GCFS: a GridComputing Framework Basedon Spaces

In ordertodevelop agridcomputing system ina simpler way,a gridcomputing frameworkwithspaces (GCFS)isproposed. Theframework consists ofthree layers thatinteract witheachother. Thegridapplication layer provides interfaces forcomputers tojointhegrid. Atthe spacemanagerlayer, a spaceservice canbedynamically created ordestroyed bytheevaluation algorithm. Thespace service layer coordinates gridnodesinasynchronous mode. Spaceservices andgridnodesallareregarded ascomputing resources. Task assignment is implemented by two procedures withQoS-based scheduling algorithms. The aboveideas havebeenapplied inagroupcompanyforthe simulation ofthird generation (3G)wireless systems, anditis foundthata lightweight gridcomputing platform canbe realized viaGCFS.Finally, thefuture improvement ofGCFS isdiscussed.
