If there is no information how the task runtimes are dealt with in simulation. Without this crucial information of runtime scheduling of tasks, Is it possible to evaluate the any new approach?
If any proposed algorithm use no information about task runtimes. It is common that the runtime estimation are not known in advance, but they become known at runtime. So how the algorithm behaves at runtime, e.g. when one tasks finishes e.g. earlier than the other, when are VMs started and terminated. This is a crucial aspect of cloud resource provisioning, since clouds offer on-demand provisioning.
