DEVITO

  • I'm the lead developer of Devito, a software to automatically generate optimized iterative methods based on (but not limited to) stencil computation. Our primary focus is finite differences for seismic inversion. In a typical seismic inversion operator solving a PDE is just one of the many necessary steps -- so, over time, Devito has evolved and become able to generate fairly arbitrary, sophisticated loop nests, including typical stencil updates, advanced boundary conditions, interpolation, tensor contractions, etc.

OTHER SOFTWARE

This is a list of software I've contributed to in the past, mostly during my PhD. Some of these are still active projects.

  • I'm the author of COFFEE, a tool for optimising compute-intensive expressions embedded in (possibly non-perfect) loop nests. COFFEE is integrated with Firedrake -- an automated system for the solution of partial differential equations using the finite element method. COFFEE is/will be replaced by TSFC, although most of its optimizations and algorithms will remain the same -- just implemented at a higher level of abstraction.
  • I also have developed SLOPE, a run-time system for fusing and tiling loops with indirect memory accesses (e.g., A[B[i]]). The library ships a Python interface that can be used for integration with scientific codes based on Python and run-time code generation. I integrated SLOPE with Firedrake.
  • I'm one of the contributors of PyOP2, another key component of Firedrake. PyOP2 is responsible for applying numerical kernels over unstructured meshes.
