HB-series, designed to provide supercomputer-grade performance and scalability with the best price performance on the public cloud, are now generally available in South Central US and Western Europe.

A single HB VM will perform 2-3 times faster than the servers that most HPC customers have in their on-premises data centres today. Customers can also run MPI-based HPC applications across up to 300 VMs and 18,000 CPU cores

HB-series VMs are optimised for HPC applications driven by memory bandwidth, such as fluid dynamics, explicit finite element analysis and weather modelling. HB VMs feature 60 AMD EPYC 7551 processor cores, more than 260 GB/s of memory bandwidth, 4 GB of RAM per CPU core, no hyperthreading, 700 GB of local NVMe storage and up to 4 Managed Disks.

HB VMs are interconnected by 100 Gb EDR InfiniBand, support OFED drivers and all RDMA verbs, and utilise Mellanox ConnectX-5 NICs featuring hardware acceleration for MPI collectives. On HB VMs, customers can realise MPI latencies up to 10 times lower than networking options found elsewhere on the public cloud.

Optionally, HB-series VMs can connect to a Cray ClusterStor in Azure storage system for ultra high-performance storage needs.
