Hi Pradeep, First of all I think the notion of optimal is not just a single dimension of being task duration, but also considering lots of other dimensions such as throughput, fairness, latency, SLA and more.
Mesos is a two level scheduler, which means it's not doing all the scheduling at a single point (master), but instead cooperate with frameworks to have a good scheduling decision. So Mesos can achieve it with multiple attributes or resources as you mentioned with the help of frameworks.
