Interdevcopy: inter-device data copy library
Interdevcopy is a library for data transfer between devices including host and various accelerators.

The following environment is required to use Inter-Device Copy.

• Hardware: x86 server with vector engine
  • Vector Engine: VE10, VE10E and VE20
  • GPU: NVIDIA
• Operating System: RedHat Enterprise Linux / CentOS / Rocky Linux 8.4 or above
• VE driver, VEOS and AVEO with VE-GPU direct transfer support (preview release version) released on GitHub
  • https://github.com/veos-sxarr-NEC/veos/releases
• CUDA 11.7.0 or higher

You can install Inter-Device Copy by running the following commands.

• Install from your local computer
  1. Download the rpm packages from GitHub.
     At this time, download two of interdevcopy, interdevcopy-devel.
  2. Put the rpm packages to your any directory.
  3. Install the local rpm packages via yum command.

$ sudo yum install <path_to_interdevcopy_rpm> <path_to_interdevcopy-devel_rpm>

Packages required for building

• To build interdevcopy, AVEO with VE-GPU direct transfer support (veoffload-aveo, veoffload-aveo-devel and veoffload-aveorun-ve1) and CUDA 11 are required.
• It's using GNU make for library interdevcopy build and GNU Autoconf/Automake/Libtool for generating Makefile etc.
• It has been confirmed that the build can be done in the following conditions.
  • Compiler GCC: gcc-c++-8.5.0
  • GNU make: make-4.2.1
  • GNU Autoconf: autoconf-2.69
  • GNU Automake: automake-1.16.1
  • Libtool: libtool-2.4.6

Specify the configure option as follows and execute make install.

$ git clone https://github.com/SX-Aurora/interdevcopy.git
$ cd interdevcopy
$ ./bootstrap
$ ./configure --prefix=/opt/nec/interdevcopy --libdir=/opt/nec/interdevcopy/lib64 \
    --with-veo=/opt/nec/ve/veos --with-cuda=/usr/local/cuda
$ make
$ sudo make install
