Download, compile and install lossy checkpointing (as easy as 1,2,3)

1. git clone https://github.com/dingwentao/lossy-checkpoint.git
2. mkdir lossy-checkpoint/build && cd lossy-checkpoint/build
3. cmake -DCMAKE_INSTALL_PREFIX:PATH=[installation path] .. && make all install

Intel and GCC

For the case that both Intel and GCC compilers are installed, please configure using:
cmake -C ../intel.cmake -DCMAKE_INSTALL_PREFIX:PATH=[installation path] ..

---

OpenSSL

To use the built-in MD5 rather than OpenSSL, please configure using:
cmake -DNO_OPENSSL=true -DCMAKE_INSTALL_PREFIX:[installation path] ..

Cray System

Lossy checkpointing library works on Cray system with these modules
GNU environment:
module load gcc/5.3.0 CMake/3.6.2 craype/2.5.8 cray-mpich/7.5.0 PrgEnv-gnu/6.0.3
export CRAY_CPU_TARGET=x86-64
export CRAYPE_LINK_TYPE=dynamic
Flag for CMake: -CMAKE_SYSTEM_NAME=CrayLinuxEnvironment

Intel environment:
module load intel/17.0.1.132 CMake/3.6.2 craype/2.5.8 cray-mpich/7.5.0 PrgEnv-intel/6.0.3
export CRAY_CPU_TARGET=x86-64
export CRAYPE_LINK_TYPE=dynamic
Flag for CMake: -CMAKE_SYSTEM_NAME=CrayLinuxEnvironment

The most important is CMake version: the newer the better.
