Delegate TakeKernel

Assembly

NumSharp.dll

IL-emitted gather kernel for np.take. The source is treated as a 3-D layout (outerSize, maxItem, innerSize-bytes). For each (outer, j) pair the kernel reads indices[j], applies mode, and copies innerSize bytes from the source slab to the destination position.

public delegate long TakeKernel(byte* src, long* indices, long indicesCount, long outerSize, long maxItem, long innerSize, int mode, byte* dst)

Parameters

src byte*

IL-emitted gather kernel for np.take. The source is treated as a 3-D layout (outerSize, maxItem, innerSize-bytes). For each (outer, j) pair the kernel reads indices[j], applies mode, and copies innerSize bytes from the source slab to the destination position.

indices long*

IL-emitted gather kernel for np.take. The source is treated as a 3-D layout (outerSize, maxItem, innerSize-bytes). For each (outer, j) pair the kernel reads indices[j], applies mode, and copies innerSize bytes from the source slab to the destination position.

indicesCount long

IL-emitted gather kernel for np.take. The source is treated as a 3-D layout (outerSize, maxItem, innerSize-bytes). For each (outer, j) pair the kernel reads indices[j], applies mode, and copies innerSize bytes from the source slab to the destination position.

outerSize long

IL-emitted gather kernel for np.take. The source is treated as a 3-D layout (outerSize, maxItem, innerSize-bytes). For each (outer, j) pair the kernel reads indices[j], applies mode, and copies innerSize bytes from the source slab to the destination position.

maxItem long

IL-emitted gather kernel for np.take. The source is treated as a 3-D layout (outerSize, maxItem, innerSize-bytes). For each (outer, j) pair the kernel reads indices[j], applies mode, and copies innerSize bytes from the source slab to the destination position.

innerSize long

IL-emitted gather kernel for np.take. The source is treated as a 3-D layout (outerSize, maxItem, innerSize-bytes). For each (outer, j) pair the kernel reads indices[j], applies mode, and copies innerSize bytes from the source slab to the destination position.

mode int

IL-emitted gather kernel for np.take. The source is treated as a 3-D layout (outerSize, maxItem, innerSize-bytes). For each (outer, j) pair the kernel reads indices[j], applies mode, and copies innerSize bytes from the source slab to the destination position.

dst byte*

IL-emitted gather kernel for np.take. The source is treated as a 3-D layout (outerSize, maxItem, innerSize-bytes). For each (outer, j) pair the kernel reads indices[j], applies mode, and copies innerSize bytes from the source slab to the destination position.

Returns

long

outerSize * indicesCount on success. On RAISE OOB the returned value is the row-major index of the first failing (outer, j) pair.
