Abisko CPU Architecture

Understanding of the underlying architecture in Abisko is essential in obtaining optimal performance for all but trivial use cases.

Abisko is comprised of 318 compute nodes, each with 4 sockets of AMD Opteron 6238 (also known as Interlagos, Bulldozer core). They are clocked at 2.6GHz nominally, with overclock/TurboMode of up to 3.2GHz depending on how many cores are idle.

The 308 thin nodes have 128GB of DDR3-1600 RAM, the remaining 10 fat nodes have 512GB of DDR3-1066 RAM.
