Slurm repository build for x86_64   
===============================

The build steps must be performed on RHEL 10.0 OS node.

**Prerequisites**

If you are using RHEL subscription, enable CodeReady Builder (CRB) ::
    
     subscription-manager repos --enable codeready-builder-for-rhel-10-x86_64-rpms

Build Slurm repository for x86_64 without GPU support
=======================================================

1. Install dependencies. The following command is provided as an example: ::
      
        dnf install -y   wget git make gcc gcc-c++ rpm-build autoconf automake   python3 python3-devel perl perl-devel   readline-devel zlib-devel pam-devel dbus-devel   hwloc-devel libbpf-devel   ucx ucx-devel openmpi openmpi-devel pmix pmix-devel   jansson-devel   json-c json-c-devel   libyaml libyaml-devel   openssl-devel   mariadb-devel systemd-devel   munge munge-devel 



2. Download slurm tar file: wget, `Download <https://download.schedmd.com/slurm/slurm-25.05.2.tar.bz2>`_    

3. Run the RPM Build command. Run the following command from the directory containing the downloaded tar file. The following command is provided as an example:  ::

        rpmbuild -ta slurm-25.05.2.tar.bz2  --with pmix   --define "with_pmix --with-pmix=/usr"    --with yaml   --define "with_yaml --with-yaml"  --without hdf5   --define "without_hdf5 --without-hdf5"

After the build is completed, the RPMs are available at ``/root/rpmbuild/RPMS/x86_64/``.

    .. image:: ../../../../images/slurm_rpm_build.png

4. To verify the build before hosting, navigate to ``/root/rpmbuild/RPMS/x86_64/`` and run the following command: ::
       
        sudo rpm -ivh slurm-25.05.2-1*.x86_64.rpm 
        slurm-slurmd-25.05.2-1*.x86_64.rpm

All the required .so, cgroup_v2.so files should be available.

After you verify the build, remove the rpm packages. ::
        
        sudo dnf remove -y 'slurm'

Build Slurm repo for x86_64 with GPU support
==============================================

1. Install dependencies. The following command is provided as an example: ::
      
        dnf install -y   wget git make gcc gcc-c++ rpm-build autoconf automake   python3 python3-devel perl perl-devel   readline-devel zlib-devel pam-devel dbus-devel   hwloc-devel libbpf-devel   ucx ucx-devel openmpi openmpi-devel pmix pmix-devel   jansson-devel   json-c json-c-devel   libyaml libyaml-devel   openssl-devel   mariadb-devel systemd-devel   munge munge-devel


2. Download slurm tar file: wget, `Download <https://download.schedmd.com/slurm/slurm-25.05.2.tar.bz2>`_ 

3. Download the cuda tool kit: wget `Download <https://developer.download.nvidia.com/compute/cuda/13.0.2/local_installers/cuda_13.0.2_580.95.05_linux.run>`_

The cuda_13.0.2_580.95.05_linux.run file is downloaded.

4. After the file is downloaded, run the following command from the directory where the file is downloaded: ::
    
        bash cuda_13.0.2_580.95.05_linux.run --silent --toolkit --toolkitpath=/usr/local/cuda –override

5. Run the RPM Build command. Run the following command from the directory containing the downloaded tar file. The following command is provided as an example: ::

        rpmbuild -ta slurm-25.05.2.tar.bz2  --with pmix   --define "with_pmix --with-pmix=/usr"     --with yaml   --define "with_yaml --with-yaml"  --without hdf5   --define "without_hdf5 --without-hdf5" --with nvml   --define "_with_nvml --with-nvml=/usr/local/cuda"

After the build is completed, the RPMs are available at ``/root/rpmbuild/RPMS/x86_64/``.

6. To verify the build before hosting, navigate to ``/root/rpmbuild/RPMS/x86_64/`` and run the following command: ::

        sudo rpm -ivh slurm-25.05.2-1*.x86_64.rpm 
        slurm-slurmd-25.05.2-1*.x86_64.rpm
     

All required .so along with the gpu_nvml.so should be available.

After you verify the build, remove the rpm packages. ::
        
        sudo dnf remove -y 'slurm'
