Introduction

PDC Cray XE6

Eight of the 16 racks of PDC's supercomputer Lindgren

Lindgren is a Cray XE6 system, based on AMD Opteron 12-core “Magny-Cours” (2.1 GHz) processors and Cray Gemini interconnect technology. At PDC, we have 16 racks with a theoretical peak performance of 305 teraflops. Lindgren is ranked in 31st place among the 500 most powerful computer systems in the world (Top500, June 2011). Our Cray system is named after the prolific and talented Swedish author Astrid Lindgren, who wrote many delightful children's books.

Lindgren is designed for running large parallel jobs. Therefore, all users with time allocations on Lindgren must run jobs that use an average of at least 512 cores. This is a definite lower limit which is likely to be increased in the future (for instance, to 1024 cores).
