Message 1270105 - Posted: 10 Aug 2012, 21:10:36 UTC - in response to Message 1270093.

the ver 7 and above (or what ever ver 7 tried many times, this LT is 100% OK) on yours dl page does not even start at all on this LapTop. So I am tied to version 6.smth. I have tried everything and you can bet your moneys

...

So question:
Is there anyone who can take those improvements to working 6 ver or could someone who is coding now those 7 versions take a second look onto their codes.

This is annoying situation the Boinc-manager shouts everyday to update to the never version, or did it you say: "should update!"


You should really try the Questions and Answers forum for all trouble-shooting related questions. I am willing to bet my money against yours that you have not tried everything, and that there is no way this is due to a code bug in BOINC v7, but likely an issue specific to your computer's configuration.

Sorry man, but did you mean Opengl, not Opencl?


In this very thread I already addressed that question in message 1269250:

No, OpenGL is a graphics library or API designed to be cross-platform to aid in graphics-related apps (CAD, virtual reality, games, screen savers).

OpenCL, the correct term, is an API that is designed to assist or allow running standard applications on the GPU via a common programming language regardless of the hardware underneath (i.e. an OpenCL application can be executed on any GPU that supports the OpenCL standard as long as an OpenCL compatible driver is loaded).


Wow, you're even too wordy here.

NOTE TO ALL: openCL (C as in sea).

Thank you.

Good day. ;)


I would think that as a Professor you would appreciate clarity through information (i.e. "wordy") than to simply correct someone without an explanation. I hope you don't teach like you post.

Thank you.

Good day. ;)

This is not a teaching situation.
Provide the info first.
Then, if needed, follow up.

Seems it would be easier to just provide so no follow-up is necessary. Indeed, as a Professor you should be advocating that all of life is a teaching situation.

With the new applications the ap tasks will be don by the devices that crunch them best. Leaving the cpu's to do the MB tasks and MB .VLAR tasks which they do best.
This is good.

It appears to me that the files being done via GPU are being credited, as my average is about 25% higher now. However, I did notice one thing, on certain files, it uses .05 CPU and it does the decoding in 20 minutes or so, and then I get certain files where is says .04 CPU, and does not the GPU as well, but it takes about 3 hours to process, and instead of the percentage going up as finished conintuously, it takes a few minutes, between larger percentage blocks of completion, IE, from 5 percent and then 9 percent instead of 5, 5.1, 5.2, etc.

The difference in run time is mainly caused by 'percent blanked' (which is done by CPU code so more CPU load and less GPU load) and sometimes by early exit (too many 'signals' found)

percent blanked: 89.55 - Run time 10,660.30 - CPU time 7,464.88
http://setiathome.berkeley.edu/result.php?resultid=2560112163

percent blanked: 0.00 - Run time 4,804.93 - CPU time 1,037.97

This thread about automatically distributed app. No user action required.
If you want to go to anonymous platform and can't get familiar with Lunatics installer then it's better to write in this http://setiathome.berkeley.edu/forum_thread.php?id=67407 or this http://setiathome.berkeley.edu/forum_thread.php?id=68675 thread.
This one about so called stock app that doesn't require to be downloaded by user, it will be downloaded automatically as long as host meets requirements.


I think he was asking (as I am) if we're already running the Lunatics platform, should we just stick with it or revert to the official platform so that it updates to the new optimized one? And will Lunatics continue to be updated in parallel with the official one?

I will have a look at those other two threads but as this one is directly linked from the Notices entry in the BOINC client it would be good to have the info here.

Message 1270880 - Posted: 12 Aug 2012, 17:38:12 UTC - in response to Message 1268857.

We've released the first of four new AstroPulse Windows applications for ATI/AMD Graphics Processing Units that support the OpenCL language. If you've got an one of these GPUs you may be able to process AstroPulse results 15x faster than your CPU alone. If your computer supports a version, it should get it automatically.

The first release supports ATI GPUs on BOINC 7.0.25 or later. The second release (probably next tuesday) will support ATI GPUs on BOINC versions prior to 7.0.25.


Got 6870 cf and no work, is it because i'm runnin on boinc 6.12.34 x64.
Ati driver is 12.6

Will there be Mac OSX programs for using GPU's? I have an i7 iMac and Collatz uses the GPU very effectively.

Sorry. I meant to add that I have an ATI Radeon 5750 GPU.

The first App works fine, but has a bugg in it. When the work file first startes the time remaing column counts down as it should. As soon as the Percent done column starts counting, then the Time remaining column starts to count upwards for several minutes before it releases. When the happens the original time is still slowly incrementing upwards. Let's say there is 1 hr. and 15 min. left to process. The 15 min will increment for 2 to 3 minutes and then release and the original 15 minutes will now be 16 minutes left. Please take a look at this issue, since the program otherwise works fine. I used to spend 30 to 40 hours on a AstroPulse 6 file which is tedious and a waste of resources. Now it takes 1 hr. and 14 min to 3.5 hours to complete the task. Good work who ever did this App.

I've seen this on plenty of projects. It's related to the fudge factor used to estimate the time remaining. The change in direction occurs because without an estimate of completion (i think they call those checkpoints), the BOINC client only has elapsed time as an indication of progress.

It isn't an issue and everything is working as it should. If you want to see weird estimates, try Primegrid. My record is an initial estimate of 5,500 hours for a task that took 80 hours. Oh the days I've spent watching that estimate drop minutes for seconds....

I see. Then answer on this question:
1. If you already using opt apps better to stay with opt apps.
2. Yes, we will make opt app releases under anonymous platform first.
Why we go to stock too: it has MUCH (that much should be much much bigger) coverage. That is, much more GPUs will be involved to help SETI. Even if app in stock release working in less optimized config, this coverage will outweight all and will result in project speedup. But for users who watch for their hosts and can deal with anonymous platform it's definitelly better to use all host potential that possible only via running on anonymous platform. So, consider this thread for "stockers" only.

Consider it as "feature" ;). This will not fixed in near future. App informs BOINC about its progress not so frequently as BOINC updates its state so BOINC counts on itself between updates. Hence you see such progress state changes.
