Abstract
An
important emerging requirement for computing systems is the ability to adapt
at run time, taking advantage of local computing devices, and coping with
dynamically changing resources. Three
specific technical challenges in satisfying this requirement are to (1)
select an appropriate set of applications or services to carry out a
user’s task, (2) allocate (possibly scarce) resources among those applications,
and (3) reconfigure the applications or resource assignments if the situation
changes. In this paper we show how to provide a shared infrastructure that
automates configuration decisions given a specification of the user’s
task. The heart of the approach is an
analytical model and an efficient algorithm that can be used at run time to
make near-optimal (re)configuration decisions. We validate this approach both analytically
and by applying it to a representative scenario.
