The von Neumann architecture —also known as the von Neumann model or Princeton architecture —is a computer architecture based on a 1945 description by John von Neumann, and by others, in the First Draft of a Report on the EDVAC. [1] The document describes a design architecture for an electronic digital computer with these components: The ...
Bottleneck (software) In software engineering, a bottleneck occurs when the capacity of an application or a computer system is limited by a single component, like the neck of a bottle slowing down the overall water flow. The bottleneck has the lowest throughput of all parts of the transaction path. System designers try to avoid bottlenecks ...
Early 1980s–1990s: Lessons of RISC. In the early 1980s, researchers at UC Berkeley and IBM both discovered that most computer language compilers and interpreters used only a small subset of the instructions of complex instruction set computing (CISC). Much of the power of the CPU was being ignored in real-world use.
Performance tuning. Performance tuning is the improvement of system performance. Typically in computer systems, the motivation for such activity is called a performance problem, which can be either real or anticipated. Most systems will respond to increased load with some degree of decreasing performance. A system's ability to accept higher ...
Stored-program computer. A stored-program computer is a computer that stores program instructions in electronically or optically accessible memory. [1] This contrasts with systems that stored the program instructions with plugboards or similar mechanisms. The definition is often extended with the requirement that the treatment of programs and ...
The bottleneck is the minimum residual capacity of all the edges in a given augmenting path. See example explained in the "Example" section of this article. The flow network is at maximum flow if and only if it has a bottleneck with a value equal to zero. If any augmenting path exists, its bottleneck weight will be greater than 0.
Bottleneck (engineering) This graphic shows the bottleneck that can arise between the CPU, memory controller, and peripherals. In engineering, a bottleneck is a phenomenon by which the performance or capacity of an entire system is severely limited by a single component. The component is sometimes called a bottleneck point.
Clustal is a computer program used for multiple sequence alignment in bioinformatics. [2] The software and its algorithms have gone through several iterations, with ClustalΩ (Omega) being the latest version as of 2011. It is available as standalone software, via a web interface, and through a server hosted by the European Bioinformatics ...
