This graph shows which files directly or indirectly include this file:

Macros
#define	CELER_DEVICE_PLATFORM   none
	API prefix token for the device offloading type.
#define	CELER_DEVICE_PLATFORM_UPPER_STR   ""
#define	CELER_DEVICE_API_SYMBOL(TOK)   void
	Add a prefix "hip" or "cuda" to a code token.
#define	CELER_EU_PER_CU   0
	Execution units per compute unit.
#define	CELER_DEVICE_RUNTIME_INCLUDED
	This macro informs downstream Celeritas code (namely, Stream) that it's safe to use types from the device APIs.

Variables
int const	CorecelDeviceRuntimeApiHh
	Declare a dummy variable for disabled CELER_DEVICE_API_CALL calls.

Detailed Description

Include CUDA or HIP runtime APIs for compiling with host/cc compiler.

Macro Definition Documentation

CELER_EU_PER_CU

#define CELER_EU_PER_CU   0

Execution units per compute unit.

AMD multiprocessors each have 4 SIMD units per compute unit, but there is no device attribute or compiler definition that provides this information. For CUDA, each streaming multiprocessor (MP) is a single "execution unit" and a "compute unit".

Variable Documentation

CorecelDeviceRuntimeApiHh

int const CorecelDeviceRuntimeApiHh

extern

Declare a dummy variable for disabled CELER_DEVICE_API_CALL calls.

With this declaration, the build will fail if this include is missing. (Unfortunately, since the use of this symbol is embedded in a macro, IWYU won't include this file automatically.)
