Worked on the intel/torch-xpu-ops repository to enhance SYCL backend compatibility and numerical consistency across XPU devices. Over three months, migrated core floating-point and mathematical operations from standard C++ libraries to SYCL-native APIs, addressing device-specific discrepancies and improving portability. Refactored kernels and helper headers to standardize math interfaces, introduced explicit type handling for low-precision operands, and expanded device-side math wrappers for functions like exp, sqrt, and trigonometric operations. Improved build reliability by updating CMake configurations and warning handling. Leveraged C++, SYCL, and CMake to deliver backend-agnostic, high-performance computing solutions supporting cross-platform numerical correctness and future XPU optimizations.

Jul 1, 2026July 2026 monthly summary for intel/torch-xpu-ops focused on SYCL-native Math Compatibility Migration for XPU. Delivered end-to-end migration of device-side math operations to SYCL-native implementations across the XPU backend, with updates to build flags, wrappers in XPUMathCompat.h, and migration across multiple kernel files to support sqrt, trig, exp, abs, and normcdf. Completed comprehensive refactor and coverage across critical paths, reducing device-host math divergence and enabling portable, SYCL-compliant execution on XPU targets.

May 1, 2026In May 2026, the torch-xpu-ops work centered on strengthening the SYCL backend to improve numerical accuracy, device compatibility, and portability. Key work migrated critical floating-point operations to SYCL-specific APIs to avoid std lib discrepancies and to leverage SYCL math primitives across kernels. The changes reduce device-specific numerical variability and pave the way for consistent performance on SYCL-enabled accelerators. Key deliverables during the month focused on two major areas: 1) Fmod/DivFloor precision improvements via SYCL math migration (f1a241ac5921a1fa56fb4202d1c09b78c4ed5d35): Replaced std::fmod with sycl::fmod and added explicit type handling in BinaryDivFloorKernel.cpp, as well as updated RemainderFloatingFunctor and FmodFloatingFunctor to use sycl::fmod with correct casting to opmath_t and back to scalar_t. 2) SYCL math API alignment across device kernels (3d1cff2241a70abc68adac364b8650458395d578): Migrated std::ceil and ceilf to sycl::ceil in several kernels (PsRoiAlignForward/Backward, PsRoiPoolForward/Backward, RoiAlign/Pool, GeometricFunctor, CeilFunctor, Upsample kernels), ensuring compatibility and avoiding standard library ceilings without changing business logic. Impact: Improved numerical precision and consistency across SYCL devices, enabling broader hardware support, reducing numerical edge-case bugs, and delivering more predictable performance for workload pipelines that rely on ROI operations, upsampling, and geometric distributions. Technologies/skills demonstrated: SYCL programming, kernel refactoring for backend-agnostic math APIs, explicit type handling and casting, cross-repo collaboration, and attention to numerical correctness in performance-sensitive paths.
