Here's another one: http://setiathome.berkeley.edu/workunit.php?wuid=2664443000
It was run on 1080Ti in 115 seconds. The 156 second one was run on 1080.

The servers have a lot of tapes with DIAG_KIC8462852 data.

. . Hi Petri,

. . So from what I am hearing these new tasks take about the same amount of time to process as a normal blc04 task, and we are in for a flood of them. Things could be worse. They could be blc05 tasks (shudder).

Stephen

:)

Now that I've had time to look at several of them, they take about 30% longer than the normal BLC04. Interesting..

. . Hmmm,

. . That makes them even slower than Blc05 tasks :( ... ouch.

Stephen

. . But maybe they will be the ones that make the difference ... ???

. . Now that I have had a chance to observe run times they seem to be very comparable to Blc05 tasks. And I hope all those who were unhappy at the dearth of GBT work are smiling now ... my rigs are running 60% GBT tasks ....

Stephen

<ambivalent shrug>

Hopefully a few more files will be loaded up before the weekend.
Even with the increased runtimes of the new GBT data, I can't see the current GBT & Arecibo files making it through the weekend.

Hmm.
Looks like they've finally released the 4bit WUs.
Testing was done over 12 months ago- the advantage of the 4bit WUs is that they result in a 46% reduction in the noise in the WU when they are processed.

And I notice BOINC v7.8.2 has been released, but no info on the changes/updates about it on the download pages.

Yes, 4-bit WU's released indeed. Twice the size, twice the fun :-)

And twice as long to crunch?
Meow?

No difference that I remember from the beta test, or at least very little.

If that's the case, let's hope that Seti can find twice the bandwidth...............................
Still do miss those old bandwidth graphs.

If I remember they were only a couple of percent longer run than 2-bit units.

. . Yep, run times for those I received in Beta were very similar to the 2bit variety but resolution and noise reduction were apparently much superior. I have been wondering if/when they would materialise.

Stephen

Hmm, with double the demand on the bandwidth, I really wonder if this is going to work?
I really doubt it.

That is my concern. Things have been running so smoothly as of late, I just dunno if it will hold together doubling the data sent out.
We shall see soon enough, I guess.
The kitties are sniffing growing pains in the air. Hope they are wrong.

Meow.

Quick general question along these lines. I've always wondered, since server strain had been a perennial issue for the project, why haven't (at least as far as I know, but I honestly haven't followed this very closely) the powers that be just made up the work units to be effectively 'bigger', which reduce the numbers of up and downloads? I would guess that the individual file sizes might be a little larger, but if the we could reduce the I/O by a factor of 2, wouldn't overall this be a good thing? I can't imagine that I am the first person who's ever thought of it, so there must be a reason that it hasn't yet happened. Thoughts/opinions?

Has been mentioned before, and I actually thought that was what was happening with the new change.

I would imagine changing the time period for a task would cause quite a problem with the database storage and/or extraction/comparison of results. With the data units being the same size it is probably the best to keep it that way.

I'm certainly seeing download issues with doubling of file sizes and my 5Mb/s pipe. It does affect normal surfing much more than before.
I may have to try going back to 2 concurrent download per computer.

The 4-bit tasks are not the "bigger" ones that have been talked bout by some. The so-called "bigger" tasks were thought to contain twice as many (or more) data points of 2-bit resolution, thus take about twice as long to process, but with no increase in resolution, but a reduction in the number of work units generated per "tape" as each task overlaps its neighbours by a fair amount thus by increasing the number data points the number of overlaps is reduced. I believe that one of the reasons for the "bigger" tasks not be released into the wild was/is that many of the slower machines would suffer an unacceptable level of time-outs. As has already been said the 4-bit tasks have the same number of data points, so take about the same time as two-bit tasks.

Well, there has to be a way of sending that work only to machines that could handle it.
Would require rewriting some Boinc/scheduler code of course.
If the machine sent back a tidbit of info about itself with the work request, the scheduler could decide whether or not to send it.
Average turn around time might work.

"Freedom is just Chaos, with better lighting." Alan Dean Foster

That makes absolute sense to me, but from what I've heard about our current resource/staffing issues, is there the headcount available to do it? Would this be something that we might be able to somehow roll into the new(ish) project that the generous Russian gentleman had financed and was implemented last year? Or would this be somewhat outside the scope of that project?
