You've crunched a WU that took 7 times longer than normal?

I've been running V1.4 for 24 hours now!:D Are these "real" WUs? Or am I doing something wrong? I chose:

Devices 1
Count 1.00
x41g
Use all 18 workunits
Test with the values above

Shorties take around 1700 sec on my mobile GPU, middies around 4600 and "normal" WUs (the ones that give out around 100 credit or more) 7700 sec.

I've only managed to get through 7 WUs in 24hrs but the times are nowhere near the above. So far I've got:

(PG0395_v7.wu) 803 Seconds
(PG0444_v7.wu) 704 Seconds
(PG1327_v7.wu) 984 Seconds
(FG00091_V7.wu) 20770 Seconds
(FG00134_V7.wu) 22019 Seconds
(FG01307_V7.wu) 18278 Seconds
(FG02968_V7.wu) 15836 Seconds

Are these test WUs some sort of Seti outliers? I've never seen a WU hand out 300 credits... not even with CreditNew!;)

The PG set are shortened WUs, the FG set are full length. The names indicate the angle range with an implied decimal point after the first digit. So FG00091 and FG00134 are VLAR tasks which would not normally be sent to CUDA, the others so far are rarities; the set was chosen to provide samples across the range, not to represent typical distribution.

The _v7 in the filenames indicates that the autocorrelation search supported by SETI@home v7 will be done in addition to the other four search types. That will mean that even the WUs with more typical AR will take longer to process than SETI@home Enhanced tasks of the same AR.

This has me confused.. Just for fun I tried this on two computers both with GTX 260's and both comp's came back at .5 as the optimal setting.. So I decided to actually try it on one comp and so far it is a tiny bit faster running at .5.. I'm lucky in that I have a group of work units that are all the same day and angle.. It crunched 8, two at a time, at 6:35 each.. And so far it's crunched 4 or 5 more, 1 at a time, at 3:44 each..

How is this possible? Everything I've ever read says the 200 series can't do 2 at a time or that it wouldn't help.. Yet I'm seeing a positive from it and the card is staying in the upper 70's with default fan settings..

Normally it's even slower running more than 1.
My guess it got something to do with feeding the GPU. Maybe the CPU doesn't got the time to feed the GPU properly.
And with 2 CPU tasks it may get more time allocated.

This means leaving a CPU core dedicated to the GPU feeding may help.
Or set a higher priority on the feeder task.

You can try this program: http://www.efmer.eu/forum_tt/index.php?topic=198.0 and set the priority higher.

Yeah me too. I've got the same dumb look on my face you do. I tried to kickstart this conversation quite a few posts up when Fred tested his laptop and all I got was... tumbleweeds. So I too decided to to try 2 at a time (like you said "just for fun") on the tiniest of mobile GPUs from the 200 series and whadayaknow... 2 was a bit faster than one for me too. I thought it was big news, but no-one seems to care.

The good news is that thanx to Fred we finally have a much needed Seti benchmarking tool for idiots. Fred, I know you have been "advertising" this tool as a one-off way to check "count" but I think you have created a monster of a benchmarking tool for us Seti noobs without even realizing it!:D

From a post I made over 180 days ago in the Lunatics Windows Installer v0.40 Release Notes thread:
... If I had a "pretty" benchmark app I would go OCD on the thing. I'd check every WHQL nVidia driver from late 250's to current 290's. I'd turn Windows eye-candy, services and processes on and off. I'd play with nVidia settings. And whenever Jason-G would come out of left-field with, "Oh, you know, it could be your Wi-Fi that's interfering with crunching" I'd check that too:) I say "pretty" because I don't know how to work with black & white windows. I need installers and progress bars and buttons I can click on and things to hold my hand:) Of course I'm sure you guys have next-to NO time for such a thing...
And thanx to a thread Jim_S created a couple of days ago, I got the idea that you can even use this tool to check how many CPU cores are optimal for GPU feeding.


So Fred, you just crossed out the biggest item on my Seti wishlist!
Thank you!:D

PS @Zule I have NO idea how this got by our gurus. My theory ATM is that no-one thought to check/benchmark "count" when the 270 drivers came out. Those drivers came out almost 3 years after your 260 did...

Message 1288379 - Posted: 27 Sep 2012, 10:52:20 UTC - in response to Message 1288363.

The answer has been posted on the boards before, but it's worth saying again. Here's one relatively recent iteration, from message 1259625:

it seems that multiple simultaneous WUs don't scale well unless on Fermi or later cards.

Yes, that's the way they were built.

Tasks don't actually run 'simultaneously' (any more than they do on a single-core CPU under a multi-tasking operating system). The hardware is switched from task to task on a scale of milliseconds, perhaps even microseconds.

Fermis and later have specialised silicon to handle this task-switching at high speed: earlier GPUs don't.

So, the bullet points are:

* 200 series can run two at once, and have always been able to - provided there's enough memory
* The benefits are marginal at best, and much lower than the speed-up you'd get on a Fermi

I think Fredo may have come up with the answer when he said it might help if you dedicated a CPU to it.. I'm currently only crunching GPU on this comp so I have a Phenom II 965 feeding the 260...

As for the drivers, I've done some benchmarking and 275.33 are the fastest for me. Seen a few other people say the same thing, yet everyone wants those latest drivers;)

So we accidentally found a flaw in the testing process since when the tool runs the CPU is dedicated to the GPU. Uninformed users may take the results from 200 series cards and below and use them in normal operation. Without a dedicated core/cpu like me it may have negative results..

Btw.. Love the tool and love Boinc Tasks:)

@Zule I think Fred misunderstood what you were saying. It looks like he answered to "why is my GPU slower at doing 2 WUs at a time" which isn't what you asked:) I could be wrong though... Fred?

Looks like a toss up between 2 & 3. Only a few seconds gained for the extra WU for 3 at a time, but overtime i guess it would all add up.

There is nothing automatic about this test. Notice how nearly 100% of this discussion involves Volunteer Testers. Perhaps version 1.5 or 1.6 could actually be automatic. There are millions of programs out there that all one need do is download and run and they work, perhaps one day this will become one.

Fred, thank you for working on this very neccesary pieces of software.

Hey Snowmain!

Please don't take this the wrong way, it's one of those "Is your computer plugged in" kinda questions...Here it is:

Did you drag the folder out from inside the zipped folder and place it (say) on your desktop?

Edit: In other words are you trying to run the tool straight from the zipped folder?

If and when this program become automatic, somebody pm me and I will gladly run it and post up my gtx 570 classified both at its stock 822MHz and at its current 839MHz.

Are you using 1.4 ?
Simply unpack the zip in a folder and run it.

Sometimes something unexpected happens.

Use explorer and try to open this folder: C:\videocardtest\SetiPerformance_32_64_1_4\zip\x41g\
Try opening C:\Users\Jim\AppData\Roaming\eFMer\SetiPerformance and check what is in slot0.

Helping me solve this will help others and will make a better V 1.5

I thought GTX660 was faster than a GTX560, wonder if we tested using the same WU?


What I see so far is that the 6xx series is actually slower on the g.
It has more cuda cores but they are less capable.

The Beta Z series suggest that the 6xx series will be a bit faster with that program version.

The log files (SetiPerformance.log & result.log) use strange sequence at line ends (line break):
0D 0D 0A (CR CR LF) instead of the usual for Windows 0D 0A

I can't find them.

\r\n \r\n\r\n (D A) only. Give me a specific location.

MY advise.....

First) Skip the zip. Bandwidth is not an issue for anyone using seti. Its an unnecessary step that just adds complexity. Even for the host this file might have been downloaded 200 times, its just not enough data to make the zip necessary.

Second) Compile the entire program into a single executable file. This would then put all of the necessary files in one location... This would allow the program to be run from the desktop, or any other location.

I am sure my solutions here are highly simplistic to the more PC savvy among users.

But make it easy or im just not interested...ya know....like almost everyone else.
