What’s new in Version 1.0.0b2 (December, 2020)

Performance Enhancements

  • Improved performance of universal functions with multi-dimensional arrays.

  • Improved performance of broadcasting operations from a scalar value to an ndarray.

  • Improved performance of arccos() and arctanh().

  • Improved performance of random number generators by changing the number of threads to be execeted on VE.

Problem Fixes

  • Fixed a bug in sort() that might cause a freeze of Python interpreter at the end of the program.

  • Fixed a bug in matmul() that returned invalid results when input ndarrays (a and b) fulfill any of the following conditions:

    • a.flags.c_congituous is False and a.flags.f_contiguous is False

    • b.flags.c_congituous is False and b.flags.f_contiguous is False

  • Fixed a bug in prof.print_run_stats() that might showed negative elapsed time.
