Installing and Uninstalling the Data Compression SDK

Build an algorithm project using Huawei-developed lossless compression algorithms. The project identifies features of raw data and dynamically matches the optimal compression algorithm model to improve the data reduction rate. In addition, instruction-level optimization is performed for Kunpeng processors to accelerate compression.

The Data Compression SDK contains kunpeng-dc and kunpeng-dc-devel. kunpeng-dc is used to run Kunpeng data compression applications, and kunpeng-dc-devel is used to develop Kunpeng data compression applications. Therefore, to run a Kunpeng data compression application, you only need to install kunpeng-dc. To develop a Kunpeng data compression application, you need to install both kunpeng-dc and kunpeng-dc-devel.

Prerequisites

Processor architecture: Kunpeng 920
Server: Kunpeng server
OS: openEuler 20.03 LTS SP1, openEuler 22.03 LTS SP1, or Kylin V10 SP1

Installing and Uninstalling the Data Compression SDK

SDK installation and uninstallation (openEuler 20.03 LTS SP1)
1. Obtain the Data Compression SDK installation package from the Kunpeng mirror site.
2. Decompress the installation packages.
  1 2
  tar -zxvf kunpeng-dc-xxx.aarch64.tar.gz tar -zxvf kunpeng-dc-devel-xxx.aarch64.tar.gz
3. Go to the decompressed directories and install the RPM packages.
  kunpeng-dc:
  1
  rpm -ivh kunpeng-dc-xxx.aarch64.rpm
  kunpeng-dc-devel:
  1
  rpm -ivh kunpeng-dc-devel-xxx.aarch64.rpm
4. Uninstall the RPM packages.
  kunpeng-dc-devel:
  1
  rpm -e kunpeng-dc-devel
  kunpeng-dc:
  1
  rpm -e kunpeng-dc
SDK installation and uninstallation (openEuler 22.03 LTS SP1)
1. Obtain the Data Compression SDK installation package from the Kunpeng mirror site.
2. Decompress the installation packages.
  1 2
  tar -zxvf kunpeng-dc-xxx.aarch64.tar.gz tar -zxvf kunpeng-dc-devel-xxx.aarch64.tar.gz
3. Go to the decompressed directories and install the RPM packages.
  kunpeng-dc:
  1
  rpm -ivh kunpeng-dc-xxx.aarch64.rpm
  kunpeng-dc-devel:
  1
  rpm -ivh kunpeng-dc-devel-xxx.aarch64.rpm
4. Uninstall the RPM packages.
  kunpeng-dc-devel:
  1
  rpm -e kunpeng-dc-devel
  kunpeng-dc:
  1
  rpm -e kunpeng-dc
SDK installation and uninstallation (Kylin V10 SP1)
1. Obtain the Data Compression SDK installation package from the Kunpeng mirror site.
2. Decompress the installation packages.
  1 2
  tar -zxvf kunpeng-dc-xxx.aarch64.tar.gz tar -zxvf kunpeng-dc-devel-xxx.aarch64.tar.gz
3. Install the RPM packages.
  kunpeng-dc:
  1
  rpm -ivh kunpeng-dc-xxx.aarch64.rpm
  kunpeng-dc-devel:
  1
  rpm -ivh kunpeng-dc-devel-xxx.aarch64.rpm
4. Uninstall the RPM packages.
  kunpeng-dc-devel:

xxx indicates the version number.
Obtain the latest TAR.GZ installation packages from the URLs given above, decompress the packages, and install the software.
The kunpeng-dc-devel and kunpeng-dc software packages are dependent on each other. You must install the kunpeng-dc software package before installing the kunpeng-dc-devel software package. Before uninstalling the kunpeng-dc software package, ensure that the kunpeng-dc-devel software package has been uninstalled.
Ensure that kunpeng-dc and kunpeng-dc-devel software packages are of the same version.
