Unverifiedext4's block group mechanism divides a disk partition into several regions, each block group is typically 128 MB, and the Orlov block allocation algorithm is used for directory allocation.74% similarPartially VerifiedA standard FP32 model occupies 4 bytes per parameter, while INT4 quantization compresses this to 0.5 bytes, theoretically achieving an 8x memory saving.70% similarUnverified位置编码外推方案可将模型有效上下文从最初的4K、8K扩展至128K乃至百万级token69% similarUnverified差分启发式需要O(K×N)的存储空间（K个地标、N个节点），例如100万节点的图使用16个地标、每个距离值4字节存储，总内存约64MB68% similarUnverifiedReal mode uses 16-bit registers and a segmented memory model, calculating a 20-bit physical address by shifting the 16-bit segment register left by 4 bits and adding a 16-bit offset, with an addressable space of only 1MB.68% similar
