All Implemented Interfaces:

OpenCLObject

Direct Known Subclasses:

LwjglProgram

public abstract class Program
extends AbstractOpenCLObject

A wrapper for an OpenCL program. A program is created from kernel source code, manages the build process and creates the kernels.

Warning: Creating the same kernel more than one leads to undefined behaviour, this is especially important for createAllKernels()

Context.createProgramFromSourceCode(java.lang.String), createKernel(java.lang.String)

Method Detail

register

public Program register()

Description copied from interface: OpenCLObject

Registers this object for automatic releasing on garbage collection. By default, OpenCLObjects are not registered in the OpenCLObjectManager, you have to release it manually by calling OpenCLObject.release(). Without registering or releasing, a memory leak might occur.
Returns this to allow calls like Buffer buffer = clContext.createBuffer(1024).register();.

Specified by:

register in interface OpenCLObject

Overrides:

register in class AbstractOpenCLObject

Returns:

this

build

public abstract void build(java.lang.String args,
                           Device... devices)
                    throws KernelCompilationException

Builds this program with the specified argument string on the specified devices. Please see the official OpenCL specification for a definition of all supported arguments. The list of devices specify on which device the compiled program can then be executed. It must be a subset of Context.getDevices(). If null is passed, the program is built on all available devices.

Parameters:

args - the compilation arguments

devices - a list of devices on which the program is build.

Throws:

KernelCompilationException - if the compilation fails

See Also:

build()

build

public void build()
           throws KernelCompilationException

Builds this program without additional arguments

Throws:

KernelCompilationException - if the compilation fails

createKernel

public abstract Kernel createKernel(java.lang.String name)

Creates the kernel with the specified name.

Parameters:

name - the name of the kernel as defined in the source code

Returns:

the kernel object

Throws:

OpenCLException - if the kernel was not found or some other error occurred

createAllKernels

public abstract Kernel[] createAllKernels()

Creates all available kernels in this program. The names of the kernels can then by queried by Kernel.getName().

Returns:

an array of all kernels

getBinary

public abstract java.nio.ByteBuffer getBinary(Device device)

Queries a compiled binary representation of this program for a particular device. This binary can then be used e.g. in the next application launch to create the program from the binaries and not from the sources. This saves time.

Parameters:

device - the device from which the binaries are taken

Returns:

the binaries
