Enhancing HPC and AI Supercomputers and Applications

Accelerated In-Network Computing

Today’s high-performance computing (HPC), AI, and hyperscale infrastructures require faster interconnects and more intelligent networks to analyze data and run complex simulations with greater speed and efficiency. NVIDIA InfiniBand enhances and extends its In-Network Computing with preconfigured and programmable compute engines, such as the third generation of NVIDIA Scalable Hierarchical Aggregation and Reduction Protocol (SHARPv3)™, Message Passing Interface (MPI) Tag Matching, MPI All-to-All, and programmable engines, delivering the best cost per node and ROI.

 
Benefits of Performance Isolation

Performance Isolation

The NVIDIA Quantum-2 InfiniBand platform provides innovative proactive monitoring and congestion management to deliver traffic isolations, nearly eliminating performance jitter, and ensuring predictive performance as if the application is being run on a dedicated system.

Cloud-Native Supercomputing

The NVIDIA Cloud-Native Supercomputing platform leverages the NVIDIA® BlueField® data processing unit (DPU) architecture with high-speed, low-latency NVIDIA Quantum-2 InfiniBand networking. The solution delivers bare-metal performance, user management and isolation, data protection, on-demand high performance computing (HPC), and AI services—simply and securely.
