GitLab

- Flushing the output explicitly.

- The memory alignment was adjusted.
- The progress output is now flushed.

- Fixed 'svn export' in download.py.

- Added PDF files from ftp server.
- Added a python script that can be used to download test data on demand.

- A directory "tools/" was added. It includes programs that can be used to display the results created by EasyWave.
- A directory "tests/" was added that contains some python scripts for testing different versions of EasyWave.

This is an alpha version that dynamically creates a subset of the input grid according to the source location.
The number of steps that are necessary to run a complete simulation is hardcoded for now. Maybe there is a better
approach.

This feature is needed to use EasyWave from the web where a user can specify any source location and we have to
choose the right grid to answer his request.

- Run *Update- and *Boundary-kernels in different streams and thus concurrently.

- Fixed some indexing issues in kernel WaveBoundary (memory accesses of 1D-Arrays were not 0-based).
- Closed small memory leaks caused by cuda-calls.

The memory layout should change to map the grid contents directly.
The pre-calculation of some constant arrays could be done once for each grid.

- Added some time measurement and a verbose mode that can be enabled with "-verbose".
