AMD will power the UK’s ARCHER2 Supercomputer – A massive win for EPYC

UK Research and Innovation (UKRI), the quasi-autonomous non-governmental organisation (QuANGO) that directs UK research funding, has announced that AMD will power the UK ARCHER2 Supercomputer using EPYC processors. 

The system will feature 5,848 compute nodes, 748,544 total CPU cores and feature a total of 1.57 petabytes of combined system memory. This gives each node access to128 Zen 2 CPU cores over two 64-core AMD ROME processors at 2.2GHz. This means that AMD has just sold almost 12,000 flagship-quality EPYC processors to a single user. 

The UK’s ARCHER 2 supercomputer will be built by Cray and be deployed at the University of Edinburgh, offering an estimated 28 PFLOPs of peak performance. The system is due to be put into service in May 2020. On May 6th, a period of 30 days of continuous operation will be scheduled to stress-test the system to help resolve any and all issues before the Supercomputer enters full service. The original ARCHER Supercomputer will end its operations on February 18th 2020, after which the UK’s ARCHER 2 system will be installed. 

Right now, it is estimated that the ARCHER 2 will be able to offer an 8.7x performance boost for CP2K workloads, 9.5x gains for OpenSBLI, 11.3x enhancements for CASTEP, 12.9x boosts for GROMACS, and 18.0x improvements for HadGEM3.

Below are the specifications of the UK’s ARCHER2 supercomputer. 

Hardware specifications:

– 28 PFLOP/s peak performance
– 5,848 compute nodes, each with dual AMD Rome 64 core CPUs at 2.2GHz, for 748,544 cores in total and 1.57 PBytes of total system memory
– 23x Shasta Mountain direct liquid cooled cabinets
– 14.5 PBytes of Lustre work storage in 4 file systems
– 1.1 PByte all-flash Lustre BurstBuffer file system
– 1+1 PByte home file system in Disaster Recovery configuration using NetApp FAS8200
– Cray next-generation Slingshot 100Gbps network in a diameter-three dragonfly topology, consisting of 46 compute groups, 1 I/O group and 1 Service group
– Shasta River racks for management and post processing
– Test and Development System (TDS) platform, to be installed in advance
– Collaboration platform with 4 x compute nodes attached to 16 x Next Generation AMD GPUs

Software stack:

– Cray Programming Environment including optimizing compilers and libraries for the AMD Rome CPU
– Cray Linux Environment optimized for the AMD CPU blade based on SLES 15
– Shasta Software Stack
– SLURM work load manager
– CrayPat as profiler
– GDB4HPC as debugger

AMD will power the UK's ARCHER2 Supercomputer - A huge win for EPYC  

The UK’s ARCHER2 Supercomputer is estimated to cost £79 million. This may be the first of many new Supercomputing design wins for AMD.
