The 'runtime' Package
Explore how Go's runtime package enables control over CPU allocation to optimize concurrent program performance. Understand the difference between concurrency and parallelism, and learn to use GOMAXPROCS and NumCPU functions to adjust CPU utilization for efficient Go applications.
We'll cover the following...
Hopefully, you are fully aware by now that concurrency is not the same as parallelism. Now, Go provides us with building blocks of concurrency such as goroutines and channels which allow us to solve the problem concurrently. We can solve the problem through parallelism by running concurrent operations on additional CPUs. This is only possible if the problem to be solved is solvable by adding more CPUs. Thus, we can speed up solving problems by providing the necessary hardware. However, it is not necessary that our program will always speed up by adding CPUs. For example, by adding more CPUs, you are ...
