Objectives | |
| I have over 30 years experience as a software developer and manager in technology. In this time, I have worked for major hardware manufacturers, major video game studios, a major animated motion picture, and with Internet broadcasting of independent films. I have worked for startups and large public corporations. I have built code, systems, platforms and teams. I am currently looking at the problems associated with GPUs programming from the point of view of the compiler — programming models, heterogeneous compute, and their implications on hardware architectures. |

Senior Engineering Manager, Developer TechnologiesI have built and managed and org with several teams supporting Apple Silicon on all Apple devices: Apple Watch, AppleTV, iPhone, iPad, Macs and Apple Vision Pro. We build LLVM-based compiler backends and engage with the architecture, modelling, micro architecture, silicon enginering, driver, Xcode and Swift teams; we support the program from pre-silicon to production and consistently ship multiple products every year to billions of devices.Engineering Manager, Developer TechnologiesI manage a team of 10-12 engineers supporting multiple GPU backends covering all current iOS devices. The team's expertise spans a broad domain of knowledge including: LLVM, compiler optimizations, code transformation, code generation, computer graphics, shading languages, hardware architecture. We strive to compile quickly and generate small code that runs fast, while minimizing power and enabling the hardware team to minimize area. We cover both the pre-silicon and production aspects of the development cycle.Compiler Backend Engineer, LLVM TeamCompiler backend engineer on GPU code generation team. I am focused on enabling future graphics and compute technologies by maximizing performance and minimizing power consumption of the generated code, while keeping compile times minimal. | |

Hardware and Software Architect, Visual and Parallel Computing Group (VPG), Intel Architecture Group (IAG)Ported the open-source Intel SPMD Program Compiler (ISPC) to Knight's Corner (KNC)—Intel's first Xeon Phi processor out of the Many Integrated Core (MIC) architecture. ISPC is an LLVM-based compiler, the KNC backend emits C++ and intrinsics.Helped customers port kernels from various HPC workloads from Xeon to Xeon Phi, and then extract performance out of the machine. These workloads represent an assortment of C/C++/Fortran mini-applications representing larger applications in use at the U.S. Department of Energy (DOE) National Labs. Worked on various interoperability issues between ISPC, Fortran, OpenMP and MPI. Performed studies on various hardware features and their impact on software for the Knight's family of processors. This included evaluating impact of ISA changes on key workload performance, as well as the impact of various micro-architectural features—including page size, TLBs, caches. Used and modified the Intel architecture simulator, as well as custom-built SystemC-based infrastructure. Some of this work has resulted in patent applications. | |
Established the Intel Victoria siteIdentified and selected office space for Intel in Victoria. Coordinated across several divisions for budgeting, planning and realization of the required upgrades to the space, in accordance with Intel standards. Worked with the contractors' superintendent during the construction project which lasted two months. Managed setup of network infrastructure, IT systems, phone and security systems. Planned the move into the new space. I remain the site manager responsible for IT, security and day-to-day operations; on top of my responsibilities as an architect. | |
Graphics and Software Architect, Visual and Parallel Computing Group (VPG), Intel Architecture Group (IAG)Part of the team that wrote the high-performance DX driver for Larrabee. Work included adding support for DX9 and DX10 features to the driver, shader compiler, state management system and DX conformance testing (WHQL). | |
Graphics Architect, Advanced Rendering Technologies (ART), Software Solutions Group (SSG)Designed and developed the software infrastructure for the demand-paged texturing system for Larrabee. Architected and coordinated work between multiple groups at Intel: hardware architecture, functional simulation, operating system development, shader compiler development, image and compression routines development, DirectX driver development, native system API development, native rendering API development and game developer support. Some of this work has resulted in patent applications.Industry-Academy liaison between Intel and the University of Victoria. Worked with the department of Computer Science at UVic, coordinated grant applications from UVic faculty with Intel, tracked students participating in sponsored research, tracked NDA coverage. Obtained grant renewals. Worked with Canadian funding agencies (NSERC and MITACS). | |
