5. Co-Allocation & Advance Reservation
Co-allocation is necessary because applications need simultaneously resources of different types: CPU and DATA and NETWORK
Advance Reservation of heterogeneous resources is necessary to guarantee end-to-end performance
Analysis of possible strategies and paradigms for rescheduling in case of resource fault or change in allocation
The different architectural approaches have to be investigated:
Reserv/co-alloc done by application
Reserv/co-alloc agents between appl and res.
Reserv/co-alloc global broker
