============================== Release Notes: v0.1 ==============================

Initial release of the DiHydrogen Distributed Tensor Library.

DiHydrogen is the second version of the Hydrogen fork of the
well-known distributed linear algebra library, Elemental. DiHydrogen
aims to be a basic distributed multilinear algebra interface with a
particular emphasis on the needs of the distributed machine learning
effort, LBANN.

Internal features:

  • Support for the DistConv legacy library
  • Added multi-dimensional tensor class
  • Added support for older CUDA architectures v3.0+
  • Use CUB for memory management
  • Support for point-to-point (P2P) library
  • Support for NVSHMEM halo exchange

DistConv Legacy:

  • batchnorm
  • channel-wise softmax
  • concat
  • convolution
  • deconv
  • leaky-relu
  • pooling
  • relu
  • slice
  • softmax

Build system:

  • Require C++14
  • Added support for cuDNN v8

Bug fixes:

  • Fixed build issues with GCC8
