neoParSA is a highly modularized parallel and serial simulated annealing library in C++. It is designed to be both easy to use and easy to extend.

1. Dependencies
2. Build
3. Usage

neoParSA library proper requires an implementation of MPI version 2.0 or above. Common ones are

• MPICH
• Open MPI

Intel MPI Library or other vender specific MPI implementations also work.

In addition to MPI, neoParSA library propery also requires

• [CMake] >=2.8.0
• [Boost] >=1.56 [CMake]: https://cmake.org/ [Boost]: http://www.boost.org/ The pattern formation model test problem fly requires an extra library
• [GNU Scientific Library][gsl] [gsl]: http://www.gnu.org/software/gsl/

neoParSA uses CMake as a build system to allows cross platform, out of source builds with flexible build options. It is always recommended to compile the library in a separate directory. Suppose the source files are in the directory neoParSA, it is recommended to create a subdirectory build inside.

$ cd neoParSA
$ mkdir build

If all dependencies are in their usual location, the build can be configured without extra options.

$ cd build
$ cmake ..

You can specify options to for configuration:

$ CC=icc CXX=icpc cmake -D CMAKE_BUILD_TYPE=Release -D BOOST_ROOT=$HOME/boost_1_59 ..

To compile just the library, do

$ make parsa

To make the library and all the test problems, do

$ make

neoParSA requires the problem to be optimized to be enclosed in a class with the following member methods:

size_t getDimension();
double get_score();
void generateMove(int index, double theta);
void restoreMove(int index);

For parallel versions, it needs three more:

size_t getStateSize();
void serialize(void *buf);
void deserialize(void const *buf);
