Cold without [email protected], GPU issues

Posted at age 28.

I realized the software for [email protected] was not set up since I reformatted, so I took care of that today. There was of course a small hurdle.

It’s been fairly cold lately in San Francisco, and I have used my space heater a few times lately. My room on Haight Street was usually quite warm, especially since my computer was always contributing to distributed computing research projects. Then it occurred to me to check if the FAHControl app was was even installed. It opened, so I apparently did incorporate that into my dotfiles setup scripts, but I noticed it was not processing a work unit and the profile said “Anonymous”.

This was not the first time I inadvertently stopped contibuting. In searching my email for the username and passkey, I found a chat with Walter from Saturday, August 6, 2016:

i just realized my room is so cold this week because i forgot to have my computer resume processing for [email protected] i paused it a week ago

Once I configured it with my information, it still did not seem to be working. I did a bit of searching and was delighted to see PS3EdOlkkola make a similar reference in a forum Re: “Empty work server assignment” - Linux GPU’s:

In Texas, it’s starting to get cool in the mornings. I’d rather turn on the heat by folding, not with HVAC ;)

I suspected there was a problem with the installation since my script installed the client via Homebrew Cask. The version installed seemed to be the most recent, though. I saw someone mention work units for single cores were not available at some point recently, and the fix was to specify more than one core. I configured mine for 4 as a test, but it still didn’t seem to work. I also tried to add a GPU core, but it did not automatically detect my GPU despite my having the NVIDIA CUDA drivers installed.

[/COLLAPSE]

Then I overwrote the /Library/Application Support/FAHClient/config.xml with the config from my backup before I formatted. That put it back how it was this morning (with the cores set to auto) as far as I can tell, but strangely it started working soon after.

Then I wanted to see about getting the GPU aspect working, but I ran into more problems. My macOS preference pane for the NVIDIA “web drivers” would not open.

Unable to open the NVIDIA Driver Manager.
Please try again or re-install the NVIDIA Web Driver package from the NVIDIA website.

It worked previously after reformatting, so I am not sure what change might have caused that to break. The prefrence pane for the CUDA info worked fine, and reported the driver version of the GPU web driver:

CUDA Driver Version: 8.0.83
GPU Driver Version: 10.17.34 (378.05.05.05f02)

I searched Google for the latest version of the web driver, but didn’t notice the top result was actually an older version. So I installed 10.17.34 (367.15.10.45f01), observed the preference pane still did not work, and then checked for the actual latest version. Confusingly, 378.05.05.15f01 was released a few weeks after the version I had, 378.05.05.05f02. I then noticed 378.05.05.15f01 was for macOS 10.12.5, which was recently released, and I was still on 10.12.4. I was not keen on upgrading, since accidentally upgrading previously caused me to need to reformat, but I took a chance and did it anyway. I spent all that time making my dotfiles for automatically setting up my computer, so I figured I might as well allow myself some peace knowing it would be easier to get back up and running in the worse case. Alas, upgrading to 10.12.5 and then the NVIDIA web driver to 378.05.05.05f01 still did not solve the problem.

For future reference, since I could not find it through NVIDIA’s driver search, the web drivers are apparently posted on this page and this feed.

It was only 11 a.m., but I had strangely been up since 7:30 and the day was indeed slipping away, so I gave up for now on trying to get [email protected] working on my GPU. I had no other apparent video problems (aside from a probably unrelated app freezing issue when videos are displayed, but I think that has to do with the CPU and encoding). Perhaps I will revisit this if the NVIDIA panel revives itself. At least I might have a slightly warmer room, now. :-)
