UnverifiedIn single-batch scenarios where batch size is 1, the arithmetic intensity of matrix multiplication drops significantly, memory bandwidth becomes the primary bottleneck, and the efficiency of traditional GPU architectures optimized for high throughput decreases markedly.74% similarUnverifiedThe workloads of coding agents are often bursty and uneven, making efficient scheduling under limited GPU resources a core challenge for scaling.72% similarUnverifiedSystem-bound means non-GPU factors such as CPU scheduling, PCIe transfer, and Python interpreter overhead become the bottleneck, requiring system-level measures such as asynchronous execution and reducing synchronization points.71% similarVerifiedIn high cache-hit-rate scenarios, blindly adding GPUs may yield little benefit; the bandwidth bottleneck should be identified before optimization.71% similarUnverifiedAfter training is complete, the actual number of effective line segments formed by the network is often far fewer than the theoretical maximum number of segments.71% similar
