 3 units so far. My average time is 29 hours per unit. I'm running a Celeron 300a (@450) with 128MB of ram and Win98.
This has got to be one of the best ideas I have ever heard of. The man that thought this one up should get a raise!
Has anyone else noticed that it can be downright impossible to connect to the server to get new info during primetime net use? I have a feeling a lot of people are doing this!

"My average time is 29 hours per unit. I'm running a Celeron 300a (@450) with 128MB of ram and Win98."

I guess this confirms my theory that the *nix versions are inherently more efficient than the windows versions. With my box(300a o/c to 450, 128 Mb, Linux), I'm averaging between 7 and 8 hours per unit(overall at about 13 hours due to mixing in data from my desktop at work).

Spoe, have you tried a Solaris 7 box?

DanS: Nope. Don't have access to a Slowaris box.
DanS posted 05-25-99 09:53 AM ET     Click Here to See the Profile for DanS  Click Here to Email DanS     
So it's slower?

DanS:
Dunno. Last time I worked on a Sun OS it was SunOS 4.03(IIRC, the version of SunOS before Solaris was released), during the transition from a BSD-based system to SYS5(again, IIRC. It may have been the other direction) on a SparcStation IPC. That was hardly a speed demon, though a switch to gcc instead of the then-bundled Sun cc increased performance substantially(IIRC in the neighborhood of 10-20%. Of course it had no effect on I/O performance, etc.).

Since then I've worked a little with HP-UX, Digital Unix, FreeBSD, linux, NeXT(on genuine NeXT hardware).

I finally have it, though it may take me as long as 80 hours to get that first unit processed.

I suggest we get together and form a team of people from the forums.

JB posted 05-28-99 11:15 PM ET     Click Here to See the Profile for JB  Click Here to Email JB     
That would be good. Who's going to form the team?

So far, I have 14 or 15 units completed, thanks to the computers at my school (iMacs rule! =)

jig posted 05-29-99 04:04 AM ET     Click Here to See the Profile for jig  Click Here to Email jig     
I'll join the team...
Victor Galis posted 05-29-99 10:02 AM ET     Click Here to See the Profile for Victor Galis  Click Here to Email Victor Galis     
I think I'll start a new thread dedicated to the team.
