Message 18417 - Posted: 10 Feb 2014, 3:02:29 UTC

The second batch of credits was awarded yesterday.

Several application versions updates have been released, most to fix errors where the application would not run at all (Linux i686 and Windows 32-bit). The latest Windows x86_64 versions should fix the issue where the Collatz config settings were not read properly. If the Windows 64-bit versions work properly, the Windows 32-bit, Linux 32 and 64 bit, and OS X versions will also be updated. A new i686 Linux version is required as the current one does not have the GMP library linked properly for those who do not have the libgmp-dev package installed.

The scheduler now prefers Intel CPU over AMD CPU drivers should a host have both installed as the Intel driver is slightly faster.

Finally got wu's that didn't immediately error out but it takes forever to complete (6000 sec)when compared with previous wu's. So a box that used to crunch 250k/day will be lucky to do 90k..thats a big improvement over zilch/day but not enough to keep a credit whore like me interested long term...hope things gewt sorted in a week or so

If you want it to work fast you MUST edit the Collatz config file and add the parameters appropriate for you CPU or GPU. The default settings enable the application to work on any OpenCL compatible GPU, even an 8400 GS with only 16 stream processors. That means that the load on a high end GPU will be low.

See the following thread for info on the Collatz config settings.

Reading your post, I understand it becomes at little complicated to configure BOINC in order to optimize your GPU's "time" ....
Have 2*GTX770 + 1 GTX660Ti and I have no idea what to do with the cc_config info.
The only think I realized is that the crunching time per WU increased a lot,
as well as the CPU time per WU .... (need 1 CPU per WU i/o 0.25 ...)

Nevertherless, thank you for the credits.

Kind Regards

Philippe

I'm a credit whore also, the increase to 15 minute WU's over 10 minute WU's wasn't making me happy either, but I guess I could live with it...

6.04?

ONE HOUR AND FORTY MINUTES?

Not cutting it... Not happy at all...

Had a peak ..... there is something way out of wack with the config you have, time to complete is 6600+ secs per WU is way too slow. I suspect its a combination of settings in cc_config, app_config, and (especially) solo_collatz_6.04_windows_x86_64__opencl_amd_gpu.xml

The latter needs resetting after a mega crash like we all had. I suspect that latter file has a file size of zero, if it does, that's a Major part of the hassle you have. Also likely the CPU share/WU is very low, it needs 0.5 CPU per WU for good results, some machines a whole CPU core - the latter difference from 0.5 to 1 core test by trial and error, but a good improvement by using 0.5CPU per core is *likely*

If you post or PM the contents of all three config files shown above, we could have a peek, and get it back up again

The log file shows:
Using: verbose=1 items_per_kernel=65536 kernels_per_reduction=32 threads=64 sleep=1

That tells me two things. First, it is actually reading the solo_collatz config file correctly now. Secondly, you config file is empty. The defaults, set to work on an AMD HD 4350 or an nVidia 8400GS are the equivalent of:
threads=6
items_per_kernel=16
kernels_per_reduction=5
sleep=1

Whereas you really want the settings needed to keep a high end GPU busy which would be:
threads=6
items_per_kernel=22
kernels_per_reduction=9
sleep=1

The config file seems to have been replaced when the version updated?

Are we supposed to be using (for example, the initially empty file in my project folder) "solo_collatz_6.04_windows_x86_64__opencl_nvidia_gpu.config" or will "solo_collatz.config" work regardless of version? If not the latter, why not?

Grab a coffee, and read this thread from Slicker's first post, it deals fully with how to configure all the three Config Files - its not too long, you will quickly get a guide on next steps

There is a config file per app version, platform, and plan class. When the version gets updated, a new config file goes with it. I tried using a generic one but that wasn't getting read. So, the app is back to the config file matching the app name exactly. In other words, solo_collatz.config will not work. It would need to be in the format:
solo_collatz_<version>_<platform>__<plan_class>.config

e.g.
solo_collatz_6.04_windows_x86_64__opencl_nvidia_gpu.config

In the Issues and Resolutions thread I posted my config....

My CC_Config....

<cc_config>
<options>
<ncpus>-1</ncpus>
<report_results_immediately>1</report_results_immediately>
<use_all_gpus>1</use_all_gpus>
</options>
</cc_config>

My solo_collatz_6.03_windows_x86_64__opencl_amd_gpu.config

verbose=1
items_per_kernel=22
kernels_per_reduction=9
threads=8
sleep=1
build_options=-Werror

I'm not currently running an app_config file.....

Reposted here for ease.......

Under 6.03 I was getting 15 minute WU's just the swap to 6.04 and the time increased dramatically and the fans basically have stopped running....

I know I need to set up an APP_Config file to get all the GPU's running again...
But if I can't get this improved, I'm better off running something else for my $32,000 worth of hardware specifically bought to run Collatz...

Boinc Manager has now averaged out at 1 hour and 24 minutes.... but some of them are still hitting at 1:45 or so... (and giving the same amount of credit no matter the length of time, about 1500 less than the 4.xx app)

If I'm doing something wrong please tell me, I've read the files and set this up way back in June or August where I asked the questions and got the answers I was looking for...

From what I've read, it isn't much different on the setup.......

I have neither the knowledge nor the time to edit anything...I tried to copy the files but nothing happened so I aborted the last 2 hour wu. Sorry I'm an idiot but idiot worked before the crash and I didn't acquire the ability to tweak configuration files because of the crash.

Good luck with your project. You are obviously trying very hard to make it work...

Zydor, I Got it!

And THANK YOU VERY MUCH! I saw what I was doing wrong.....

At this point looks like they are going to come in at an average of 12 minutes a WU averaged over all the machines.......

EXCELLENT....

rofl ..... oh yea of little faith :)

When the dust settles on that lot, we can work on getting down below your 12 mins, the latter is eminently practical without pushing the beasts overly hard.

Buzz me when the dust has settled from that lot, and your ready for the next bit.

Hello,

I am sorry to insist, but this is really the opposite of an improvement, and against "BOINC's philosophy" if each cruncher must start making complicated/perplexing tests and adjustments to try to make the best use of their hardware.

These comments are recurring even between highly motivated and dedicated crunchers, including some from Alliance Francophone.

Both ATI/nVidia users.

I am happy to have the possibility to use app_config.xml files.

But when it comes to .config files ... :/

Not many crunchers know how to manage/configure them ...

I understand, as other crunchers, that you all do your best to have this project running very well.

I tried, using a .config, but I am not sure I will continue to crunch on Collatz if it remains so difficult to configure.

Thank You

Kind Regards

Philippe

Simply math and complicated app, strange. Colltaz is the most difficult project to be run. Why we are to use W7/W8.1 and core 7.0.+ for such a basic math? I like XP and core 6.12.34.
What do tou mean by Legacy AMD Catalyst driver, I am a cruncher, not an IT AMD GPU ClosedCL expert for HD 4770. String Legacy AMD Catalyst driver was not found in the AMD site.

My case is the opposite. Collatz v6.03 App seemed not reading .config file. GPU usage was 92% and a WU took 25 mins. After I updated it to v6.04 and copied the same config file, GPU usage was up to 99% and a WU only took 19-22 mins.

My computer : http://boinc.thesonntags.com/collatz/show_host_detail.php?hostid=138168


BTW, does Collatz rely on double precision compute power?
I saw my HD7850(Pitcairn) ran wayyyy slower than Tahiti GPUs.
