UFLACS - UFL Analyser and Compiler System

Description

Uflacs, the UFL Analyser and Compiler System, is a collection of algorithms for processing symbolic UFL forms and expressions. The main feature is efficient translation of tensor intensive symbolic expressions into a low level expression representation and C++ code.

Testing

To run unittests of generated C++ code you need the Google C++ Testing Framework:

https://code.google.com/p/googletest/

To run unit tests with output to screen:

cd tests/ && ./test.sh

To run unit tests with output to log files (for batch runs):

cd tests/ && ./test.py

Installing

Either install to default python location as root:

sudo python setup.py install

Or install to your own python path directory:

python setup.py install --prefix=/path/to/my/own/site-packages

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
