Today the term "task" is used very ambiguously. For example, the Windows Task Manager manages (running) processes, while Windows Task Scheduler schedules programs to execute in future, what is traditionally known as a job scheduler, and uses the .job extension. By contrast, the term "task queue" is commonly used in the sense of "units of work".
When the active queue is empty the expired queue will become the active queue and vice versa. However, some enterprise Linux distributions such as SUSE Linux Enterprise Server replaced this scheduler with a backport of the O(1) scheduler (which was maintained by Alan Cox in his Linux 2.4-ac Kernel series) to the Linux 2.4 kernel used by the ...
Register (keyword), the hint in C and C++ for a variable to be placed in a register. Sethi–Ullman algorithm , an algorithm to produce the most efficient register allocation for evaluating a single expression when the number of registers required to evaluate the expression exceeds the number of available registers.
The size of a thread pool is the number of threads kept in reserve for executing tasks. It is usually a tunable parameter of the application, adjusted to optimize program performance. [ 3 ] Deciding the optimal thread pool size is crucial to optimize performance.
Queue overflow results from trying to add an element onto a full queue and queue underflow happens when trying to remove an element from an empty queue. A bounded queue is a queue limited to a fixed number of items. [1] There are several efficient implementations of FIFO queues.
Weighted round robin (WRR) is a network scheduler for data flows, but also used to schedule processes.. Weighted round robin [1] is a generalisation of round-robin scheduling. ...
In computer programming, a variable-length array (VLA), also called variable-sized or runtime-sized, is an array data structure whose length is determined at runtime, instead of at compile time. [1] In the language C , the VLA is said to have a variably modified data type that depends on a value (see Dependent type ).
For static-duration and automatic-duration variables, the size of the allocation must be compile-time constant (except for the case of variable-length automatic arrays [5]). If the required size is not known until run-time (for example, if data of arbitrary size is being read from the user or from a disk file), then using fixed-size data ...
