sleep number vs sleep science

the requested time has elapsed, or the number of seconds left to sleep, if the Call is interrupted by a signal handler, if we want it to sleep enough 5s, you can use a while loop to determine its return value. Note here is that the output of two times after the recv to continue to sleep is not necessarily the time, it

From the operating system's point of view, the OS maintains a ready queue (the queued thread of readiness). And at some point the CPU only serves the thread that is in the queue header in the ready queue.However, the thread that is currently being serviced may feel that the quality of the CPU service is not good enough, so quit early, which is yield.Or the thread that is currently being serviced needs to sleep for a while, wakes up and continues to be

Multithreading in Java is a preemptive mechanism, not a time-sharing mechanism. The preemption mechanism is that multiple threads are in a running state, but only one thread is running. Common Ground： 1. They are all in a multi-threaded environment, can block the specified number of milliseconds at the program's call, and return. 2. Wait () and sleep () can interrupt the paused state of the thread through

Sleep Sort SleepSort is a sorting algorithm that uses multiple threads for different sleep times. First look at the original version #!/bin/bashfunction f() { sleep "$1"echo "$1"}while [ -n "$1" ]do f "$1" shiftdonewait./sleepsort.bash 5 3 6 3 6 3 1 4 7 Pretty awesome. However, it seems difficult to understand Shell scripts. For example, I --!. In fact, the

The same point of sleep () and wait ():(1) in a multi-threaded environment, you can block the specified number of milliseconds at the call of the program and return(2) The interrupt () method interrupts the suspended state of the thread, causing the thread to throw interruptedexception immediately.The difference between sleep () and wait ():(1) The

goes to the uninterruptible sleep state, for example, if the NFS server is closed without amount the relevant directory beforehand. If the client executes DF, it will hang the entire session, and then use PS AXF to see if the DF process status bit has changed to D.In the case of a high load, it is possible to see if the uninterruptible sleep process is caused by vmstat, where column B of the procs portion

Windows batch files do not have a Linux-like sleep function for latency processing, there are 2 more practical ways to implement latency: 1, the use of wscirpt sleep function, precision 0.001 seconds Create a VBS delay file, and then invoke it in a batch file, using the WScript sleep function, to achieve the effect of sleep
