Method Detail

decompressAsync

public static void decompressAsync(long chunkSize,
                                   BaseDeviceMemoryBuffer[] origInputs,
                                   BaseDeviceMemoryBuffer[] outputs,
                                   Cuda.Stream stream)

Asynchronously decompress a batch of buffers

Parameters:

chunkSize - maximum uncompressed block size, must match value used during compression

origInputs - buffers to decompress, will be closed by this operation

outputs - output buffers that will contain the compressed results, each must be sized to the exact decompressed size of the corresponding input

stream - CUDA stream to use
