Detailed Description

OpenCL kernels compilation definitions.

In order to make AQUAgpusph more extensible, preprocessor definitions can be set, such that they will be defined for all the compiled kernels.

3 types of definitions can be practised:

• Named definitions, like -DHAVE_3D
• Value definitions, like -DNEIGH_CELLS=9
• Float evaluated definitions, like -DH=h, where h will be replaced by the variable value

The definitions are set between the following XML tags:

<Definitions>
</Definitions>

Warning

The definitions are made right after the variables setup, and they are set just one time, so you cannot use them to pass changing variables to the OpenCL kernels.

Member Function Documentation

define()

void Aqua::InputOutput::ProblemSetup::sphDefinitions::define	(	const std::string	name,
		const std::string	value,
		const bool	evaluate )

Add a new definition.

It can be repeated, such that the definition will be overwritten later by the last instance found.

Parameters

name	Name of the definition.
value	Value of the definition, empty for named definitions.
evaluate	True if the value should be evaluated as a math expression, false otherwise.

Here is the call graph for this function:

isDefined()

bool Aqua::InputOutput::ProblemSetup::sphDefinitions::isDefined

(

std::string

name

)

Reports if a the required name has been already defined.

Parameters

name	Name of the definition.

Returns

true if it is already defined, false otherwise.

undefine()

void Aqua::InputOutput::ProblemSetup::sphDefinitions::undefine

(

std::string

name

)

Undefine a registered definition.

Parameters

name	Name of the definition.

Field Documentation

evaluations

std::vector<bool> Aqua::InputOutput::ProblemSetup::sphDefinitions::evaluations

names

std::vector<std::string> Aqua::InputOutput::ProblemSetup::sphDefinitions::names

Name of the definition.

values

std::vector<std::string> Aqua::InputOutput::ProblemSetup::sphDefinitions::values
