UnverifiedBy routing inter-GPU data exchange through NVLink and bypassing the host PCIe channel, reliance on host bandwidth in inference scenarios can be reduced.78% similarUnverifiedTraditional GPU servers need to transfer data across hundreds to thousands of chips via high-speed interconnect protocols such as NVLink and InfiniBand, which consumes significant bandwidth and introduces latency and additional power consumption.76% similarUnverifiedTensor Parallelism horizontally shards the weight matrices of individual layers across multiple GPUs and aggregates results via AllReduce communication; it has lower latency but places extremely high demands on inter-GPU interconnect bandwidth (such as NVLink).75% similarUnverifiedTensor parallelism requires extremely low-latency all-reduce operations and has the strongest dependency on NVLink bandwidth.71% similarUnverifiedConsumer-grade GPUs are inferior to data center cards in memory bandwidth, NVLink interconnect capability, and long-term full-load stability, making them more suitable for inference deployment than large-scale distributed training.70% similar
