Installing Dependencies

To install OmniOperator locally, install the LLVM and jemalloc dependency packages on the management node and all compute nodes. You can install the dependencies either by downloading pre-compiled SO files or by compiling source code.

Installing Dependencies (By Downloading Pre-compiled SO Files)

Installing LLVM and jemalloc

The Dependency_library.zip package contains the Dependency_library_openeuler.zip and Dependency_library_centos.zip subpackages, which are used for openEuler and CentOS, respectively. The following uses openEuler as an example. To install OmniOperator on CentOS, replace Dependency_library_openeuler.zip in the following commands with Dependency_library_centos.zip.

  1. Create an /opt/omni-operator/ directory on the management and compute nodes as the root directory for installing OmniOperator. Then go to the directory.
    1

3
    mkdir /opt/omni-operator
cd /opt/omni-operator
rm -rf Dependency_library_*.zip
  2. Upload the Dependency_library packages (Dependency_library.zip and Dependency_library.z01) obtained from Obtaining Software Packages to the /opt/omni-operator/ directory and decompress them.

2
    zip -F Dependency_library.zip --out Dependency_library_complete.zip
unzip Dependency_library_complete.zip
  3. Create an /opt/omni-operator/lib directory, and decompress the libLLVM-15.so and libjemalloc.so.2 subpackages in Dependency_library_openeuler.zip to the /opt/omni-operator/lib directory.

    mkdir lib
rm -rf  /opt/omni-operator/lib/libjemalloc.so.2
rm -rf  /opt/omni-operator/lib/libLLVM-15.so
unzip -d /opt/omni-operator/lib -o Dependency_library_openeuler.zip libLLVM-15.so libjemalloc.so.2

The /opt/omni-operator and /opt/omni-operator/lib directories can be customized.

Install Dependencies (By Compiling Source Code)

Installing LLVM

  1. Download https://github.com/llvm/llvm-project/archive/refs/tags/llvmorg-15.0.4.tar.gz, create an /opt/omni-operator directory on the management and compute nodes as the root directory for installing OmniOperator, go to the directory, and upload the package to /opt/omni-operator.

    mkdir /opt/omni-operator
cd /opt/omni-operator
tar zxvf llvm-project-llvmorg-15.0.4.tar.gz
mv llvm-project-llvmorg-15.0.4 llvm
cd llvm
mkdir build
  2. Go to the build directory, and compile and install LLVM.

    cd ./build
cmake -DCMAKE_INSTALL_PREFIX=/opt/omni-operator/llvm -DCMAKE_BUILD_TYPE=Release -DLLVM_BUILD_LLVM_DYLIB=true -DLLVM_ENABLE_PROJECTS="clang" -G "Unix Makefiles" ../llvm
make -j4
make install
  3. Create a lib directory in /opt/omni-operator and copy /opt/omni-operator/llvm/lib/libLLVM-15.so to /opt/omni-operator/lib.
    1
2
    mkdir /opt/omni-operator/lib
cp /opt/omni-operator/llvm/lib/libLLVM-15.so /opt/omni-operator/lib/

The /opt/omni-operator, /opt/omni-operator/llvm, and /opt/omni-operator/lib directories can be customized.

Installing jemalloc

  1. Download https://github.com/jemalloc/jemalloc/archive/refs/tags/5.3.0.tar.gz and upload it to the management and compute nodes.
    1
2
3
    cd /opt/omni-operator/
tar zxvf jemalloc-5.3.0.tar.gz
mv jemalloc-5.3.0 jemalloc

    The /opt/omni-operator/jemalloc directory can be customized.

  2. Go to the jemalloc directory, run the script, and install the generated file.
    1
2
3
    cd jemalloc
./autogen.sh --disable-initial-exec-tls
make –j2
  3. Copy /opt/omni-operator/jemalloc/lib/libjemalloc.so.2 to the /opt/omni-operator/lib directory.
    1
    cp /opt/omni-operator/jemalloc/lib/libjemalloc.so.2 /opt/omni-operator/lib/
