Beskow
Beskow was PDC's flagship system from 2015 to 2020. It was a CRAY XC40 and was one of the fastest academic supercomputing systems in Scandinavia while in operation.
Beskow was a Cray XC40 system based on Intel Haswell and Broadwell processors and Cray Aries interconnect technology. The final version of the Beskow system at PDC had a total of 11 racks in two rows with a theoretical peak performance of 2.43 petaflops. The system was named after the famous Swedish author and illustrator Elsa Beskow , who produced many delightful children's books.
Beskow was designed for running large parallel jobs and was ranked in 33rd 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 was initially for 5 years (until the 31st of December 2019), although that was extended so the system would be available till at least the end of 2020.
System
- 11 cabinets = 515 blades = 2,060 compute nodes
- 2 x Intel CPUs per node:
9 of the cabinets have Xeon E5-2698v3 Haswell 2.3 GHz CPUs (16 cores per CPU)
2 of the cabinets have Xeon E5-2695v4 Broadwell 2.1 GHz CPUs (18 cores per CPU) - 67,456 cores in total
- High speed network Cray Aries (Dragonfly topology)
Performance
- Peak performance 2.438 PFLOPS
- LINPACK performance 1.80 PFLOPS
- 156.4 TB primary memory (64 GB per node on the Haswell nodes and 128 GB per node on the Broadwell nodes)
- 5 PB Lustre file system
Usage
- was available for academic research via SNIC and PRACE
- was used for a variety of industrial research projects (including collaboration with Scania)
