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 bufferA
would be writtenbuffer<float,1> &A
instead ofsycl::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.
