Cray XK7 (Titan) Build Example

Building on Titan is somewhat straightforward, as the software pre-requisites are already installed on the system. To set up your environment, do the following:

• Load modules

module swap PrgEnv-pgi PrgEnv-gnu
module load cmake
module load flexpath/1.12

• Set environment variables

# path to Flexpath/EVPath
PKG_CONFIG_PATH=$PKG_CONFIG_PATH:${FLEXPATH_DIR}/lib/pkgconfig

# For tracking the environment that SOS is built in:
export SOS_HOST_KNOWN_AS="\"ORNL (Titan)\""
export SOS_HOST_NODE_NAME="\"$(uname -n)\""
export SOS_HOST_DETAILED="\"$(uname -o) $(uname -r) $(uname -m)\""
export CC=cc
export CXX=CC

• Get the SOS source code:

git clone [email protected]:cdwdirect/sos_flow.git
git checkout master
mkdir build-titan
cd build-titan

• Configure with cmake:

# set an installation prefix location, or just "." for testing
sosdir=$HOME/path/to/sos/installation/prefix
cmake \
        -DCMAKE_BUILD_TYPE=RelWithDebInfo \
        -DSOS_EVPATH_EXTRA_LIBS="-lffs -ldill -lcercs_env -latl -levpath -libverbs" \
        -DCMAKE_INSTALL_PREFIX=${sosdir} \
        -DCMAKE_C_COMPILER=cc \
        -DCMAKE_CXX_COMPILER=CC \
        -DSOSD_CLOUD_SYNC_WITH_EVPATH=TRUE \
        -DSOSD_CLOUD_SYNC_WITH_MPI=FALSE \
        -DMPI_C_NO_INTERROGATE=TRUE \
        -DMPI_Fortran_COMPILER=ftn \
        -DMPI_C_COMPILER=cc \
        -DMPI_CXX_COMPILER=CC ..

• Compile!

make -j4
make install
