tight coupling

tight coupling

[′tīt ′kəp·liŋ]

(electricity)

tight coupling

Hardware and software components that are linked together and dependent upon each other. For example, in a multiprocessing environment, where several computers share the workload, a tightly-coupled system might have to be shut down in order to add or replace one of the machines.

Software Tight Coupling
Tightly-coupled software means routines (modules, programs) that work in only one type of system and are dependent upon each other. For example, an operating system depends on its drivers to activate a peripheral device. Such drivers would require extensive programming changes to work in another environment. Contrast with loose coupling.

These are some common issues that challenge many HPC applications--especially tightly coupled and multi-threaded scientific codes.

Keeping "performance" in HPC; a look at the impact of virtualization and many-core processors

Because storage was embedded within tightly coupled and proprietary computing platforms, customers who wanted to pursue new storage applications had two options: live with what they had, or call the original vendor to develop yet another proprietary solution.

Thanks to standards, storage gets innovative

Integration with the MicroBlaze processor means CPU resources like the pipeline, processor register set and other processor resources become tightly coupled and shared with the FPU for optimum data bandwidth.

New Xilinx MicroBlaze soft processor increases clock frequency by 25 percent

The projectile GPS receiver was also designed with a number of adaptable features, including the ability to operate in a tightly coupled manner when integrated with an inertial-measurement unit, which allows the receiver to use adaptable narrowband tracking-loop techniques to aid in the suppression of jammers.

It represents a good example of how, in [the study of] condensed matter, physics and chemistry are tightly coupled.

These large, block-oriented, synchronous/semi-synchronous applications traditionally had to be tightly coupled directly to the processor owning the data.

Maintaining quality of service for WAN storage over IP

The SAN Volume Controller for Cisco MDS 9000 Solution has the same feature, function and interoperability as the appliance solution, with the advantage of being more tightly coupled and packaged inside the Cisco MDS 9000 switch instead of separately in the fabric.
