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 Quantum-2 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.
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.
