CPU priority algorithm...

Mon Oct 24, 2011 3:24 pm

It's the CPU scheduling priority algorithm function.
But, Average turnaround time and Average waiting time are wrong.
Why is that?
Plz...Help me.

Code:: void func_prior(struct process *queue){ int* gantt=(int*)malloc(sizeof(int)*total); int next=0; int a, b=0, priority, i; // while (i < total){ for(i=0; i<total; ){ for (a=0; a<job; a++){ priority = 10; while(b < job){ // for (b=0, priority=11; b<job; b++){ if ( queue[b].arrive <= i && queue[b].priority < priority ) { priority=queue[b].priority; queue[b].priority = queue[a].priority; // queue[a].priority = priority; // }b++; } if ( queue[a].priority <= priority && queue[a].arrive <= i ){ for (b=0; queue[a].running>0; b++){ queue[a].running--; i++; queue[a].turnaround = i-queue[a].arrive; queue[a].waiting = queue[a].turnaround - queue[a].run; } if (queue[a].priority < job+1) queue[a].priority++; } } } func_print(queue); }
