Hell yeah! I went 10 months on the 8P without a UPS (or two since it would need two haha). 850W may not be as high as some of these overclocked 6180SE machines, but it still turns the meter!
I would not waste your time with that Folding Forum thread. They kept telling bowlinra to contact the author of langouste, who had responded in thread haha. I am surprised that they don't know tear by now.
It is Four 2P's, as per the brochure. Each 2P has a Gemini communication ASIC module. It is not the same as HT, it uses MPI between the nodes. It is similar to infiniband but proprietary.Cray favors OpenMP in their brochures for clustering: http://openmp.org/wp/
If I am not mistaken, it is 4 x 2P with a proprietary interconnect between them. I have no idea if they function as one 8P or 4 x 2P's. That all depends on what cray did. They also used this on the Cray XK6/XE6.
EDIT: Yeah, that is probably an XE6 / XE6m board (or maybe XE7 which is not out...
If you upgrade to 4x 2.4Ghz hexacores, your PPD on smp will go up to about 70K PPD, but more importantly, you will be able to do 8101 bigadv. Your PPD on 8101 with 4 x 2.4Ghz hexacores would be about 123K PPD.
I am basing this off of TPF's from my 8P socket F loaded with 8 x 8431 2.4Ghz...
