Dilbert: Patching Peano with Hilbert

This repository contains patches for the open-source Peano framework. Peano represents a spacetree grid, using Guiseppe Peano's space-filling curve, for solvers of differential equations. Peano is a space-time code for various solver codes such as the ExaHyPE hyperbolic PDE engine.

This repository contains various patches for Peano, allowing users to put extra features in this software without going off the main development branch. Sticking to patches instead of a git branch is neccessary as peano uses Subversion for source management.

Features (so far)

  • Turn assertions on/off at run-time instead compile-time. To enable this patch, just apply patches/runtime-assertions.patch in your Peano installation.

How to use

Assume you have checked out Peano's source in some directory:

$ svn info
Path: .
Working Copy Root Path: /home/me/numrel/exahype/Engine-ExaHyPE/Peano
URL: svn://svn.code.sf.net/p/peano/code/trunk/src
Relative URL: ^/trunk/src
Repository Root: svn://svn.code.sf.net/p/peano/code
Repository UUID: aa977e5b-e928-4c84-aa66-c90e40304b12
Revision: 2762
Node Kind: directory
Schedule: normal

Last Changed Date: 2017-07-01 20:03:48 +0200 (Sat, 01 Jul 2017)

Then go and clone dilbert into a subdirectory, so you end up with something like:

    └── timing

That is, dilbert is just another directory next to peano and tarch, the two main directories of Peano. You now just can apply patches in this main installation directory. Or use any script from this directory to do that.

The name

Instead of the Peano curve, you could also use the Hilbert curve. Or just stick to the Dilbert curve.
