One thing I've found is that, sometimes, completed Work Units will be credited pretty quickly. Other times, credit for Work Units will back up for a time.

I was actually clipping along pretty good with the Enhanced Work Units. But, the past day, things have stalled. Right now, I'm waiting for a sent Work Unit to be credited, and have a completed Work Unit sitting on my computer waiting to be sent over.

That kind of thing happened to me before Enhanced was implemented, where sometimes Work Units were credited quickly, and at other times, there was a longer waiting time for credit.

Just wondered if that would help any of you who are wondering where your credits are.

is there a way to to check to see what each computer is running for an application (standard vs. enhanced) from the S@H website?

Yes, the Enhanced work units identify themselves in the Application field at the top of the page. Here is one of mine, for example.

Additionally, Seti Enhanced work unit names contain a .3. part like in the mentioned WU 01mr99aa.280.6289.861088.3.100. Standard Seti work unit names contained a .1. part there.

Thanks Peter,
I will keep my eyes open for them.

Sadly, I can recall have SETI Classic WU times of 20+, even 30+ HOURS.....!

A significant proportion of my Classic WUs took between 120 and 150 hours each, on 66- to 80-MHz Macs.

DAYUM...that's dedication, and costly!

The only significant cost was my time (I guess that's the dedication part), as a couple of the systems had to have their work 'sneaker-netted' back and forth, using others that had Internet access for uploading and downloading. The computers would have been running all or most of the time anyway.

Just to refresh my memory, isn't the RAC supposed to drop like half-life decay rates - by 50% per day, no more no less?

The half-life is one week, not one day, for a daily drop a little under 10%—but that's assuming it gets evaluated at least daily... See the BOINC Wiki article on RAC.

Thanks, Odysseus.

I believe S@h (and most other projects) update RAC each time credit is granted, not on a regular cycle, so if a user stops submitting results his score won't decrease, being 'stuck' wherever it was when the last result was validated. See the BOINC Wiki article on RAC.

Ed. Note: This is coming from a guy who used to wait two days for a single rendering of a Mandelbrot fractal on a 1MHz 6502.

Heh. Almost the same here, but more like half a day, on a 20-MHz 68030, with 3D shading. ;)

The good ol' days... but I digress.

I don't see why, we seem to be getting back to the crunching times of the original Seti Classic, way back when...


That's 7hr 23min per wu on average!

It's just that now (most?) people have faster PC's and we are doing a more thorough/in-depth search.

Sadly, I can recall have SETI Classic WU times of 20+, even 30+ HOURS.....! And this was before SETI Spy and SETI Driver made life much easier so you didn't have to "waste" crunching time depending on when you had an opportunity to dial in (to the 'Net), upload ther esult and download another ONE WU...!

My, how times have changed (a bit !!)

Yes, the Enhanced work units identify themselves in the Application field at the top of the page. Here is one of mine, for example. When browsing your Results pages, look for In Progress deadlines that are earlier or later than the usual 14.0 days from when they were sent. (That won't necessarily catch all the Enhanced results, but AFAIK the standard deadlines are invariable.)

i think that if this change provides more reliable operations (servers, splitters, etc.) then the increased time and the decreased RAC is worth the change to enhanced.

btw is there a way to to check to see what each computer is running for an application (standard vs. enhanced) from the S@H website? i don't have access to one of my computers right now and i was curious if it had switched to enhanced

Back to the point, I really don't care how much time WUs take, as long as they resume correctly when interrupted. If the stated purposes are achieved, doing more thorough analyses and reducing the number of transactions the servers have to handle, that'll be a Good Thing on both counts IMO.

I'm sorry Michael, but having crunched 8-hour-long WUs for over a year, I have to agree with kinhull.

It may be for the science, but nowadays, we associate computers with speed.

Your right...I should have expanded on that statement..KB7RZF did it for me :)

first 2 wus to complete under seti enhanced took 4.5 hours each (270 mins). I am waiting for credit for one of them but i did get 55 for the other.

With standard seti, i was doing approx 6 wus per 4.5 hours. I was getting about 25 point on avg.

so, very bascially, from 33.3 points per hour to 12 points per hour.


With an optimized client i guess that could climb as high as 20 per hour..


as far as i can see, all those who were onboard early with standard seti will have acrued a big points advantage over us recent joiners.

Only thing I can really say, is wait and see what happens. Theres people testing optmized applications. Who cares if its slower right now? When Seti@Home BOINC came out, there were no optimized apps. It took time. Same with Enhanced. It takes time. Let them work the bugs out, and I would say within a reasonable amount of time there will be optimized apps to cut the times down. Maybe not as fast as they are with standard SETI, but to cut times from 8 hours to 4 hours is a hell of a step in my book.

i suspect people will stop crunching if they take as long as the first 2 did on my machine.

Sometimes I think we are alone in the universe, and sometimes I think we are not. In either case the idea is quite staggering.

i suspect people will stop crunching if they take as long as the first 2 did on my machine.

previously taking 48-53 mins per wu.

first 2 wus on enhanced are at 2.5 hours and 33%...

nice.. i'm assuming i'll get soemthing like 3000 credit by the time the eventually complete.
