more preliminary results:
following the failed p2675 WU, I've gone ahead and started up a 4-core A1 and an 8-core A2.
load averages are 8.86, 9.12, 9.21
(albeit I was just doing a bit of reading into that and it doesn't seem like that it actually describes the full picture, but I can do more checking around on this to see if it makes sense or if it's a good/bad thing.)
In any case, here's what I've been able to find out so far.
For p2671 r20 c22 g69
It took 8 hours for it to run it.
While yes, I agree that I can't really compare different projects, but here's what I think is happening (based on the PPD calculations).
The initial calculations/estimates for the PPD with p2671 r20 c22 g69 was between 5760-5800. That would make sense given that that WU was credited as 1920 points, and at approximately 8 hours per WU (of that project), 5760 would be a perfect match for it. (3*1920 = 5760.)
However, now, the A2 core is running p2669 r16 c136 g56 (credit: 1920 points) but it's reporting the PPD to be 3645.89. That would mean that based on the PPD numbers, I'd only be able to work on approximately 1.9 p2669 WUs per day.
The A1 core however is running p5101 r0 c157 g55 (credit: 2165 points), but that's reporting the PPD to be 1028.35. By that calculation, it looks like that it would take approximately 2.1 days per p5101 WU.
Total est. PPD running it this way: 4674.24
Ergo, current preliminary results would point this being a bad idea. (Yes yes, I know. Some people here are prolly going to be like..."duh?" BUT...here's the numbers that may be able to prove it). However, this is only with one 4+8-core WUs for now, (hence why it's preliminary). We will need to wait and see a bit more to see if this pattern continues.
NOTE: As many of you have also said -- the A1 core is known to be slower in PPD. So, perhaps the real test would be when my system is running with two A2 cores and see how that fairs.
It is still possible that HTT will be bad...even on all current Q9-series and Core i7s. (WU slowdown. Possibly minimal impact on total overall PPD).
Testing still contiues. Will report back with more info once I get it.
