This is the release note of v10.0.0a2. See here for the complete list of solved issues and merged PRs.

We are running a Gitter chat for general discussions and quick questions. Feel free to join the channel to talk with developers and users!

Highlights

• CuPy now supports CUDA 11.3 (cupy-cuda113) and AMD ROCm 4.2 (cupy-rocm-4-2) and binary wheels are now available on PyPI.
• The following Python syntax and new APIs can now be used in JIT target functions.
  • Calling len, min, max Python built-ins.
    • len(arr): Equivalent to arr.shape[0].
    • min(scalar1, scalar2, ...): Returns the minimum value of the inputs.
    • max(scalar1, scalar2, ...): Returns the maximum value of the inputs.
  • Accessing .ndim, .size attributes of ndarray.
  • Unpacking nested tuples.
    • (x, y), z = ...
  • jit.grid() API, similar to numba.cuda.grid.
    • x, y, z = cupyx.jit.grid(3) (x is equal to threadIdx.x + blockIdx.x * blockDim.x.)
  • Warp shuffle and sync functions.
    • cupyx.jit.shfl_down_sync(mask, var, val_id) (__shfl_down_sync(mask, var, val_id))
• cupyx.scipy.sparse.{coo,csr,csc}_matrix now provides the reshape method.

Changes without compatibility

Drop CUDA 9.2 & NCCL 2.4 Support (#5214)

CUDA 9.2 and NCCL 2.4 are no longer supported in CuPy v10.

Changes in Stream behavior (#5251)

The same cupy.cuda.Stream instance can now safely be shared between multiple threads. To achieve this, CuPy v10 will not destroy the stream (i.e., call cudaStreamDestroy) if the stream is the current stream of any thread.

Known Issues

• cupy-cuda111 wheels only support CUDA 11.1.1 and will not work with CUDA 11.1.0 (#5313).
• cupy-cuda110 and cupy-cuda111 wheels are not available yet in PyPI. In the meantime, they can be downloaded from the Assets section below. See #4971 for detailed instructions.

Changes

New Features

• Add reshape method for COO, CSR and CSC matrices (#5301)

• Support Numba-like jit.grid() syntax in CuPy JIT (#5334)
• Support warp shuffle and sync functions in CuPy JIT (#5335)

Enhancements

• Do not use handles unless requested in cupy.show_config() (#5073)
