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™ Expertise already ship spectacular ranges of HPC efficiency, scaling MPI workloads as much as 27x greater than different clouds, surpassing most of the main supercomputers on the earth, and providing the disruptive worth proposition of quicker time to resolution with decrease whole 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 a fair higher variety of reminiscence performance-bound, compute-bound, and massively parallel workloads.

Notes: 1) “r” denotes assist for distant direct reminiscence entry (RDMA) and “s” denotes assist for Premium SSD disks. 2) At Basic Availability, Azure HBv4 VMs will probably be upgraded to Genao-X processors that includes 3D V-cache. Up to date technical specs for HBv4 will probably be posted at the moment.

HX-series powers subsequent era silicon design

In Azure, we try to ship the most effective 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 Expertise, are a major step towards this goal, providing the very best efficiency and whole 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 focusing on three, Four, and 5 nanometer processes.

HX VMs will characteristic 3x extra RAM than any prior H-series VM, as much as almost 60 GB of RAM per core, and constrained cores VM sizes to assist silicon design prospects maximize ROI of their per-core industrial 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 era of InfiniBand brings higher assist for the offload of MPI collectives, enhanced congestion management, and enhanced adaptive routing capabilities. Utilizing the brand new HBv4 or HX-series VMs and solely a typical Azure Digital Machine Scale Set (VMSS), prospects can scale CPU-based MPI workloads past 50,000 cores per job.

Steady 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.
