How do I terminate multiprogram workloads?
• There are some very fundamental issues with whatever approach you choose. Here are your options: • Terminate as soon as any thread reaches a particular maximum number of instructions. This option is equivalent to max_insts_any_thread. The potential problem here is that because of the inherent non-determinism of multithreaded programs, there is no way to ensure that all experiments do the same work. You might also not get the same amount of work done. For example, if you have two threads, one of them must reach the maximum. The other could either execute no instructions, or could execute max-1 instructions. The benefit of this approach is that all threads are running fully until the simulation terminates (provided that none of the threads terminate early due to some other condition.) • Terminate once all threads have reached a maximum number of instructions. This option is equivalent to max_insts_all_threads. In this mode, we make sure all threads do at least a certain amount of work,
