2. Consider the following pseudocode. Including the initial parent process, how many processes, main threads, and worker threads are created? Answer in the blanks below. Briefly explain or draw a diagram to support your answer; otherwise, your score will be deducted. Note that the pthread_create(...) command, here, is to create a worker thread.

Please can you help me with the code that I have contributed, as I played a role in its development. Please ensure that only my code is utilized. This code should be written in C, and I have provided a portion of it below. Question that I need help with: You need to use the pthread for matrix multiplication. Each thread from the threadpool should be responsible for computing only a partof the multiplication (partial product as shown in the above picture –all Ti(S) are called a partical product). Your main thread should splitthe matrices accordingly and create the partial data arrays that areneeded to compute each Ti. You must create a unique task with thedata and submit it to the job queue. You can compute the partialproducts concurrently as long as you have threads available in thethreadpool. You have to remove the task the from queue and submitto a thread in the threadpool. You should define the number ofthreads to be 5 and keep it dynamic so that we can test the samecode with a…

About fork() return value: This slide said fork command return an integer. In my understanding, both parent and child processes are running concurrently after this code. So, why the slide said "running in newly created child process" when the return value =0? Does it mean that the child process is not running when the return value>0? It said "running in parent process" when the return value>0.
Does "many processes" imply the same thing as "many threads" or does it indicate something else entirely? Can you explain what you said?
