Aye well the dice are cast and will fall...as they do.
In the meantime my CUDA babies are 66.6% @ 134hrs, 60.0% @ 134hrs & 45% @ 103hrs.

So expect the first results on Sunday.

According to a thread on the Aqua forums it seems Linux machines are getting and I quote
10x the points of Windows for the same WU
Now I'm not sure of the validity of the 10x but there seems to be something in the fact they get alot more based on CPU runtime.

Its is more probable that they are using modified boinc client's take a look at the top host's

... seems like for v2.27 WUs there isn't much difference between Windows and Linux as similar Windows machines get, more or less, the same amount of credits for the same amount of run time.

The v3.24 / v3.26 CUDA WUs are altogether another story looking at the top hosts and aardvark's WU is on a Vista box with benchmarks about half that of the top hosts... he gets the same credit / run time unit as the top hosts but his run time is much lower.

I haven't found a v3.29 app that gives the exceptionally long run times encountered in the top hosts (this is the version in Aardvark's WU) there are a couple of I7s with 280/295/GTXs that are getting 50.000 / 60.000 Credits at 0.8 credits per run time unit.

... modifying the client isn't difficult (I immagine most Linux users, at least, recompile the client to bring the benchmarks into line with Windows). But then could it be the app itself even if it is the core_client that returns the run time calculation.... ?

No your right Steve but I see you returned resultts in 2 days. Take a look at the other 10x(ish) WU and you will see it's 10 or 12 days to return. Now if the CPU is somehow ticking, which it should not be, but if is and theunits are based on CPU runtime which they are then ....

We incresed our Aqua to 246k yesterbay but UKBT managed 900+k :roll:

... Yep! Steve was right I should have looked further down the top hosts. Looks like a few Windows biggies have turned up in the last couple of days:

440,456 at 1,02 per run time unit this is a 128-4M like Aardvark's run.

520,153 at 1.09 per run time unit a 160-3M

505,450 at 1.41 per run time unit a 160-3M

... this isn't as good as the 1.75 that the 160.3M Linux units were getting but that is probably due to benchmarks. Same turnaround as Jock said around 7 to 10 days (all sent on 24th June a returned between 1st and 3rd July).

... does this mean that the CPU is not playing cricket ? damned dastardly, I say - CPUs should not be allowed tick unless authorised ! :grommit:

If long runtimes are the key that unlocks high credits, then I am ever hopeful. My babies are maturing sloooowly indeed:

240-5M 51% after 117hr
240-5M 78% after 158hr
240-5M 71% after 158hr

And boy do I need some big credits. My remaining GPUGrid units keep crashing after 11 hrs (imagine the swearing that causes) and I keep having to switch off PCs to keep the house habitable.

Never mind, the heatwave seems to have broken and even with all the crunchers on the farm temp has just dipped below 27C for the first time this week! 8)

This does seem comparable to 200-2M WUs from linux boxes:

http://aqua.dwavesys.com/results.php?hostid=11169

Though it does get between 90K and 120K with less than half the run time.

For Windows XP Pro SP2 there are these which are 200-4M WUs like yours:
http://aqua.dwavesys.com/results.php?hostid=16622

There is the "No heartbeat... " message which is common to some of the big scoring WUs on both Linux and Windows. But then take a look at the Benchmarks... are Q6600s that good ? (I thought one of the problems with GPU credits is that the GPU is not included in the benchmark).

From the message board they'll be updating the app on monday though they don't say if they'll do anything about the credits... :?

Hopefully I'm less than a day away from finding out just how bountiful AQUA CUDA is for me:
My frontrunner is @ 89% after 182hrs, the runner-up manages 81% after 182hrs and the one that got switched off during the heatwave is trailing with 60% after 140hrs.

In the meantime the multithreaded CPU version is well worth running

This result yielded 13K of credit on a E6600. The elapsed time according to BM was 36hrs but the Runtime according to the link is 58.3hrs. Presumably this is the total core time, which since it works out at over 220 per core is nevertheless something to be coveted!

Well I had hoped to have a result to tell you about by now. However as I type my front runner still has 0.809% to go which is predicted to take 1hr 39min to finish off. Even a lifelong insomniac like me can't be arsed to stay up well after 2am to see what happens. I'll let you know in the morning unless you find out first.

131.5K for 9 days of GPU crunching isn't too bad. About 50% better than I'd have got from GPUGrid on that machine.

Nor can anyone else! :? Their admin keeps promising more and I think might even have delivered more today but it's all been snaffled already.

Check out this thread for details.

I've got one multi-threaded CPU unit that'll be finished tomorrow and 4 GPU units at 0%, 4%, 12% and 75%. After that it's back to GPUGrid unless Milkyway gets itself sorted.

Looks like you got another 500T / 600T credits due in - congratulations. 8)

Judging from the thread they will have the new apps and WUs up before the end of the week - which should be good news even if they look like they won't be as fast as they had hoped.

I don't think I'll try AQUA at the moment as CPDN is my long runner and I wouldn't feel right ditching them - my P4 zombies would probably drop dead (sic) if they saw an AQUA WU.

Apologies if I drove everyone up the wall with the newbie theorising and thanks for the pointers.

Aqua & CPDN would coexist quite happily and all of your machines would cope with the multithreaded CPU application. So it might be worth a go - if you can get any work for it. 8)

As for newbie theorising, it was way too clever for me. :)

I got quite a few queued up now. The short CUDA ones aren't too bad - I got about 1,200 for what was probably 90 minutes crunching last night.
To revert to the original reason for this thread UBT, are now 2 million in front of us :( but a few big results could overturn that lead quite easily, maybe. :lol:

Just had a crash when a 200-4M got to 100% after about 100 hours. No sign on the tasks list it got the results and its not in my client.

In fact I see:-

09/07/2009 13:41:14 AQUA@home If this happens repeatedly you may need to reset the project.

Ouch! 100 hours of crunching is a lot to lose. :( I've had quite a few AQUA units die on me but usually within a millisecond of starting: Which is thoughtful of them.

In the end I took your advice and am trying out a few 200-4M WUs. Looks like they give fixed credit 26,776 on the v2.29 (multi-threaded) app. They seem to run in between 12-30 hours on quad machines (on a Core Duo more like 50-60 hours). Which is good.

If the output turns up in the task list eventually I would be interested to know if there is a "No heartbeat... " message. (This happened to me on a CPDN WU both output and credits did eventually turn up and I have noted that the "No heartbeat..." message is frequent in AQUA WUs).

You might like to check this with someone who has more experience.

I restarted the BOINC client (actually shutdown the portable, went home and restarted). You loose any data after the last checkpoint so you have to redo a part of the WU but it did deliver at the end.

There is an explanation here as to why the two sets of messages are associated - but I wouldn't reset the project unless you have lost all hope... :( judging from other AQUA v3.29 (cuda) and v2.29 (mt) tasks it is not infrequent :? If the output is like the following (copied from another AQUA cuda WU) you might be OK:

Code: Select all

<core_client_version>6.4.5</core_client_version>
<![CDATA[
<stderr_txt>
No heartbeat from core client for 30 sec - exiting
.. repeated a lot ...
No heartbeat from core client for 30 sec - exiting
called boinc_finish
</stderr_txt>
]]>
If it is not like the above check for -161 return code at the end - that may be a problem....

This is the output from the CPDN task which gave the same "no 'finished' file" message in case you're interested:

AQUA went fixed credit on the evening of the 9th (GPU and CPU Multi-thread WUs get the same credits).

Here is the new credit scheme. at least for the time being.

There has been a big argument between AF and Susa on account of AF getting getting half a billion credits in one day.... :shock:

From what I could make out between 12-30 runtime hours on 4/8 core machines (es. Q6600) with 64-bit OSs. They vary a lot though.
Basically it's good news for multi-core CPU crunchers and not so good for GPU crunchers - some are going back to GPUGRID.

I think the moral is, if you've a GPU point it back at GPUGrid, but let your multi-core CPUs have a shottie at AQUA especially if you are running a 64bit OS (which sadly I'm not at present).

Bizzarrely it seems that even with a 32 bit OS you can get more from a Q6600 CPU than you can from a 260 GPU! The GPU credit/hr isthreatening to significantly, but not disasterously, drop behind GPUGrid so it wouldn't make sense to abort any part-crunched AQUA CUDA units.

Wow! I just got 75K for an AQUA mt WU which took 3 days on a Q6600. So even if we assume it tied up all 4 cores for 3 days (and it didn't) that works out at 250cr/hr per core. Which is outrageous! :lol:

My first 200-4M WU came in today after 5 days (running CPDN on the same machine). This is a 2GHz Dual Core (T5870) with 32-bit Windows Vista. I confronted it with a couple of MilkyWay WUs run using the optimised SSE3 v0.19 app (closest thing I could think of to the optimised Multi-threaded AQUA app).

AQUA is giving me about 4 times the credit/hour relative to MilkyWay optimised (287cr/runtime hour as opposed to 70cr/runtime hour for optimised MW). Mega is right it is outrageous! :lol:

... thanks to Nightlord's post for the MW idea. (Maybe I should have used the SETI SSE3 app as the benchmark but I had run unoptimised MW before - runs about 2-3 times faster CPU only).

There hasn't been any new work on AQUA for a wee while & there won't be until they have finished optimising the various applications to sort out the various - ahem - credit anomalies.

In the meantime Pinkpenguin & I seem to have bigger than average caches of WUs and between us have halved the UBT lead to less than a million. Sadly I only have 2 of the multithreaded one left which will bag me that AQUA million but not do much to restore our UK supremacy.

Hopefully some of the rest of TSBT have some WU in reserve. Failing that we will just have to hope that UBT are as skint AQUA WU-wise as we are!

New Credit scheme for AQUA:
http://aqua.dwavesys.com/forum_thread.p ... =true#3546

It's the same scheme as used in the 8qubit / 16qubit runs over the week-end which averaged at 104 cr/run time hour for the CPU WUs. This compares with 70 cr/run time hour for MW on the same machine. Each run lasted about 30 mins elapsed time.

(Machine=Core Duo - 2.0Ghz / Windows Vista 32-bit / CPU only).

From the message boards looks like the GPU version requires the latest drivers (v190) to work.

Woo Hoo!!!

As Steve's graph explains we are once again a rather convincing UK #1! :wav:
Our lead has become consolidated over the last 24hrs to a somewhat whopping 750K! :wav:
And AQUA has become our 10th 10 Million credits project! :wav: :wav: :wav:

Judging from the results since the 5th August looks like the credit system has been adjusted to MW levels:

Avge credit / run time hour 96-4M units (on or after 5th August): 127
credit / run time hour 128-5M units: 148 (1 unit so far)

This is on a dual-core machine. For MW I can run 2x units at 70 credit / run time hour which amounts to an average of 140 cr/hr on the same machine - more or less equivalent to the AQUA units which now use both cores this makes it more convenient to run them alone rather than share with other projects.

... is this the same for everyone ?
Nightlord

#68

Post by Nightlord »

I can't say for MW on CPU's, but yes, on Aqua, I noticed a big drop in CPU credit in the last couple of days.

There's a lot of discussion over on their forums about credit adjustments. I think they reduced the CPU credit by a factor of 3, but it is dynamic to say the least.

Can't complain though: curently achieving 13k per day from two dual core boxes. :wink:

Can't complain though: curently achieving 13k per day from two dual core boxes. :wink:
Judging from the way credits are going I suspect that the slow build up of longer work units is weeding out the slower machines... this may include 2-core machines (like mine) which are starting to fall behind.

Looks like quad+-cores w/out CUDA and a good amount of L2 cache are doing much better by a significant factor.

Take a look at TomaszPawel's two messages:

At the moment credit is still good and I'm not complaining.... but I think you may like to keep an eye on it as longer run times seem to get less cr/hr.
