Efficient Offloading Decisions in Network-Aware Virtual Core Systems
Explore research issues on offloading decisions in OS, considering network status, loading, and virtual core for computation-intensive and I/O-intensive tasks. Analyze conditions for remote functions, automation, and storage integration. Discover strategies for returning results to local core and balancing local and remote storage in virtual environments.

Presentation Transcript
Research Issues • Offloading decision • Under what conditions should OS make offloading decisions. • Network status • Current loading • …etc. • Virtual core • computation-intensive -> I/O-intensive(wait for results)
Research Issues(Cont.) • Remote functions • Should be stateless and computation-intensive. • Modifications • By application developer. • Automation? • Not every function can be run on virtual core. • Foo(){ • intintermediateData = …; • Bar(intermediateData, …); • }
Research Issues(Cont.) • Return results to local core. • How to decide waiting for remote function or not. • Recovery.
Virtual Storage • Some applications need local files as input. • It is not practical for a remote function to read files from local storage. • Virtual storage • Combine local and remote storage. • We can upload and synchronize the files to remote storage in background. • The remote functions read the file directly from remote storage.
