Re: BOINC Future Drool - OpenCL enabling started for Ivy Bridge

nope. I wrote on the BOINC forums to seek for an Intel GPU project. I'm awating an answer.

Re: BOINC Future Drool - OpenCL enabling started for Ivy Bridge

Let's emphasize, this is very much a test client. An Intel HD4000 identified as a ATI_GPU is already a set up for failing tasks, to which I have little doubt. Reporting to the developers is surely appreciated.

edit: When mentioning "Reporting to the developers", I mean their alpha mail list. They hardly read the BOINC forums.

Re: BOINC Future Drool - OpenCL enabling started for Ivy Bridge

To add to previous post edit, those interested to feed back to developers [those running the latest greatest, or not so great alpha clients], please consider this post on actions for alpha testers: http://boinc.berkeley.edu/dev/forum_thread.php?id=6258#36237

And on the note of testing, and the new feature started with 7.0.40 to be able to control the number of tasks of a science [see change log notes on app_config.xml http://boinc.berkeley.edu/dev/forum_thread.php?id=6698&nowrap=true#46649] with this it would now be possible to set how many concurrent tasks on a GPU or a CPU of a specific science app. E.g. if you load up with 4 CEP2 in your buffer, but specify, for not more than 2 to run concurrent, this client would only start a maximum of 2, even if the other 2 would have their turn in the FIFO order of processing. This e.g. makes sure that you can maximize on a particular science without having to micro-manage to prevent crippling during use. The app_config.xml file also has to be in the projects/* folder. I'll be hoping to test this in the coming week.

edit: FTM not getting app_config.xml to work. Start 1 CEP2, with a limit to only run 1, took copy of the application mask from Task Manager, pasted into the proper line. Restarted BOINC and forced a second to start. 2 CEP2 are running. Put a copy in both the data_dir and the project dir to make sure [the wiki does not mention where to place the file], restart BOINC... 2 running. Then per the wiki put the "short name" i.e. cep2 [per the client_state.xml info], still 2 running on restart... going to sleep on this.

The bolded bit has already been fixed for the next test release: http://boinc.berkeley.edu/trac/changeset/5c13...403c645baddd47c122/boinc# (HT to Claggy on the BOINC forums].

The GPU-Z program tells me the 2670QM CPU has a Intel(R) HD Graphics Family on board but no version/series number, except one box mentions GT2.

For me it's working. My WCG prefs are 4 CEPs. I loaded 2 CEPs, waited that 1 was running and suspended all 'ready to start' SIMAP's and 1 running SIMAP.
The second CEP didn't start. On my quad 2 SIMAP's and 1 CEP2 running and 1 idle core.

Perhaps you oversaw the error on the BOINC-wiki page, where an s is missing in the close tag </gpu_version>

Re: BOINC Future Drool - OpenCL enabling started for Ivy Bridge

Thanks for checking that. Not sure how a wrong tag for the GPU affects the functioning for CPU, but I'll be trying it out. There's no tag error warning as what we have for cc_config.xml... in a far future perhaps.:D

Where did you put the file? Think the most efficient way, since this is at app short name level [excellent not having to mess with version numbers]. One single file in the main data_dir would be great, it's user created, so not sure it should be in the projects folder where WCG controls what goes in and out.

edit: OK, insert the missing s, restarted client, fetched more CEP2, suspended all Ready to start with a max allowed of 1 and suspended a running task. Only 1 CEP2 would run, suspending more tasks caused cores to go idle. Unsuspending, immediately resumed the non-CEP2 tasks. Now determine the proper file placement and fix the wiki.

Re: BOINC Future Drool - OpenCL enabling started for Ivy Bridge

So, this is an excellent feature addition. You can have CEP2 run back to back by tweaking the number allowed "in progress" [in device profile], versus number to run [in app_info.xml]. There will always be a few at the top of the FIFO queue waiting for other CEP2 to complete. Hands free maximizing the clean energy contribution, without making the client inefficient or user impaired.
