Semaphore is a hosted continuous integration and deployment service used for testing and deploying software projects hosted on GitHub and BitBucket. [1]While open source projects can use Semaphore for free in its full capacity, free use for private projects is limited to 100 builds per month (Semaphore Classic) or $20 of service every month (Semaphore 2.0).
Semaphore Corporation [1] was a company notable for being the first to provide public access to selected U.S. Postal Service databases, [2] and for its early computer publications in the 1980s. Founded in January 1982, the company operated for 35 years through September 2017.
In computer science, a semaphore is a variable or abstract data type used to control access to a common resource by multiple threads and avoid critical section problems in a concurrent system such as a multitasking operating system. Semaphores are a type of synchronization primitive. A trivial semaphore is a plain variable that is changed (for ...
The Open Container Initiative (OCI) is a Linux Foundation project, started in June 2015 by Docker, CoreOS, and the maintainers of appc (short for "App Container") to design open standards for operating system-level virtualization ().
A grid computing system that connects many personal computers over the Internet via inter-process network communication. In computer science, interprocess communication (IPC) is the sharing of data between running processes in a computer system.
A graphical user interface called EasyVZ was attempted in 2007, [9] but it did not progress beyond version 0.1. Up to version 3.4, Proxmox VE could be used as an OpenVZ-based server virtualization environment with a GUI, although later versions switched to LXC .
A process is a program in execution, and an integral part of any modern-day operating system (OS). The OS must allocate resources to processes, enable processes to share and exchange information, protect the resources of each process from other processes and enable synchronization among processes.
Hoare demonstrated their equivalence to semaphores. Monitors (and Concurrent Pascal) were soon used to structure process synchronization in the Solo operating system. [10] [11] Programming languages that have supported monitors include: Ada since Ada 95 (as protected objects) C# (and other languages that use the .NET Framework) Concurrent Euclid
