Is this an 8p Opteron 6200s?

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 yet?) and they are 4x2P "Each Cray XE6m blade includes four compute
nodes for high scalability in a small footprint... Each compute node is composed of two AMD Opteron processors (16-core), each coupled with its own memory and dedicated Gemini communication ASIC."

The "E" series is pretty much all CPU grunt, and the "K" series is hybrid utilizing many Tesla GPU's, so that board has to be an XE7/XE6, but I don't see the XE7 on the Cray website yet. I only see the XK7 which is not an 8 CPU board.

Page 3, which has the information quoted above and a picture of that board in the center.
They also support the 6300 series CPU's now as well.


EDIT2: Cray XE6m board





EDIT3: Cray XK7 board

Cray has their on custom fabric to replace the missing HT links between the two 4ps.

Cray had this for the 6100 series as well...
but there are no consumer boards for 8p G34...

OT but I thought the squiggles of thermal paste were question marks chop'd onto the picture at first :LOL:

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/
