The subsequent technology of purpose-built Azure HPC digital machines
Today, we’re excited to announce two new digital machines (VMs) that ship extra efficiency, value-adding innovation, and cost-effectiveness to each Azure HPC buyer. The all-new HX-series and HBv4-series VMs are coming quickly to the East US area, and thereafter to the South Central US, West US3, and West Europe areas. These new VMs are optimized for a wide range of HPC workloads comparable to computational fluid dynamics (CFD), finite ingredient evaluation, frontend and backend digital design automation (EDA), rendering, molecular dynamics, computational geoscience, climate simulation, AI inference, and monetary threat evaluation.
Innovative applied sciences to assist HPC prospects the place it issues most
HX and HBv4 VMs are full of new and progressive applied sciences that maximize efficiency and reduce complete HPC spend, together with:
- 4th Gen AMD EPYC™ processors (Preview, This fall 2022).
- Upcoming AMD EPYC processors, codenamed “Genoa-X,” (with basic availability in 1H 2023).
- 800 GB/s of DDR5 reminiscence bandwidth (STREAM TRIAD).
- 400 Gb/s NVIDIA Quantum-2 CX7 InfiniBand, the primary on the general public cloud.
- 80 Gb/s Azure Accelerated Networking.
- PCIe Gen4 NVMe SSDs delivering 12 GB/s (learn) and seven GB/s (write) of storage bandwidth.
Below are preliminary benchmarks from the preview of HBv4 and HX collection VMs utilizing 4th Gen AMD EPYC processors throughout a number of frequent HPC functions and domains. For comparability, efficiency data can also be included from Azure’s most up-to-date H-series (HBv3-series with Milan-X processors), in addition to a 4-year-old HPC-optimized server generally discovered in lots of on-premises datacenters (represented right here by Azure HC-series with Skylake processors).

HBv4-series brings efficiency leaps throughout a various set of HPC workloads
Azure HBv3 VMs with third Gen AMD EPYC™ processors with AMD 3D V-cache™ Technology already ship spectacular ranges of HPC efficiency, scaling MPI workloads as much as 27x greater than different clouds, surpassing lots of the main supercomputers on this planet, and providing the disruptive worth proposition of sooner time to answer with decrease complete value. Unsurprisingly, the response from prospects and companions has been phenomenal. With the introduction of HBv4 collection VMs, Azure is elevating the bar but once more—this time throughout an excellent better range of reminiscence performance-bound, compute-bound, and massively parallel workloads.

Updated technical specs for HBv4 will likely be posted at the moment.
HX-series powers subsequent technology silicon design
In Azure, we attempt to ship the very best platform for silicon design, each now and much into the longer term. Azure HBv3 VMs, that includes third Gen AMD EPYC processors with AMD 3D V-cache Technology, are a big step towards this goal, providing the very best efficiency and complete value effectiveness within the public cloud for small and medium reminiscence EDA workloads. With the introduction of HX-series VMs, Azure is enhancing its differentiation with a VM purpose-built for even bigger fashions turning into commonplace amongst chip designers concentrating on 3, 4, and 5 nanometer processes.
HX VMs will function 3x extra RAM than any prior H-series VM, as much as practically 60 GB of RAM per core, and constrained cores VM sizes to assist silicon design prospects maximize ROI of their per-core business licensing investments.

400 Gigabit InfiniBand for supercomputing prospects
HBv4 and HX VMs are Azure’s first to leverage 400 Gigabit NVIDIA Quantum-2 InfiniBand. This latest technology of InfiniBand brings better help for the offload of MPI collectives, enhanced congestion management, and enhanced adaptive routing capabilities. Using the brand new HBv4 or HX-series VMs and solely a normal Azure Virtual Machine Scale Set (VMSS), prospects can scale CPU-based MPI workloads past 50,000 cores per job.
Continuous enchancment for Azure HPC prospects
Microsoft and AMD share a imaginative and prescient for a brand new period of high-performance computing within the cloud: one outlined by fixed enhancements to the crucial analysis and enterprise workloads that matter most to our prospects. Azure continues to collaborate with AMD to make this imaginative and prescient a actuality by elevating the bar on the efficiency, scalability, and worth we ship with each launch of Azure H-series VMs.
