22. Demo: cpu_burn.c #include int main() { int iMAX = 60000; int i,j; float fNORM, fMAX; float x,y; fMAX = iMAX; // convert to float fNORM = fMAX * fMAX; for (j=0;j<iMAX;j++) for (i=0;i<iMAX;i++) { y = i; // convert to float x = y*y/fNORM; } return 0; }

23. Submit file: universe = vanilla executable = cpu_burn.exe Error = err.$(Cluster).$(Process) Output = out.$(Cluster).$(Process) Log = log.$(Cluster).$(Process) Queue 5

24. Watch the Task Manager
