In computer science, multiple buffering is the use of more than one buffer to hold a block of data, so that a "reader" will see a complete (though perhaps old) version of the data instead of a partially updated version of the data being created by a "writer". It is very commonly used for computer display images.
Triple Buffering may result in a frame being discarded without being displayed if two or more newer frames are completely rendered in the time it takes for one frame to be sent to the display. By contrast, Direct3D swap chains are a strict first-in, first-out queue , so every frame that is drawn by the application will be displayed even if ...
The frequency of such pipeline stalls can be reduced by providing space for more than one item in the input buffer of that stage. Such a multiple-item buffer is usually implemented as a first-in, first-out queue. The upstream stage may still have to be halted when the queue gets full, but the frequency of those events will decrease as more ...
Circular buffering makes a good implementation strategy for a queue that has fixed maximum size. Should a maximum size be adopted for a queue, then a circular buffer is a completely ideal implementation; all queue operations are constant time. However, expanding a circular buffer requires shifting memory, which is comparatively costly.
Simultaneous multithreading (SMT): Issue multiple instructions from multiple threads in one cycle. The processor must be superscalar to do so. Chip-level multiprocessing (CMP or multicore): integrates two or more processors into one chip, each executing threads independently. Any combination of multithreaded/SMT/CMP.
If present in memory and not privately modified the physical page is shared with file cache or buffer. Shared memory acquired through shm_open. The tmpfs in-memory filesystem; written to swap when paged out. The file cache including; written to the underlying block storage (possibly going through the buffer, see below) when paged out.
This month, the Department of Transportation fined Jet Blue airlines $2 million for what it described as “multiple chronically late flights.” They penalized Frontier Airlines for the same reason .
The original TCP configurations supported TCP receive window size buffers of up to 65,535 (64 KiB - 1) bytes, which was adequate for slow links or links with small RTTs. Larger buffers are required by the high performance options described below. Buffering is used throughout high performance network systems to handle delays in the system.
