UnverifiedBy copying CPU weight views to contiguous memory before H2D transfer, full model loading time was reduced from approximately 35 minutes to 6 minutes 20 seconds, achieving a 5.6× speedup.73% similarUnverifiedGPU HBM has the lowest access latency but limited capacity and the highest cost; CPU DRAM has larger capacity but access requires passing through the PCIe bus with significantly increased latency; the bandwidth gap between different tiers often reaches more than an order of magnitude.72% similarVerifiedModern CPU L1 cache access latency is approximately 0.5 nanoseconds, L2 approximately 4 nanoseconds, and a single main memory access requires 60–100 nanoseconds.70% similar
