Research:

During the initial port of the IBM XL production compiler to the SPEs (the 8 SIMD-centric attached processors in the Cell Broadband Engine architecture), I have addressed SPE-specific scheduling and bundling issues, including compiler techniques to prevent instruction fetch starvation. I currently contribute to the automatic generation of SIMD code targeting the SIMD units found in the CELL (SPE/VMX), Power (VMX), and BlueGene/L (double-precision floating-point) architectures, focusing on data alignment related issues.

Prior research interests include instruction-level parallelism, predicated execution, profiling techniques, and software pipelining.
