Cel mai puternic super-computer din Europa are procesoare AMD EPYC

In luna mai a acestui an, circulau zvonuri care spuneau ca AMD si Cray, un subsidiar expert in supercomputing pentru HP, lucreaza impreuna pentru a construi cel mai puternic super-computer din lume pentru Departamentul de Energie al Statelor Unite ale Americii. Astazi insa, se pare ca un alt guvern planuieste sa aiba un super-computer construit de cele doua companii.

Guvernul Marii Britanii a ales AMD si Cray pentru a le construi super-computerul ARCHER2, care va inlocui modelul ARCHER, situat in cadrul Universitatii din Edinburgh. Noul ARCHER 2 va fi de 11 ori mai puternic decat originalul, reprezentand un pas enorm pentru capacitatea comunitatii de stiinte din Marea Britanie.

Specificatiile tehnice ale lui ARCHER 2 sunt urmatoarele:

• A peak performance estimated at ~ 28 PFLOP/s
• System Design:
  • 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 workload manager
  • CrayPat as profiler
  • GDB4HPC as debugger

Noul super-computer va fi instalat in aceeasi incapere in care este in prezent ARCHER, astfel, oficialii se asteapta la o perioada de downtime cuprinsa intre 18 Februarie 2020 si 6 Mai 2020, cand ARCHER2 va fi operational. Dupa aceea, va fi o alta perioada de 30 de zile de teste de stres inainte ca noul sistem sa intre intr-un program normal de functionare.
