Calculating makespan among several machines
$begingroup$
I have a question about makespan calculation. I know that makespan formula is like this:
Makespan = Time of completion of last job - Starting time of the first
job
but I can't figure out how we should use it for several machines. I have a load balancing algorithm that helps in processing of several independent jobs on 3 homogeneous machines. A central coordinator gathers the load on each machine (load = number of tasks on each machine) and if there is an overloaded device, the coordinator will move some of its tasks to a less-loaded machine. By the way jobs are not consisted of small tasks and all the job should be done on a single machine. I want to calculate makespan for this algorithm.
Now in order to calculate makespan, should I calculate makespan for each machine separately
or
I should do this among all machines? I mean should I find the time of earliest job arrived to these machines and also find the time of last job among 3 machines and apply the above formula to them?
