Hello,
My config: - windows 7 64 bits - 2 gtx 580 - i7 980x I want to work more of one task per GPU at same time. I try to put "app_info.xml" fin in the worldcommunitygrid folder. ---------- <app_info> <app> <name>hcc1</name> <user_friendly_name>Help Conquer Cancer</user_friendly_name> </app> <file_info> <name>wcg_hcc1_img_7.05_windows_intelx86__nvidia_hcc1</name> <executable/> </file_info> <file_info> <name>hcckernel.cl.7.05</name> <executable/> </file_info> <app_version> <app_name>hcc1</app_name> <version_num>705</version_num> <platform>windows_intelx86</platform> <plan_class>nvidia_hcc1</plan_class> <avg_ncpus>1.0</avg_ncpus> <max_ncpus>1.0</max_ncpus> <coproc> <type>NVIDIA</type> <count>.50</count> </coproc> <file_ref> <file_name>wcg_hcc1_img_7.05_windows_intelx86__nvidia_hcc1</file_name> <main_program/> </file_ref> </app_version> </app_info> ---------- Now i receive no task and i have errors messages: ---------- 12.11.2012 19:45:27 World Community Grid Requesting new tasks for CPU 12.11.2012 19:45:30 World Community Grid Scheduler request completed: got 1 new tasks 12.11.2012 19:45:30 World Community Grid [error] App version returned from anonymous platform project; ignoring 12.11.2012 19:45:30 World Community Grid [error] No application found for task: windows_intelx86 705 ; discarding 12.11.2012 19:46:45 World Community Grid Sending scheduler request: To fetch work. ---------- Can you help me please ? Sorry for my English it's not my first language. |

Problem solved!! Thank you very much guys.
Detaching and reattaching the project was the solution. I could not detach because I was using BAM! now it's downloading task. |

I am looking for advice how to optimize GPU/CPU crunching, my config is:
----------------------------------------- 980X with HT - 12 threads - ATI 7950 at 10 threads => 10 GPU tasks + 2 HCC CPU task - Win7-64 - boinc 7.05 I am thinking about 12 threads on GPU at cost of 2 CPU tasks, but not sure if there will be no bottleneck. Don't want to do experiments - any advise how to improve system output? Thank's!

The best solution would be a WCG website update where you could choose how many simultaneous HCC GPU WUs you would like to run at the same time - defaulting to 1 of course. That way, "power users" could change it while everyone else could run with no problems...much the way CEP2 is handled today (even though it does not specify parallel tasks, just how many are downloaded in the same WU cache). But almost.

Very not likely, simple because the client / server structure to do so does not exist, and imagine a user having painstakingly created an app_info file, makes a change in the web profile, and poof, gone. you'd be needing similar to the global_prefs + global_prefs_override, 2 files, app_info.xml and app_info_override.xml. Speak to the developers ;>)

So, if WCG wants to do something similar, it's just to talk to Einstein@home.  "I make so many mistakes. But then just think of all the mistakes I don't make, although I might." |

Frankly, what's the gain? You get an "In progress" filter, but at application level. Still does not tell the GPU that they can process X concurrent, or does it?

Of course it's to crunch X concurrently on a GPU. "I make so many mistakes. But then just think of all the mistakes I don't make, although I might." |

Not sure if this is the one, but don't think there's need to talk to Einstein on this for WCG:
GPU utilization factor of BRP apps: 1 DANGEROUS! Only touch this if you are absolutely sure of what you are doing! Wrong setting might even damage your computer! Use solely on your own risk! Min: 0.0 / Max: 1.0 / Default: 1.0 Somehow think it's most improbable to get a WCG device profile slot. |

Because Uplinger already stated that WCG's official stand is that there is no WCG official support for app_info file, users who are contemplating to use the app_info (mainly for customized GPU use in crunching WCG WUs) -- are on their own -- sad as that may be.
To those crunchers who want to venture off WCG-official-support and do app_info anyways, here's an informative PDF link* about the inner-workings of app_info for use here at WCG. Notes: *extracted from OldChap [Nov 12, 2012 11:05:37 PM] post ; |
