"An example showing a grid computing system connecting many personal computers over the Internet using inter-process network communication ...
In computer science, inter-process communication (IPC) is the activity of sharing data across multiple and commonly specialized processes using communication protocols. Typically, applications using IPC are categorized as clients and servers, where the client requests data and the server responds to client requests."

"Grid computing is the collection of computer resources from multiple locations to reach a common goal. The grid can be thought of as a distributed system with non-interactive workloads that involve a large number of files. Grid computing is distinguished from conventional high performance computing systems such as cluster computing in that grid computers have each node set to perform a different task/ application. Grid computers also tend to be more heterogeneous and geographically dispersed (thus not physically coupled) than cluster computers." [Grid computing. Wikipedia]

"The C4ISR Architectural Framework (C4ISR AF) is now known as DoDAF, is a reference model developed by the US Department of Defense in the 1990s." [commons.wikimedia.org/ wiki/ Category:C4ISR_ Architecture_ Framework]
"The Department of Defense Architecture Framework (DoDAF) is an architecture framework for the United States Department of Defense (DoD) that provides visualization infrastructure for specific stakeholders concerns through viewpoints organized by various views. These views are artifacts for visualizing, understanding, and assimilating the broad scope and complexities of an architecture description through tabular, structural, behavioral, ontological, pictorial, temporal, graphical, probabilistic, or alternative conceptual means.
This Architecture Framework is especially suited to large systems with complex integration and interoperability challenges, and it is apparently unique in its employment of "operational views". These views offer overview and details aimed to specific stakeholders within their domain and in interaction with other domains in which the system will operate."

This circular arrows diagram example shows the Performance and Architecture Laboratory (PAL) circle. It was designed on the base of the diagram on the article "Advanced Computing, Mathematics and Data Division Research Highlights" webpage from the website of the Pacific Northwest National Laboratory of the U.S. Department of Energy.
"The Performance and Architecture Laboratory, or PAL, at Pacific Northwest National Laboratory (PNNL) takes on power and energy problems affecting high-performance computing (HPC), especially issues that may impact achieving practical performance at the exascale. Using methods that span processor architecture and system integration to software and programming models to performance and power modeling, PAL scientists, who are part of PNNL's HPC Group, have developed power-aware algorithms that use an accurate per-core proxy power sensor model to estimate the active power of each core. Their methods also have afforded the first workload-specific quantitative power modeling capability that accurately captures workload phases, their impact on power consumption, and the effects of system architecture and processor clock speeds."
