AI Technical Summary
The performance of modern inter-GPU communication is limited by the overhead of data synchronization. Especially in collective communication operations, software-level flag polling and memory barriers lead to wasted computing resources and latency. Although the LL128 protocol improves bandwidth utilization, the synchronization overhead is still relatively large.
The data synchronization and retry mechanism of the LL128 protocol is implemented in hardware. Flag detection and synchronization operations are achieved through a data synchronization device, including instruction parsing, memory access control, flag detection and comparison, and data writing unit. Hardware circuitry is used to achieve nanosecond-level response.
It frees up computing resources, improves communication efficiency, reduces latency, and enhances the scalability of computing systems in large-scale cluster environments.
