Your question is not clear. (1) What do your 3-digit labels after "e.g." represent? (I would have expected 4 digits, one for each of the 4 processors; but perhaps you were using a simpler system of 3 processors for illustration?) (2) For "3 possible workloads, running on 4 processors" how do you arrive at "5^4" (five to the fourth power, or 625?) as the number of permutations? (3) Your list of "e.g." labels includes "111" twice. Is the repetition an error? (If it isn't, I REALLY don't understand what you're trying to ask!) (4) Suppose that by "1111" one meant "workload #1, running on all 4 processors, and by "1112" one meant "workload #1 running on 3 processors and workload #2 running on the fourth". Do you wish to distinguish between "1112", "1121", "1211", and "2111"; or does "1112" suffice for all four possibilities? If the former, why do you not show examples like "213" and "132" (etc.) along with "123"? If the latter, why do you not have labels that are all monotonically increasing, like "113", instead of "331" and "332"?
If none of these questions are relevant, then ask your question again, more clearly this time, and probably describing more details about your project.
