Preferred Networks Releases CuPy v13

Over 140 signal processing functions added through support of Chan Zuckerberg Initiative


TOKYOJanuary 18, 2024 – Preferred Networks, Inc. (PFN) today released CuPy™ v13, the new major update to the open-source library for general-purpose matrix calculation.

CuPy v13 provides the following new features:

  • Multi-GPU Distributed Array (Preview)
    A sharded array that distributes processing across multiple GPUs to perform operations has been added. This feature was initially developed during the PFN Summer Internship Program 2023.
  • Support Import without an installed GPU Toolkit
    It is now possible to import CuPy in environments where NVIDIA CUDA is not installed. This makes it easier to write codes that support both NumPy and CuPy.

Please see the announcement in the CuPy blog for more details.


PFN will continue to swiftly incorporate the latest research outcomes into CuPy while collaborating with supporting companies and open source communities.
