Directory and Submodule changes between V3 and V4

• Project changes between OVIS v3 and v4
  • OVIS v3 exposed LDMS, Baler, and SOS as a single project
    • Lightweight Distributed Metric Service (LDMS) – data collection, transport, and storage
    • Baler – log file pattern tagging and analysis
    • Scalable Object Store (SOS) – object store targeting HPC ingest, read, and analyses needs
  • OVIS v4 exposes LDMS, Baler, and SOS as independent projects
    • Baler is dependent on SOS
    • LDMS store-sos plugin depends on SOS
    • SOS is independent of LDMS and Baler
• Submodule confusion
  • The submodules in OVIS are no longer maintained
  • How to build with SOS without using submodules
    • Check out the desired version of SOS
      • https://github.com/ovis-hpc/sos.git
    • Configuration
      • Prerequisites for Python support
        • Python 2.7+
        • Numpy
        • Cython 0.29+
        • You can use pip to install of these
        • If you don’t want/can’t support these dependencies, use –disable-python on the configure line
      • cd sos-latest-stable
      • mkdir build
      • cd build
      • ./autogen.sh
      • cd build
      • ../configure –prefix __install-dir__ \
        • --libdir __install-dir__/lib64 \
        • -–libexecdir __install-dir__/lib64
        • [--disable-python]
    • Building SOS
      • make && sudo make install
  • How to build zap_ugni without gpcd submodule (XC/Aries only; XE/Gemini uses system gpcdr)
    • Configuration that points to pre-built gpcd libs and headers
      • --enable-ugni
      • --with--aries-libgpcd=/opt/cray/gni/default/lib64/,/opt/cray/gni/default/include/gpcd/
    • gpcd libs and headers location
      • Cray CLE 6.? UP?:
        • /opt/cray/gni/default/include/gpcd/
        • /opt/cray/gni/default/lib64/
    • Getting the gpcd code
      • https://github.com/ovis-hpc/gpcd
      • git clone [email protected]:ovis-hpc/gpcd.git gpcd
    • Building gpcd
      • Set up your environment to use the gnu compiler
      • cd gpcd
      • ./autogen.sh
      • mkdir build
      • cd build
      • ../configure --prefix=/gpcd
      • Make && make install
        • This will install libs in gpcd/lib/
        • This will install headers in gpcd/include/gpcdlocal/
      • NOTE: The local build names libs with the label “local” so you must set up symbolic links for actual lib names:
      • cd build_dir/lib
      • ln -s libgpcdlocal.so.0.0.0 libgpcd.so
      • ln -s libgpcdlocal.so.0.0.0 libgpcd.so.0
