Automatic Adaptation of Tunable Distributed Applications

摘要

Current-day applications are written to execute on a wide range of platforms ranging from fast desktop computers to mobile laptops all the way to hand-held PDAs and cellular phones, spanning several orders of magnitude in processing, storage, and communication capabilities. Applications running on these platforms may exhibit diverse and unpredictable performance because of platforms heterogeneity and varying resource availability, resulting from competition with other applications or from navigation of applications themselves to a different execution environment.
