Beskow

Beskow is a CRAY XC40 and is currently the fastest academic supercomputing system in Scandinavia.

PDC's main systems is called Beskow. It is a Cray XC40 system, based on Intel Haswell and Broadwell processors and Cray Aries interconnect technology. At PDC, we have a total of 11 racks in two rows with a theoretical peak performance of 2.43 petaflops. The system is named after the famous Swedish author and illustrator Elsa Beskow, who produced many delightful children's books.

Beskow is designed for running large parallel jobs, so time allocation applications for running wide jobs are preferred.

Beskow was ranked in 32nd position in the November 2014 Top 500 list.

The system went into full production and was available for SNIC allocations from January 2015. Beskow was then upgraded from 9 to 11 racks in September 2017. The intended lifetime of the system is 5 years, that is, until the 31st of December 2019.
