COEUS Hermes Adios Engine

This work is an adapter which connects ADIOS to Hermes through the use of the ADIOS plugins interface.

Dependencies

• Hermes: a multi-tiered I/O buffering platform.
• ADIOS2: an I/O library

ADIOS2

We have found some cases where spack failed to install ADIOS2. Below are instructions on installing ADIOS2 from source. SCSPKG is a system for organizing manually-built software and producing modulefiles for them. Instructions to install are here.

scspkg create adios2
cd $(scspkg pkg src adios2)
git clone https://github.com/ornladios/ADIOS2.git
cd ADIOS2
mkdir build
cd build
cmake ../ \
-DCMAKE_INSTALL_PREFIX=$(scspkg pkg root adios2) \
-DCMAKE_CXX_COMPILER=g++ \
-DCMAKE_C_COMPILER=gcc \
-DADIOS2_USE_SST=OFF \
-DBUILD_DOCS=ON \
-DBUILD_TESTING=ON \
-DADIOS2_BUILD_EXAMPLES=ON \
-DADIOS2_USE_MPI=ON \
-DADIOS2_USE_Derived_Variable=ON
make -j32 install
