Research:

My most recent work has been on retargeting the IBM XL compilers to the Cell Broadband Engine Architecture. In the initial stages I worked on modifying many of the major optimization phases of the backend to take account of the new SIMD ISA of the SPEs, and on instruction selection for the SPE. I also contributed to the early work on automatic simdization. Latterly, I have been involved in exploiting the parallelism of the chip by implementing OpenMP, and in work on automatic techniques for managing the movement of data from System Memory to the Local Stores. In particular, I designed and implemented a compiler-managed software cache.
