Bandwidth (computing) In computing, bandwidth is the maximum rate of data transfer across a given path. Bandwidth may be characterized as network bandwidth, [1] data bandwidth, [2] or digital bandwidth. [3][4] This definition of bandwidth is in contrast to the field of signal processing, wireless communications, modem data transmission, digital ...
Network programming traditionally covers different layers of OSI/ISO model (most of application-level programming belongs to L4 and up). The table below contains some examples of popular protocols belonging to different OSI/ISO layers, and popular APIs for them.
In digital computing and telecommunications, a unit of information is the capacity of some standard data storage system or communication channel, used to measure the capacities of other systems and channels. In information theory, units of information are also used to measure information contained in messages and the entropy of random variables ...
Message Passing Interface. The Message Passing Interface (MPI) is a standardized and portable message-passing standard designed to function on parallel computing architectures. [1] The MPI standard defines the syntax and semantics of library routines that are useful to a wide range of users writing portable message-passing programs in C, C++ ...
Cloud computing[1] is the on-demand availability of computer system resources, especially data storage (cloud storage) and computing power, without direct active management by the user. [2] Large clouds often have functions distributed over multiple locations, each of which is a data center.
CUDA. In computing, CUDA (originally Compute Unified Device Architecture) is a proprietary [1] parallel computing platform and application programming interface (API) that allows software to use certain types of graphics processing units (GPUs) for accelerated general-purpose processing, an approach called general-purpose computing on GPUs ...
Parallel computing. Large supercomputers such as IBM's Blue Gene/P are designed to heavily exploit parallelism. Parallel computing is a type of computation in which many calculations or processes are carried out simultaneously. [1] Large problems can often be divided into smaller ones, which can then be solved at the same time.
Chunking refers to strategies for improving performance by using special knowledge of a situation to aggregate related memory-allocation requests. For example, if it is known that a certain kind of object will typically be required in groups of eight, instead of allocating and freeing each object individually, making sixteen calls to the heap ...
