1)Explore issues in design of petaComputer machine models which will support the controllable hierarchical memory systems in a range of important architectures
-
Research and development in areas of findings 3) and 4)
|
|
2)Explore techniques for control of memory hierarchy for petaComputer architectures
|
3)Explore issues in designing layered software architectures -- particularly efficient mapping and efficient interfaces to lower levels
-
Use context of petaflop applications and machines
-
e.g. HPF is a possible layer while HPF Extrinsics is an interface to a lower (MPI) layer
