Greetings. I've been lurking a long time. There is perhaps too much introduction here.
Why I've been lurking was related to OpenCL (and btrfs) issues related to some upgrading of hardware and software I have on my LAN when time permitted. Well, winter arrived and now there isn't quite so much stuff keeping me away from the computer. In the near future I will have 5 computers attached to 4 UPS, two of which will have Corsair digital power supplies. One computer will have a sort of deprecated AMD GPU, and the others will have newer hardware (mostly Polaris GPUs from AMD). Processors are all AMD. UPS software (NUT or proprietary) can provide estimates of how much power the UPS are providing. Lmsensors seems to have an ability to read GPU temperatures as well as CPU temperatures. SMART may give access to disk data, I am initially thinking that SSD aren't going to provide anything useful. And the Gnome libgtop2 library can provide access to CPU type process data. There is some code out there to get at data from Corsair digital power supplies. Some UPS software is sampling every 2 seconds, some every 15 or 30 seconds. What I am looking to do, is to sample a bunch of things at about the same rate and log it (on one machine). Sample the temperatures, sample the power levels and then look through the process statistics to find the N processes that are using more than 10% of any CPU (core). Much of what I am doing now, is public BOINC projects. And these BOINC projects may be interested in this from an energy budget point of view. I have some projects in mind, which a person might be able to do from a BOINC server. And I would like to be able to measure the energy budget on this. Einstein@Home seems to be one of the few BOINC projects which produces jobs for which Mesa3D is the OpenCL provider. I see SETI@Home sending jobs occasionally, but they don't compile as they assume Catalyst/fglrx because I have AMD GPUs. Maybe places like SETI@Home would be inclined to create OpenCL jobs, if there was software to measure energy budget? One could hope. At the moment, I am working in Perl. For getting at Corsair digital power supply data, spawning some program via the shell and capturing output should work for a start, but I probably should try to make a library and do things via XS. GTop has a Perl wrapper at CPAN, I don't think I've seen a Perl wrapper around anything lmsensors related. Too much introduction, I apologise. Are there aspects of GPU use; that Mesa3D provides, should provide or could provide? Especially with respect to OpenCL. Are there places/references where I can learn about this? No paywalled stuff please, I have no budget. If this means writing code (Mesa3D seems to be mostly C, I can do that, but most of my programming is number crunching in FORTRAN) to submit to Mesa3D, I can do that. Other things I should know? If I get something working, github is best place to put this? I think it might be useful at some point. Have a great day!
