fopenmp-targets, Qopenmp-targets

Enables offloading to a specified GPU target if OpenMP* features have been enabled.

Syntax

Linux:

-fopenmp-targets=keyword

Windows:

/Qopenmp-targets:keyword

Arguments

keyword

The only supported value for this argument is spir64.

When you specify spir64, the compiler generates an x86 + SPIR64 (64-bit Standard Portable Intermediate Representation) fat binary for Intel® GPU devices.

Default

OFF	If this option is not specified, no x86 + SPIR64 fat binary is created.

Description

This option enables offloading to a specified GPU target if OpenMP* features have been enabled.

To use this option, you must enable recognition of OpenMP* features by specifying one of the following options:

[q or Q]openmp
-fiopenmp (Linux*) or /Qiopenmp (Windows*)
-fopenmp (deprecated; it is equivalent to -qopenmp on Linux*)

The following shows an example:

  icx (or icpx) -fiopenmp -fopenmp-targets=spir64 matmul_offload.cpp -o matmul

When you specify -fopenmp-targets (Linux*) or /Qopenmp-targets (Windows*), C++ exception handling is disabled for target compilations.

For host compilations on Linux* systems, if you want to disable C++ exception handling, you must specify option -fno-exceptions.
