When I was testing how the number of threads affects speed, I encountered a very strange behavior. With one thread the time is about 2s, with two the time is 10s!!!! And when adding more threads the time decreases (with 32 threads the time is about 4s). I was running the code on a virtual machine with 4 cores. I didn't use any mutexes and sleep() functions. What is the reason for that?

If the workload is very small then the overhead of creating and waiting for threads plays a much bigger role. After 4 threads you shouldn't see much of a performance improvement. Do you have the exact time it take to execute for each number of threads you tested? Also, can you share the code you're trying to execute? Thanks

I know parallel used multiple core and thread is only one core But I have question what is task What is multiplthreds

Threads have different meanings based on which part of the computer you're looking at. A thread in the hardware is the number of cores the OS sees. (So if you have a 4 core 8 thread CPU, the OS sees that you actually have 8 cores and you can run 8 processes in parallel). A thread in software is just another line of execution for a process A task is usually a program that is executed completely on one single thread

@@CodeVault Thank you bro but I have the same issue I can’t understand If we say parallel just use core okay “ And thread is one core with the same program running okay “ task is thread like events in the same program run? And why some people say multiplethread it’s seems to me it’s threads ? Can you draw that in future videos please And sorry for my bad English

Would your definition still hold true when there are multiple CPUs?
@CodeVault 2 жыл бұрын
Yes, of course. Multiple CPUs on the same system acts much like one large CPU

But I realized that Parallelism is more effective
@CodeVault 3 жыл бұрын
Yes, ideally you want your program to run in parallel without any concurrency (or as little as possible)
