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.
