Out of Order

Authorities in university dormitories are used to prohibit the use of certain things (fountains, bathrooms, kitchen etc) for a long time.

This is usually a kind of punishment imposed by authoritative officials in the dormitory to teach students a lesson.

The outcome of this strategy is varied and the extreme situation is that it leads to riots and any confusion.

After someone vomited with the fountain on the second floor - after cleaning and obvious operation - it was deemed "broken"

Melt strength is a side effect caused by "chaotic execution". Out-of-order execution is a technique used to speed up execution by new processors scheduling operations in advance and running them out-of-order, resulting in a name. Of course, this has its own side effects. Depending on the timing differences between execution units, information on the nature of the program may be leaked. In addition, data from untrusted sources can be loaded into the temporary cache of vulnerable CPUs, and the CPU can use it to perform further calculations.

Decades ago, before the invention was executed out of order, the CPU was what we called "sequential" design today. Instructions executed in the order received do not attempt to sort or execute them more efficiently. One of the main problems with ordered execution is that the pipe stall causes the entire CPU to stop until the problem is resolved. Another problem facing the development of speculative execution is the speed difference between CPU and main memory. The figure below shows the difference between CPU and memory clock. As the gap gets wider, the time it takes for the CPU to wait for the information to be delivered to main memory is increasing. Features such as L1, L2, L3 caches and speculative execution are designed to keep the CPU busy and minimize idle time.

• Oh no, the copy machine has broken down. • Sit down with Mr. Phillips! You have a problem. • Some pages are messed up. • Finally he called the operator and asked if the phone failed. • Father, something has happened here. • The campaign speech ended. • The toilet is almost always out of order. • All phones I tried failed. • A suffocating woman was in trouble.

If a machine or equipment fails, the phone will not function properly. b) Unofficial British English WONG / UNSUITABLE, if someone's action fails, it is unacceptable. SYN US English c) Incorrect / inappropriate violation of the Committee, Court, Congress, etc. Registered in daily English, people frequently say that machines and devices are not working properly, broken rather than broken: the phone is not working properly. → Order
