Recommendations 1) to 3) Memory and Software Hierarchy

Recommendations 1) to 3) Memory and Software Hierarchy

• 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
  • Use testbeds
• 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
