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 to be referenced in disabled CELER_BLAH 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.)
