Schnek Documentation

Schnek is a C++ library that supports the development of large parallel simulation codes, originally intended for physics applications. The objective of the library to keep the user code simple while allowing flexibility and performance. The library is intended to be compatible with most *nix flavours. Schnek is heavily reliant of the Boost C++ library. In most cases it will also be compiled with support for MPI and HDF5, but it can run without these.
