SDN is known as a decoupled architecture separatingthe control and data planes. The controller is in charge ofnetwork nodes through a southbound interface. However, it iscostly to impose all controllers to control each node separately. Meanwhile, the layout of controllers affects the network's abilityto respond to network events. Therefore, the controller placementis an important problem in SDN community...
The prevalence of control flow, recursive data structures, and general pointer accesses in ordinary programs renders the traditional automatic parallelization techniques unsuitable. OpenMP Decoupled Software Pipelining (DSWP) is proposed to exploit pipeline parallelism lurking in ordinary programs, which cannot be dealt with by traditional techniques. While cost model is important in helping evaluate...
Automatic decomposition is a compile technique that maps computation and data onto different processors, and array is one of the main targets processed. Certain arrays, whose migration is the most expensive, are termed as dominant arrays. Since every computing node has its own memory on distributed memory parallel computers (DMPCs), decompositions of dominant arrays have directly impact on the performance...
