oneAPI V1.1 rev 1

Ray Tracing

Ray tracing capabilities have been added to the oneAPI specification providing software developers across the industry the ability to “write once” for high-fidelity ray-traced computations across multiple vendors’ systems and accelerators. Standardizing these interfaces provides well-designed, tried and true APIs and options for a broad set of compute and rendering infrastructure development.

The ray tracing functionality is subdivided into several domains within the oneAPI Specification:

• Geometric ray tracing computations
• Volumetric computation and rendering
• Image denoising
• Scalable rendering and visualization infrastructure

The set of Ray Tracing APIs include the following, which are in active use via the Intel® oneAPI Rendering Toolkit:

• Embree
• Open Volume Kernel Library
• Open Image Denoise
• OSPRay

oneMKL

Introduces additional batched APIs for dense linear algebra. Sparse matrix-dense matrix product has been extended to support both row and column major layout for the dense matrix. The input USM pointers in the vector math APIs are now const qualified. To align with changes in SYCL 2020, all oneMKL USM APIs were updated to take an (optional) std::vector of input events instead of sycl::vector_class. Other changes include minor clarifications and bug fixes.

DPC++

The new extensions listed as part of oneAPI 1.1 include simplified device selection through text-based filtering, a default context for each platform to simplify common coding patterns, interoperability with devices that use Level Zero as a backend, an easier to use kernel-scope local memory allocation mechanism, GPU-specific information queries, FPGA-specific performance tuning controls, and a sub-group mask feature.

DPC++ features that were incorporated into the SYCL 2020 spec were removed from this document.

oneVPL

New AV1 encode features. Enabled support for planar I422, I210, and BGR formats. Added surface pool interface for surface management.

Level Zero

Updates included significantly improved image processing functionality, better interoperability with other APIs and operating systems, new extensions for floating-point atomics and additional subgroup operations, and extensions to tune and optimize the way memory is allocated and kernels are scheduled on specific devices.
