LightDSA: Enabling Efficient DSA Through Hardware-Aware Transparent Optimization

Data streaming operations consume a significant portion of CPU resources in data centers. The Data Streaming Accelerator (DSA), integrated into modern Intel CPUs in datacenter, offers promising acceleration for these operations with user-friendly features. However, previous studies have overlooked DSA's internal mechanisms and the performance implications of these features, leaving key performance issues unresolved in real-world usage.
