Class KHRInitializeMemory

java.lang.Object

org.lwjgl.opencl.KHRInitializeMemory

public final class KHRInitializeMemory
extends Object

Native bindings to the khr_initialize_memory extension.

This extension adds support for initializing local and private memory before a kernel begins execution.

Memory is allocated in various forms in OpenCL both explicitly (global memory) or implicitly (local, private memory). This allocation so far does not provide a straightforward mechanism to initialize the memory on allocation. In other words what is lacking is the equivalent of calloc for the currently supported malloc like capability. This functionality is useful for a variety of reasons including ease of debugging, application controlled limiting of visibility to previous contents of memory and in some cases, optimization.

Field Details

CL_CONTEXT_MEMORY_INITIALIZE_KHR

public static final int CL_CONTEXT_MEMORY_INITIALIZE_KHR

Accepted as a property name in the properties parameter of CreateContext.

Describes which memory types for the context must be initialized. This is a bit-field, where the following values are currently supported:

• CL_CONTEXT_MEMORY_INITIALIZE_LOCAL_KHR – Initialize local memory to zeros.
• CL_CONTEXT_MEMORY_INITIALIZE_PRIVATE_KHR – Initialize private memory to zeros.
