NLCPy is a library for accelerating performance of Python scripts using NumPy on SX-Aurora TSUBASA. Python programmers can use this library on Linux/x86 of SX-Aurora TSUBASA. NLCPy's API is designed based on NumPy's one. The current version provides a subset of NumPy's API.

Before the installation, the following components are required to be installed on your x86 Node of SX-Aurora TSUBASA.

• NEC SDK

  • required NEC C/C++ compiler version: >= 5.0.0
  • required NLC version: >= 3.0.0

• Alternative VE Offloading (AVEO)

  • required version: >= 3.0.2

  • If you install NLCPy from wheel, the runtime packages of Alternative VE Offloading(AVEO) are required.

    # yum install veoffload-aveo veoffload-aveorun-ve1 veoffload-aveorun-ve3
    

  • If you install NLCPy from source, the development packages of Alternative VE Offloading(AVEO) are required.

    # yum install veoffload-aveo-devel veoffload-aveorun-ve1-devel veoffload-aveorun-ve3-devel
    

• veosinfo3

  # yum install veosinfo3
  

• Python - required version: 3.6, 3.7, or 3.8

• NumPy - required version: >= v1.17

You can install NLCPy by executing either of following commands.

• Install from PyPI

  $ pip install nlcpy
  

• Install from your local computer

  1. Download the wheel package from GitHub.

  2. Put the wheel package to your any directory.

  3. Install the local wheel package via pip command.

     $ pip install <path_to_wheel>
     

The shared objects for Vector Engine, which are included in the wheel package, are tested by using NEC C/C++ Compiler Version 5.0.0 and NumPy v1.19.5.

Before building source files, please install following packages.

$ pip install numpy cython wheel
$ sudo yum install veosinfo3-devel
$ sudo yum install veoffload-aveo-devel veoffload-aveorun-ve1-devel veoffload-aveorun-ve3-devel

And, entering these commands in the environment where gcc and ncc commands are available.

$ git clone https://github.com/SX-Aurora/nlcpy.git
$ cd nlcpy
$ python3 setup.py build_ext --targ ve1,ve3,vh
$ python3 setup.py intall --targ ve1,ve3,vh
