In computing system generation or sysgen is the process of creating a particular unique instance of an operating system by combining user-specified options and parameters with manufacturer-supplied general-purpose program code to produce an operating system tailored for a particular hardware and software environment.
Full generation of the operating system. Generation of compilers and associated libraries. Updating of the I/O configuration; For MVT (either TYPE=MVT or TYPE=M65MP) with TSO, the TSOGEN macro plays the same role as GENERATE. Either macros analyzes the options specified on the previous macro calls and punches the Stage 2 job stream.
Ninja – Free build automation software; Perforce Jam – Build tool by Perforce, inspired by Make; Qt Build System – cross-platform free and open-source software for managing the build process of software; Rake – Make-like tool written in Ruby
In software engineering, a software development process or software development life cycle (SDLC) is a process of planning and managing software development. It typically involves dividing software development work into smaller, parallel, or sequential steps or sub-processes to improve design and/or product management .
To generate software interrupts in Unix-like operating systems, the kill(pid,signum) system call will send a signal to another process. [ 63 ] pid is the process identifier of the receiving process. signum is the signal number (in mnemonic format) [ b ] to be sent.
The operating system keeps its processes separate and allocates the resources they need, so that they are less likely to interfere with each other and cause system failures (e.g., deadlock or thrashing). The operating system may also provide mechanisms for inter-process communication to enable processes to interact in safe and predictable ways.
As computers became faster the setup and takedown time became a larger percentage of available computer time. Programs called monitors, the forerunners of operating systems, were developed which could process a series, or "batch", of programs, often from magnetic tape prepared offline. The monitor would be loaded into the computer and run the ...
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.
