Re: GPU Optimisations

Maybe drop it to 3 GPU only. Might work. Your system could be choking doing 4.

Re: GPU Optimisations

After the "seem-to-be successful" implementation of app_info.xml based on Bercat/Nanoprobe input, the host computed all the tasks but failed at the end by reporting them; bringing again the "anonymous" message.
About the app_info.xml file and using it, I'm still missing why some machines are successful and other machines are not confused.

My understanding is that the use of an app_info.xml can not but result into the so-called 'anonymous platform'; and while a number of people have used the app_info.xml file with success here at WCG, it is not clear if WCG officially supports 'anonymous platform'. The app_info.xml files I have seen here at WCG essentially mirror what WCG officially has and it becomes a matter of writing into that app_info.xml file what WCG officially runs plus some configs for machines (like running multiple HCC-GPU-WUs) -- and as such, there is, in effect, nothing 'anonymous' about the data in those app_info.xml files that are used (or recommended by crunchers for use) at WCG. I'm thus wondering why the added machine configs in an app_info.xml file could not be made to be handled by the old reliable cc_config.xml confused. Perhaps in the near future?

Re: GPU Optimisations

I was using this app_info, it was working (2x tasks using the GPU, 2x tasks using CPU only), but then by the morning everything had stopped.

I'm not sure when it stopped during the night.

Any ideas?

Re: GPU Optimisations

It's at the very least curious you refer to a 7.1.0 API when the science application version 6.56 and 6.12 [GFAM] indicate that they were compiled using the 6.x api. But frankly, this is a pure guess, only based on the new version of HCC being numbered 7.05 indicating it's using the ver.7 API.

Re: GPU Optimisations

7.x is needed for Win8 installations.

Re: GPU Optimisations

That I know [and have a W8 system here running WCG], it's just that the science is compiled with the 6.x API FAIK. Your file seems inconsistent to refer to 6.13.0 for the GPU science, which is with which it was compiled [the BOINC wrapper.

Have asked Uplinger to confirm in the Beta forum where HCC/HCC-GPU v 7.05 is tested.

Re: GPU Optimisations

Have a question too. It doesnt matter me to much, but perhaps someone knows why ^^

Im running 4 WUs at once on a HD7950 on a P5K Mainboard with 2GB DDR2-800 Dual Channel and a Q6600 CPU. Running one WU gpu load is 70%, with second its 80% but with 3 and 4 wus it stays at max 80%. I wonder what the bottleneck is when every WU gets his own physical CPU Core. is it because no PCIe 3.0 slot or something?

The GPU project is designed to use both CPU and GPU. It starts on the CPU, then most get done on the GPU, then back to CPU to finish. That 7950 is a real strong graphics card and capable of doing 12. I'm doing 10 on mine. Yours is just clearing its throat at 80%. From tests I have read about, not much difference between PCI-e 2 and 3 on tests conducted. Maybe the newer cards coming out can utilize PCI-e 3 bandwidth better.

Re: GPU Optimisations

i know it uses CPU too, but it using cpu at beginning and on the end ;) but between it using 80% only, i mean the progress between 0,001% and 99,415. It definite uses only 80% in this phase ^^ I will try more WUs at monday at once because i read it is makeable with a change of avg cpu in appinfo. But im sure it will stay @ 80% ^^
