a) Not sure if anybody was having this issue as well, but apparently my cpu:10 slot was having problems picking up a WU since the-day-before-yesterday, hence the slight drop off in PPD. (Fixed that by closing and ending the process and then starting it back up again.)
Was trying to run the system in a near headless state and letting it do its thing. Didn't catch that it was having problems with it until a couple of hours ago - was probably like that for about a day-and-a-half.
b) I'll likely drop off again once this/competition is over. CPU based systems just simply can't compete with the new GPU hardware (still struggling to justify getting 6 Teslas because I don't run enough FEAs for that, and even then, at 2x-3x improvement, not quite nearly substantial enough yet to warrant doing that), especially when a CPU-based system would be of vastly greater use for me for all the other stuff that I normally do. (And having 6 GTX1080s would be nice for F@H, but that's all that I would have use for, which again, makes it a tough sale (to the wife).)
c) The systems will likely have to return to running CFD/FEAs for me so that I can make money with those systems which will enable me to buy new/more toys. My current CFD that's running is estimated to take a total of 75 DAYS(!) (running continuously, 24/7). (External aerodynamics for a full semi/tractor-trailer/18-wheeler, 7.2 million elements/cells, 20,000 timesteps, DES). And this is my "small" case. Each result file is just shy of 1 GB, and I had to restart it a couple of times to write LESS data (because if I wrote it all to disk, it would consume almost 20 TB.) So, the other two systems would have to go back to CFD research for me.
d) Not sure if the GPU power calculations above includes the power for the supporting/host system or if that's the GPU only. My electricity bill is already pushing close to $300/month, so...it's a difficult sale.
