Cache Programming for Scientific Loops Using Leases

Cache management is important in exploiting locality and reducing data movement. This paper studies a new type of programmable cache called the lease cache. By assigning leases, software exerts primary control on when how long stays Previous work has shown an optimal solution for ideal develops evaluates set practical solutions physical emulated FPGA with full suite PolyBench benchmarks. Compared to automatic caching, programming can further reduce movement by 10% over 60% size 16 times 3,000 size, techniques this realize 80% potential. Moreover, another 0.8% 20% after polyhedral optimization.
