Unverified50% confidenceFactExact time
When both the reading and writing sides of a pipe are in the same thread, the pipe degenerates into an inefficient memory-copy channel: data is written from user space into the kernel buffer and then copied from kernel space back to the same thread, which not only yields no concurrency benefit but also introduces system call overhead and the risk of blocking.

Unverified寄存器溢出（Register Spilling）会将溢出变量存入本地显存，引入额外全局显存访问导致性能倒退70% similarUnverifiedInput replay is a hidden trap: if the vendor re-bills the prompt on every continuation, a large system prompt will consume the money saved, so input and output tokens should be tracked separately.70% similarUnverifiedCombined with majority voting over redundant channels, even if a babbling node exists on one channel, the correct data from the other channel can still be adopted by the system, achieving end-to-end fault masking.69% similarUnverifiedThe cached input mechanism skips repeated inference computation by reusing the KV cache for identical prefix content, with cache-hit tokens billed at a lower price.69% similarUnverifiedAfter documents are extracted, vectorized, and fed to a large model, permission information may be stripped from the pipeline, leading to a real risk of data access leakage.68% similar
