Memory sorting is the process of optimizing memory requests for faster processing. It can be easily done on a single CPU system but may cause problems on multiple CPUs. Without it, tasks would be slower and programmers would have to write more code.
Memory sorting, or reordering, is a process by which the central processing unit (CPU) takes the computer’s memory requests and sorts them according to the most optimized pattern. Process changes requests, often processes are completed out of order, but users and programmers do not see this. This can usually be done very easily on a single CPU system, but a multiple CPU system may experience a problem when ordering. If this process weren’t used, computers wouldn’t be as efficient at completing user requests.
Whenever someone does something on a computer, such as moving the mouse, opening a program, or editing an image, the CPU has to approve memory usage for the task. These requests usually arrive in a linear fashion, but are rarely processed this way. With memory sorting, tasks are processed in the best possible way to make your computer run faster. For example, if the CPU can easily deal with the second process before the first, it will use up memory for that process before moving on to others.
Requests often run out of order, which can confuse users and programmers. At the same time, the CPU is hardwired to know that memory ordering can confuse them, so it runs everything in a way that makes processes appear to complete linearly, even though they aren’t. This makes it easier for users to understand and usually prevents programmers from having to enter excessive code to ensure that the CPU works efficiently.
Memory sorting can normally be done easily on a computer with a single CPU, but there may be problems with a computer that has multiple CPUs. This is because it is easier to properly approve and order memory accesses with one CPU, but two or more CPUs may falter when trying to process multiple tasks. If there is adequate communication between the two or more CPUs, this problem is usually mitigated.
Without memory sorting, tasks could be more difficult for the computer and the programmer. On the computer side, the CPU would only be able to service requests as they came in, meaning that the whole process slows down and might make users wait. For the programmer, he would have to write excessive code to ensure that the CPU takes care of all tasks properly, which would make the program creation much longer.
