Unverifiedcache-fit means that all of the model's weights reside permanently in L3 cache, so that each forward pass reads the weights from cache, thereby bypassing DRAM's bandwidth bottleneck and access latency.70% similarUnverifiedDouble buffering refers to the same data page existing simultaneously in both the OS page cache and shared buffers, resulting in duplicated memory usage and dilution of effective cache capacity.69% similarUnverifiedO_DIRECT is a Linux file open flag that bypasses the page cache and transfers data directly from disk to user-space buffers, letting a program fully control memory usage and avoid double-copy overhead.67% similarUnverifiedPagedAttention causes KV cache memory waste to occur only in the last unfilled block of a request, and vLLM reports waste of less than 4%.65% similarUnverifiedRing buffer logging is common in the Linux kernel (dmesg), where logs are continuously written to a fixed-size in-memory ring area and only flushed to disk when a specific condition is triggered.62% similar
