I just fried another GPU. Mostly from years of mfaktc. I gave them the summer off during the heat wave except for poly select. It was just enough to push it over the thermal limits I guess. I will have to time-share my remaining GPU with my other projects.

Is there an ETA for when the poly select server is going online? Perhaps someone else could host it thinking there won't be a large database associated with this phase.

I don't have an office yet at work; I expect that all to be resolved next week. It's possible I could be ready to host a poly select server roughly 1 Oct.

It appears that Greg will do this via SNFS
