ZisaTimeStepping

ZisaTimeStepping is provides funcionality related to time stepping. In HPC applications often the problem is solved by taking small steps forward in time. This library provides a progress bar and a TimeKeeper which keeps track of the current simulation time, as well as classes to decide when the simulation should be written to file or (eventually) stopped.

Note: This library does not implement any ODE solvers.

Quickstart

Start by cloning the repository

$ git clone https://github.com/1uc/ZisaTimeStepping.git

and change into the newly created directory. Then proceed to install the dependencies:

$ bin/install_dir.sh COMPILER DIRECTORY DEPENDENCY_FLAGS

they will be placed into a subdirectory of DIRECTORY and print part of the CMake command needed to include the dependencies. COMPILER must be replaced with the compiler you want to use. The available DEPENDENCY_FLAGS are

--zisa_has_mpi={0,1} to request MPI.
--zisa_has_hdf5={0,1} to request HDF5 for writing arrays.
--zisa_has_netcdf={0,1} to request NetCDF for writing arrays.
--zisa_has_cuda={0,1} to request CUDA (experimental).

If this worked continue by running the cmake command and compiling the library. Take a look at the project specific flags for CMake if you want to modify something. If this didn't work, it's not going to be a quick start. Please read Dependencies and then Building.
