Overview of Intel® oneMKL LAPACK Routines for Data Parallel C++
The following pages describe the oneMKL LAPACK routines for Data Parallel C++ (DPC++) in detail, all of which are declared in the header file oneapi/mkl/lapack.hpp.
Several conventions are used throughout this document:
All oneMKL for DPC++ data types and non domain specific functions are inside the oneapi::mkl namespace.
All oneMKL LAPACK functions for DPC++ are inside the oneapi::mkl::lapack namespace.
For brevity, the sycl namespace is omitted from DPC++ object types, such as buffers and queues. For example a single-precision, 1D buffer A would be written buffer<float,1> &A instead of sycl::buffer<float,1> &A.
The routines are overloaded on precision. Each routine has a table detailing the supported precisions and devices.
Device Support
DPC++ supports the following types of devices:
CPU device: Performs computations on a CPU using OpenCL™.
GPU device: Performs computations on a GPU using OpenCL™ or Level Zero. Note that some or all of the computations may be performed on the CPU.
Each routine details the device types that are currently supported.
