All Implemented Interfaces:

NSObject

public class MPSPredicate
extends NSObject

MPSPredicate [@dependency] This depends on Metal.framework

A MPSPredicate can be used to run MPS kernels subject to a predicate.

The MPSPredicate defines a way to refrain running a kernel on the GPU based on values computed on the GPU. That way one can build control flow operations that do the decisions on the GPU side mitigating the need to synchronize CPU and GPU execution. The predicate is used with the version of encode calls that take a object of type @ref MPSKernelEncodeOptions as a parameter (@see MPSCNNKernel for example). The code associated with the kernel's encode call is executed on the GPU if and only if the predicate is considered to be true. NOTE: It is advisable to release MPSPredicate objects promptly as they take a reference to a MTLBuffer object and therefore can keep the memory allocated for long periods of time.

init

public MPSPredicate init()

Overrides:

init in class NSObject

initWithBufferOffset

public MPSPredicate initWithBufferOffset(MTLBuffer buffer,
                                         long offset)

Initializes a MPSPredicate object with a buffer and given offset.

Parameters:

buffer - The buffer to use as a predicate.

offset - Byteoffset to the predicate buffer where the predicate is stored.

Returns:

A pointer to the newly initialized MPSPredicate object.

initWithDevice

public MPSPredicate initWithDevice(MTLDevice device)

Initializes a MPSPredicate object for a given device.

NOTE: The metal buffer used by the resulting MPSPredicate object may be shared among many MPSPredicate objects and therefore care must be used when writing to this buffer: writing to any other location in this buffer than the four bytes at the offset @ref predicateOffset results in undefined behavior.

Parameters:

device - The device the predicate is used with

Returns:

A pointer to the newly initialized MPSPredicate object.

new_objc

predicateBuffer

public MTLBuffer predicateBuffer()

[@property] predicateBuffer

The buffer that is used as the predicate

predicateOffset

public long predicateOffset()

[@property] predicateOffset

Location of the predicate in bytes, must be multiple of four.

If the uint32_t value stored at this location in @ref predicateBuffer is other than zero, then the predicate is considered to be true and the code is executed on the GPU. With this property a single MPSPredicate object can be used with multiple different predication operations. Default = 0;

predicateWithBufferOffset

public static MPSPredicate predicateWithBufferOffset(MTLBuffer buffer,
                                                     long offset)

Initializes a MPSPredicate object with a buffer and given offset.

Parameters:

buffer - The buffer to use as a predicate.

offset - Byteoffset to the predicate buffer where the predicate is stored.

Returns:

A pointer to the newly initialized MPSPredicate object.
