MQM8790-HS2F Technology
The QM8790 leverages NVIDIA's Scalable Hierarchical Aggregation and Reduction Protocol (SHARP) to offload collective communication operations directly within the switch silicon. This reduces latency and improves performance for HPC and AI workloads. It supports InfiniBand NDR (200G) and is backward compatible with EDR and HDR.
MQM8790-HS2F Working Principle
The switch processes data in transit using embedded hardware accelerators. Instead of routing data multiple times between endpoints, it aggregates and reduces data within the network, significantly cutting down communication overhead and improving overall cluster efficiency.
MQM8790-HS2F Application & Usage
Ideal for:
- High-Performance Computing (HPC) clusters
- Artificial Intelligence and machine learning training
- Hyperscale cloud data centers
- High-speed storage networks
- Research and academic supercomputing environments
