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.

This machine has 2 AMD six-core Opteron 8431, 2.4 GHz, 32 GB shared memory, 250 GB disk. It has a nVidia GeForce GTX 285, and an ATI Radeon HD 5800 card. You can test Nvidia with CUDA or OpenCL, and ATI Stream GPU with OpenCL.
Loading cuda toolkit:
hamrinsberget [~]$ module load cudatoolkit
You load this, if you want to run CUDA on the Nvidia card.
