Whether loosely or tightly coupled, a system's performance is often reduced by message and parameter creation, transmission, translation (e.g. marshaling) and message interpretation (which might be a reference to a string, array or data structure), which require less overhead than creating a complicated message such as a SOAP message. Longer ...
Loose coupling is the opposite of tight coupling. ... Communication between loosely coupled components may be based on a flora of ... a non-profit organization ...
Loosely-coupled architectures feature high performances of each individual processor but do not enable for easy real-time balancing of the load among processors. Tightly-coupled architectures feature easy load-balancing and distribution among processors but suffer from the bottleneck consisting in the sharing of common resources through one or ...
MTC denotes high-performance computations comprising multiple distinct activities, coupled via file system operations. Tasks may be small or large, uniprocessor or multiprocessor, compute-intensive or data-intensive. The set of tasks may be static or dynamic, homogeneous or heterogeneous, loosely coupled or tightly coupled.
An example of the impact of Conway's Law can be found in the design of some organization websites. Nigel Bevan stated in a 1997 paper, regarding usability issues in websites: "Organizations often produce web sites with a content and structure which mirrors the internal concerns of the organization rather than the needs of the users of the site ...
Tightly coupled systems perform better and are physically smaller than loosely coupled systems, but have historically required greater initial investments and may depreciate rapidly; nodes in a loosely coupled system are usually inexpensive commodity computers and can be recycled as independent machines upon retirement from the cluster.
Very tightly coupled computer clusters are designed for work that may approach "supercomputing". "High-availability clusters" (also known as failover clusters, or HA clusters) improve the availability of the cluster approach. They operate by having redundant nodes, which are then used to provide service when system components fail.
Diagram of a symmetric multiprocessing system. Symmetric multiprocessing or shared-memory multiprocessing [1] (SMP) involves a multiprocessor computer hardware and software architecture where two or more identical processors are connected to a single, shared main memory, have full access to all input and output devices, and are controlled by a single operating system instance that treats all ...
