CPU time (or process time) is the amount of time that a central processing unit (CPU) was used for processing instructions of a computer program or operating...

GNU time) or as a shell builtin in most cases (e.g. in sh, bash, tcsh or in zsh). The total CPU time is the combination of the amount of time the CPU or...

minimize wasting CPU time by avoiding unnecessary task switching. In typical designs, a task has three states: Running (executing on the CPU); Ready (ready...

a utility or shell script with a particular CPU priority, thus giving the process more or less CPU time than other processes. A niceness of -20 is the...

certain amount of processing time on the CPU. If the CPU has completed all tasks it is idle. Modern processors use idle time to save power. Common methods...

A CPU cache is a hardware cache used by the central processing unit (CPU) of a computer to reduce the average cost (time or energy) to access data from...

processing unit (CPU). A scheduler may aim at one or more goals, for example: maximizing throughput (the total amount of work completed per time unit); minimizing...

the time at which a task finishes and the time at which the task started. Wall time is thus different from CPU time, which measures only the time during...

applications, deciding when they will receive central processing unit (CPU) time or space in memory. On modern personal computers, users often want to...

round-robin scheduler generally employs time-sharing, giving each job a time slot or quantum (its allowance of CPU time), and interrupting the job if it is...

implementation of CPUs have changed over time, but their fundamental operation remains almost unchanged. Principal components of a CPU include the arithmetic–logic...

CPU shielding is a practice where on a multiprocessor system or on a CPU with multiple cores, real-time tasks can run on one CPU or core while non-real-time...

thread leaving its CPU, another thread can always be found to run on that CPU, even if it is only the CPU's idle thread. The CPU time attributed to the...

The CPU time spent on finding these factors amounted to approximately 900 core-years on a 2.1 GHz Intel Xeon Gold 6130 CPU. Compared to the...

computer science, a task, job or process is said to be CPU-bound (or compute-bound) when the time it takes for it to complete is determined principally...

system time is process time, which is a count of the total CPU time consumed by an executing process. It may be split into user and system CPU time, representing...

A CPU card is a printed circuit board (PCB) that contains the central processing unit (CPU) of a computer. CPU cards are specified by CPU clock frequency...
