iere are n work processes, numbered from AiSo assume tha machine has an atomic increment instruction. Consider the following cod n n-process barrier that is supposed to be reusable: 0; go code executed by worker [1] : (await (count == count = 0; int count 0; # shared variables п-1);) go = 1; code executed by Worker [2:n] : (count++;) (await (go == %3D 1) ;) Explain what is wrong with the above code? x the code so that it works. Do not use any more shared variables, but yo troduce local variables

Question
Assume there are n worker processes, numbered from 1 to n. Also assume that your machine has an atomic increment instruction. Consider the following code for an n-process barrier that is supposed to be reusable: int count = 0; go = 0; # shared variables code executed by Worker [1] : ( await (count п-1) ;) == count = 0; go = 1; code executed by worker [2:n] : (count++;) (await (go == 1);) (a) Explain what is wrong with the above code? (b) Fix the code so that it works. Do not use any more shared variables, but may introduce local variables. you
