Got a bunch. Seem to be a lot longer than the ones yesterday thoughsteve wrote:Megacruncher wrote:It didn't last. I hope I'm not the only one of us who grabbed it!
More now available --- get em while they last...
Even managed to grab a CPU unit
Not that Im complaining, got about 8k credits for 10 hord crunching last night :)

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.

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:-

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.Megacruncher wrote: In the meantime the multithreaded CPU version is well worth running
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).jockmacmad2 wrote:Just had a crash when a 200-4M got to 100% after about 100 hours.

I have the no heartbeat on both Aqua and I think my failed GPUGrid tasks. I will look a little later.

You might like to check this with someone who has more experience.jockmacmad2 wrote:I have the no heartbeat on both Aqua and I think my failed GPUGrid tasks. I will look a little later.
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>
]]>
This is the output from the CPDN task which gave the same "no 'finished' file" message in case you're interested:

I'm getting 26k credits for the 200-4M-64 units. Had 3 finish now and they all give the same.
#53
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....
EDIT:
Basically it's good news for multi-core CPU crunchers and not so good for GPU crunchers - some are going back to GPUGRID.

EDIT:
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.aardvark wrote:What type of CPU are these running on, how long did these units take ?

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.

My bloody E6600 wont get any aqua work, both my dualcore seem to get it allMegacruncher wrote: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!
btw, I had to abandon CUDA coz it stopped little things like being able to see the screen.... not recommended for slower graphics cardss methinks

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).My bloody E6600 wont get any aqua work, both my dualcore seem to get it all
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!
... 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!

Of course Reeltime & John McLean helped too! & we shouldn't really forget the 60% of our AQUA previously contributed by Merlyn! :)

New WUs available for the weekend - only 8qubit (CUDA) and 16qubit (MT) until after the weekend. :)
[Edit]
....here are the some units returned with the new MT app:

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.

New 72qubit CPU/CUDA run started last night - in case anyone's interested.
Please note the new creditt scheme (see previous post) and the following on variable credits based non the number of sweeps:

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:
Well done TSBT dudes & dudettes!

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 ?

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.
P.S......got another ATI card arriving today

Better get my motherboard RMAed quick to get my other cards back online as your starting to worry me :)

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.Can't complain though: curently achieving 13k per day from two dual core boxes.
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:
http://aqua.dwavesys.com/forum_thread.p ... =true#4076 and the one immediately following.
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.
#71
I had to suspend Aqua last night due to MW not playing nicely with LTD and causing mayhem with the scheduler. I think I could knock up a short script to fix that, but don't have time now.
Meanwhile, I dropped a Quad core onto Aqua to see what the performance would be like and it picked up a couple of huge 160 qubits. After 6 hours it was only 25% through. For various reasons, I don't want to run that rig 24/7, so I suspended it overnight to take another look this morning.
Long and the short of it is I think you're right as these bigger WU's get released, the dual core's may struggle.

For anyone who is still running AQUA - the queue has run dry... probably until after the weekend as they are releasing new apps:

In a way it's a relief - being able to rededicate my CPU cores to CPDN without thinking I'm missing out on/depriving the team of greater gains. :)
