MPSState.h SYNOPSIS
#import <MPSCore/MPSCoreTypes.h> Classes class MPSStateResourceList struct MPSStateTextureInfo class MPSState Typedefs typedef struct MPSStateTextureInfo MPSStateTextureInfo typedef enum MPSStateResourceType MPSStateResourceType typedef NSArray< MPSState * > MPSStateBatch Enumerations enum MPSStateResourceType { MPSStateResourceTypeNone, MPSStateResourceTypeBuffer, MPSStateResourceTypeTexture } Functions NSUInteger MPSStateBatchIncrementReadCount (MPSStateBatch *__nullable batch, NSInteger amount) '' NSUInteger void MPSStateBatchSynchronize (MPSStateBatch *__nonnull batch, __nonnull id< MTLCommandBuffer > cmdBuf) '' Typedef Documentation typedef NSArray<MPSState*> MPSStateBatch typedef enum MPSStateResourceType MPSStateResourceType" typedef struct MPSStateTextureInfo MPSStateTextureInfo Enumeration Type Documentation enum MPSStateResourceType Enumerator MPSStateResourceTypeNone MPSStateResourceTypeBuffer MPSStateResourceTypeTexture Function Documentation NSUInteger MPSStateBatchIncrementReadCount (MPSStateBatch *__nullable batch, NSInteger amount) raise or lower the readcount of a batch by a set amount In some circumstances, a MPSState may appear in a MPSStateBatch multiple times. This is particularly common when the MPSState serves as an accumulator across the entire batch, such as when accumulating gradients for convolution weight update or batch statistics for batch normalization. A naive function would then end up incrementing the state multiple times, probably leading to an error. MPSStateBatchIncrementReadCount() will efficiently increment the readCounts of each object in the batch only once, avoiding this problem. Parameters: batch The MPSStateBatch to increment amount The value to add to the read count for each unique state in the batch Returns: The number of different objects in the batch NSUInteger void MPSStateBatchSynchronize (MPSStateBatch *__nonnull batch, __nonnull id< MTLCommandBuffer > cmdBuf) Call [MTLBlitEncoder synchronizeResource:] on unique resources Author Generated automatically by Doxygen for MetalPerformanceShaders.framework from the source code.
