Overview of Intel® oneAPI Math Kernel Library (oneMKL) LAPACK for DPC++
The following pages describe the oneMKL LAPACK routines for 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++ functions and data types are inside the mkl namespace.
For brevity, the cl::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.
A question mark (?) in a routine name stands for one or more characters (typically one of s, d, c, z) specifying the precision of the operation. Each routine has a table detailing the supported precisions and associated routine names.
Device Support
DPC++ supports several types of devices:
CPU device: Performs computations on a CPU using OpenCL™.
GPU device: Performs computations on a GPU.
Each routine details the device types are currently supported.
In the current release of oneMKL LAPACK for DPC++, all routines support at least CPU devices. GPU devices are supported in the current release only for the following routines:
