Detailed Description

Calculation server name space.

Function Documentation

context_error_notify()

void CL_CALLBACK Aqua::CalcServer::context_error_notify	(	const char *	errinfo,
		const void *	private_info,
		size_t	cb,
		void *	user_data
	)

Runtime error reporting tool.

Errors reported in this way directly depends on the implementation.

Parameters

errinfo	is a pointer to an error string.
private_info	pointer to binary data that is returned by the OpenCL implementation that can be used to log additional information helpful in debugging the error.
cb	Size of the binary data, #private_info.
user_data	Current tool name.

create_command_queue()

cl_command_queue Aqua::CalcServer::create_command_queue	(	cl_context	context,
		cl_device_id	device,
		cl_int *	errcode_ret
	)

Create an OpenCL command queue.

This function is just a wrapper for backguard compatibility. More specifically, clCreateCommandQueue is deprecated since OpenCL 1.2

Parameters

context	OpenCL context
device	OpenCL device
errcode_ret	Returning error code

cursorVisitor()

CXChildVisitResult Aqua::CalcServer::cursorVisitor	(	CXCursor	cursor,
		CXCursor	parent,
		CXClientData	client_data
	)

Main traverse method, which will parse all tokens except functions declarations.

Parameters

cursor	the cursor whose child may be visited. All kinds of cursors can be visited, including invalid cursors (which, by definition, have no children).
parent	the visitor function that will be invoked for each child of parent.
client_data	pointer data supplied by the client, which will be passed to the visitor each time it is invoked.

Returns

CXChildVisit_Continue if a function declaration is found, CXChildVisit_Recurse otherwise.

Here is the call graph for this function:

functionDeclVisitor()

CXChildVisitResult Aqua::CalcServer::functionDeclVisitor	(	CXCursor	cursor,
		CXCursor	parent,
		CXClientData	client_data
	)

Method traverse method, which will parse the input arguments.

Parameters

cursor	the cursor whose child may be visited. All kinds of cursors can be visited, including invalid cursors (which, by definition, have no children).
parent	the visitor function that will be invoked for each child of parent.
client_data	pointer data supplied by the client, which will be passed to the visitor each time it is invoked.

Returns

CXChildVisit_Continue.

sigint_handler()

void Aqua::CalcServer::sigint_handler

(

int

s

)

Handle SIGINT signals.

The first time a SIGINT is received, Aqua::CalcServer::sigint_received is set to true, such that, at the end of the current time step the simulation will stop, the last output will be printed, and the resources will be correctly released.

If SIGINT is received twice, then this handler will enforce the inmediate program exit.

Parameters

s	Recevied signal, SIGINT
