line compound

In classical computer technology, the term "performance network" was used to describe the combination of several computers. With such an interconnected system, computing operations can be performed simultaneously by several processing computers, which can also be spatially separated from each other. The approach is comparable to a multiprocessor system at the network level.

In a performance network, components that functionally cooperate and are implemented in different computer systems can work together in a system-technical framework and jointly access resources to solve a problem. For this purpose, new operating system constructs, in particular, must be used in addition to data communication technology resources.

However, the class of problems suitable for this type of distributed processing is limited. Due to restrictions on the maximum achievable parallelism when decomposing the problem into individual processing kernels, in most cases the processing time does not fall to the same extent as the number of computationally capable components increases. Also, additional administrative work has to be done.
