Adaptive CPU Resource Management for Multicore Platforms

Vanessa Romero Segovia

Abstract

The topic of this thesis is adaptive CPU resource management for multicore platforms. The work was done as a part of the resource
manager component of the adaptive resource management framework
implemented in the European ACTORS project. The framework dynamically
allocates CPU resources for the applications. The key element of the
framework is the resource manager that combines feedforward and
feedback algorithms together with reservation techniques. The
reservation techniques are supported by a new Linux scheduler through
hard constant bandwidth server reservations. The resource requirements
of the applications are provided through service level tables. Dynamic
bandwidth allocation is performed by the resource manager which adapts
applications to changes in resource availability, and adapts the
resource allocation to changes in application requirements. The
dynamic bandwidth allocation allows to obtain real application models
through the tuning and update of the initial service level tables
