Porting to MIOpen

Porting to MIOpen#

The following is a summary of the key differences between MIOpen and cuDNN.

  • Calling miopenFindConvolution*Algorithm() is mandatory before calling any Convolution API

  • The typical calling sequence for MIOpen Convolution APIs is:

    • miopenConvolution*GetWorkSpaceSize() (returns the workspace size required by Find())

    • miopenFindConvolution*Algorithm() (returns performance information for various algorithms)

    • miopenConvolution*()

MIOpen supports:

  • 4D tensors in the NCHW and NHWC storage format; the cuDNN __“\*Nd\*”__ APIs don’t have a corresponding MIOpen API

  • __`float(fp32)`__ datatype

  • __2D Convolutions__ and __3D Convolutions__

  • __2D Pooling__

MIOpen doesn’t support:

  • __Preferences__ for convolutions

  • Softmax modes (MIOpen implements the __SOFTMAX_MODE_CHANNEL__ flavor)

  • __Transform-Tensor__, __Dropout__, __RNNs__, and __Divisive Normalization__

Useful MIOpen environment variables include:

  • MIOPEN_ENABLE_LOGGING=1: Logs all the MIOpen APIs called, including the parameters passed to those APIs

  • MIOPEN_DEBUG_GCN_ASM_KERNELS=0: Disables hand-tuned ASM kernels (the fallback is to use kernels written in a high-level language)

  • MIOPEN_DEBUG_CONV_FFT=0: Disables the FFT convolution algorithm

  • MIOPEN_DEBUG_CONV_DIRECT=0: Disables the direct convolution algorithm
