This little code snipped messure the performance for adios write/read and verify the results.

compile no transform: mpic++ -std=c++11 main.cpp -I$ADIOS_ROOT/include -L$MPI_ROOT/lib -L$ADIOS_ROOT/lib   -ladios -ladiosread -L$LZ4_ROOT/lib -llz4 -lz -DADIOS_TRANSFORM=\"none\"

compile with LZ4 transform: mpic++ -std=c++11 main.cpp -I$ADIOS_ROOT/include -L$MPI_ROOT/lib -L$ADIOS_ROOT/lib   -ladios -ladiosread -L$LZ4_ROOT/lib -llz4 -lz -DADIOS_TRANSFORM=\"lz4:threshold=2048,lvl=9\"

virtual python environment [matplotlib, no X-window]
Solution to solve that matplot lib not show any X window in a virtual python environment
follow the [embedded guid](https://github.com/ComputationalRadiationPhysics/picongpu/blob/dev/src/picongpu/submit/titan-ornl/pythonOnRhea.profile.example)
- cd ~/lib
- mkdir -p python-venv
- cd python-venv
- virtualenv hypnos2.7.10
- source ~/lib/python-venv/hypnos/bin/activate
- which pip
