Specialized component containing compute resources that can quickly execute a subset of operations. Examples include CPU, FPGA, GPU.
See also: Device
Communicates the desired location (host, device) and mode (read, write) of access.
Code that executes on the host.
Memory object that communicates the type and number of items of that type to be communicated to the device for computation.
Command Group Scope
Code that acts as the interface between the host and device.
Issues command groups concurrently.
A grouping of processing elements into a ‘core’ that contains shared elements for use between the processing elements and with faster access than memory residing on other compute units on the device.
An accelerator or specialized component containing compute resources that can quickly execute a subset of operations. A CPU can be employed as a device, but when it is, it is being employed as an accelerator. Examples include CPU, FPGA, GPU.

Code that executes on the device rather than the host. Device code is specified via lambda expression, functor, or kernel class.
An open source project is adding SYCL* support to the LLVM C++ compiler.
Application binary that contains device code for multiple devices. The binary includes both the generic code (SPIR-V representation) and target specific executable code.
Archive or library of object code that contains object code for multiple devices. The fat library includes both the generic object (SPIR-V representation) and target specific object code.
File that contains object code for multiple devices. The fat object includes both the generic object (SPIR-V representation) and target specific object code.
A CPU-based system (computer) that executes the primary portion of a program, specifically the application scope and command group scope.
Code that is compiled by the host compiler and executes on the host rather than the device.
Formatted opaque memory object that is accessed via built-in function. Typically pertains to pictures comprised of pixels stored in format like RGB.
Code that executes on the device.
Short for N-Dimensional Range, a group of kernel instances, or work item, across one, two, or three dimensions.
Individual engine for computation that makes up a compute unit.
Code in the same file that can execute on a host and accelerator(s).
Binary intermediate language for representing graphical-shader stages and compute kernels.
A standard for a cross-platform abstraction layer that enables code for heterogeneous processors to be written using standard ISO C++ with the host and kernel code for an application contained in the same source file.
Collection of work-items that execute on a compute unit.
Basic unit of computation in the oneAPI programming model. It is associated with a kernel which executes on the processing element.
