Cache oblivious stencil computations
We present a cache oblivious algorithm for stencil computations, which arise for example in finite-difference methods. Our algorithm applies to arbitrary stencils in n-dimension...

A Localized Tracing Scheme Applied to Garbage Collection
We present a method to visit all nodes in a forest of data structures while taking into account object placement. We call the technique a Localized Tracing Scheme as it improves lo...
