Abstract
Consider the problem of scheduling a set of implicit-deadline sporadic tasks to meet all deadlines on a two-type heterogeneous multiprocessor platform where a task may request at most one of \(\left|R\right|\) shared resources. There are m 1 processors of type-1 and m 2 processors of type-2. Tasks may migrate only when requesting or releasing resources. We present a new algorithm, FF-3C-vpr, which offers a guarantee that if a task set is schedulable to meet deadlines by an optimal task assignment scheme that only allows tasks to migrate when requesting or releasing a resource, then FF-3C-vpr also meets deadlines if given processors \(2+ 3 \cdot \left\lceil \frac{|R|}{\min(m_1,m_2)}\right\rceil\) times as fast. As far as we know, it is the first result for resource sharing on heterogeneous platforms with provable performance.
