Deterministic performance of mmap
WebNov 23, 2024 · 1 mmap provides a way to map pages of memory. In Linux (among others), those pages of memory can have different backing devices: notably, files, and nothing at all (for anonymous mappings, MAP_ANONYMOUS ), or rather a swap device or file. WebIn a deterministic model, motion is seen as an unknown deterministic quantity. By maximizing the probability of the observed video sequence with respect to the unknown …

WebMar 1, 2024 · 1 Answer Sorted by: 4 Tmpfs is a file system which keeps all files in virtual memory. tmpfs lives completely in the page cache and on swap mmap copies file data to the disk cache when it needs the data to be in memory. With tmpfs, all the data is already in the disk cache (or swapped out). WebMar 22, 2012 · mmap() is not reading sequentially. what makes you think that? If you really access the mapped memory sequentially, the system will usually fetch the pages in that order. mmap() has to fetch from the disk itself same as read() does. sure, but the OS …
