The documentation of perf is not very detailed (as of 2014); for example, it does not document most events or explain their aliases (often external tools are used to get names and codes of events [15]). [16] Perf tools also cannot profile based on true wall-clock time., [16] something that has been addressed by the addition of off-CPU profiling.

The Slurm Workload Manager, formerly known as Simple Linux Utility for Resource Management (SLURM), or simply Slurm, is a free and open-source job scheduler for Linux and Unix-like kernels, used by many of the world's supercomputers and computer clusters. It provides three key functions:
Pip's command-line interface allows the install of Python software packages by issuing a command: pip install some-package-name. Users can also remove the package by issuing a command: pip uninstall some-package-name. pip has a feature to manage full lists of packages and corresponding version numbers, possible through a "requirements" file.

The sense of "process" (or task) is "something that takes up time", as opposed to "memory", which is "something that takes up space". [b] The above description applies to both processes managed by an operating system, and processes as defined by process calculi. If a process requests something for which it must wait, it will be blocked.
The renderer system is what makes it possible to represent Salt's configuration management data in any serializable format. [ 10 ] Returners : the remote execution calls made by Salt are detached from the calling system; this allows the return information generated by the remote execution to be returned to an arbitrary location.
There are four principal events that cause a process to be created: System initialization. Execution of process creation system call by a running process. A user request to create a new process. Initiation of a batch job. When an operating system is booted, several essential processes are typically initiated to prepare the system for operation.
The program counter (PC), [1] commonly called the instruction pointer (IP) in Intel x86 and Itanium microprocessors, and sometimes called the instruction address register (IAR), [2] [1] the instruction counter, [3] or just part of the instruction sequencer, [4] is a processor register that indicates where a computer is in its program sequence.
