Just wondering if there's any good reason to upgrade anything?

The only other thing to do is to make sure AstroPulse v6 is enabled in your SETI@home preferences

Thanks for the heads up, I took a look and they were all checked, so I'm good to go. It'll be interesting to see if I get any perf improvement. Is there anything I need to do to make sure the AP tasks go to the vid card instead of the CPU? I've heard that they can run faster, depending on the vid card of course, and as I have GTX260's, is there any way other than babysitting it, forcing tasks one way and then the other, and doing the compares, to know which is best?

Is there any particular reason why an AP 6 WU running on a GPU should only use 6% of the GPU?

ITs the first GPU astropulse task wu rig has recieved and I'm a little surprised by the low GPU usage.

Regards,

You're running 285.62 drivers, to fully utilise the GPU you're got to free a core because of the Nvidia OpenCL 100% CPU Use Bug,
otherwise the app will slow to a crawl, or downgrade to Cuda 3.2 drivers (263.xx to 267.24)

Claggy

Well with one core free I get 10% GPU usage:-/ And the 267.24 drivers will not load on my rig, cant find compatible hardware.. Those drivers are for 7xxx or 8xxx not Gforce 5:-( The earliest I can get for 500 series GPU's is 275.27..
Dunno if that one is any better or not..

And an ordinary search on nvidia's site only gives access to the 267.24 driver if you select GF 7/8, select GF 4 or 5 and there is nowt before 285..

I'll just let it run at 10% and when its done I'll remove the ap 6 cl app and revert to CPU for AP 6.

[quoteThe one NV AP Wu you had, did have a huge amount of Blanking, the more Blanking a Wu has the lower the GPU load, and the longer it takes:

single pulses: 4
repetitive pulses: 30
percent blanked: 99.85

Try doing some more, you should find minimaly Blanked tasks take ~45 minutes on a GTX460,

I'll give it a go, but the GPU's are 560's:-) So just maybe a tad faster..

As it stands I will have to wait and see, I 'think' I have 1 more WU of that type..

Thanks Claggy,
I'll bear that in mind, I only have the one AP6 cl task in my cache, and its in the queue, so I'll tweak the ap_info before it hits the GPU.

Hi Claggy,
Used your settings, now getting 95% GPU usage:-) There's only one problem, GPU temps are running at 80-82C.

My GTX560's are factory overclocked so I suppose that might well have something to do with the high temps.

But the AP 6 WU was completed in under 25 mins..

Nevertheless I think I'll try and underclock the GPU's, boinc always manages to pick the GPU most likely to get hot, device 2 has its fan partly obscured by a sata 6gbps card, and I need to have that card for my SSD's..

I've got nvidia inspector, I'll have a go at underclocking that GPU and see what happens with the next AP6 WU in the pipeline.

I've got my fan fixed to 70%, that keeps my temps ~60°C

Claggy

Would cutting the params you gave in half drop the GPU usage by a half as well?

You can try dropping the -unroll value to 8 or 6, that'll lower Memory usage, and maybe utilisation,

Claggy

btw what does the -hp at the end of the line do?

Priority of process adjusted successfully, high priority class used

Claggy

Note that this has nothing whatsoever to do with the 'high priority' you sometimes see against a task name in BOINC Manager.

I've held back for awhile to allow the specific system upgrade issues to settle out, but IMO it's time to inject a more general reply to the subject question.

As noted early in the thread, Al was running the AK_v8b CPU application from the Lunatics v0.38 installer. Last November a small bug was discovered in those apps and Lunatics produced the v0.39 installer with corrected AK_v8b2 CPU applications.

Our hope is that whenever we release new apps, all our users will be paying close enough attention to know whether they ought to upgrade.

I have a couple systems that were set and forget, and I had this one off line for a number of months for various reasons. I'm glad to be back at it, but there are times that it's hard to keep up on the latest and greatest, as life's pretty busy at times. I do try to pay attn if there are issues with what I am running, and would prefer to keep it up to date if possible, when it makes sense to do so. I believed it did at this time, as the AP5s are history, and the AP6s are the rule. I'll probably try to keep it updated on Intel's infamous time frame, namely Moore's Law, and do a major upgrade every 18 months or so. That should keep me current enough, but still not have to worry about each and every update.

Oh, and as far as I can tell, things seem to be working out alright with the updated software. I want to let it run thru a number of AP tasks, they are running on both CPU & GPU, so after I get a bunch of them under my belt, I'll dig in and compare results, and determine which I would like to run it under, then force them all to whichever turns out to do them the best on this machine.

Al, don't forget, we have a new type of work unit coming out very soon so you will have to change things for it. I believe all of us running anonymous platform will have to change but I'm not sure what will happen for those running stock.
