The C++ sources can be compiled using the GCC compiler 3.x or 4.x series. It is known to work on most Linux distributions and on Windows using MinGW+MSys [1] and Cygwin [2]. The provided archive contains Eclipse [3] project files which allow you to develop and build the code using the Eclipse CDT IDE. You can also compile the sources manually using the included makefile:
tar -zxf deborah.tgz cd deborah/Release make
By default, the executable will be stored into the ./Release subdirectory. Please check that the compiler options used in the Makefile are suitable for your system, especially the optimization flags -march=xxx and -Ox. The ./Release directory contains a Makefile which will generate a binary tuned for Intel i686-class processors and level-two code optimizations (-O2).
Usage
You can obtain the inline help by typing:
./deborah --help
The distribution archive contains a few sample tandem configuration files which can be found into the ./scenarios directory. You can give Deborah a quick try with:
./deborah scenarios/tree-k3-l2.conf --lb --ludb
This will compute both LUDB and Lower Bound on a balanced tree having K=3 and L=2. Tandem configurations can be written as text files using a very simple syntax; just take a look at the samples provided.
Changelog
v0.91 (September 16, 2010):
- Implemented Single Tandem Analysis (STA) method to compute LUDB in non-nested topologies.
- Accurate performance timing and bug fixes
v0.90 (July 31, 2009):
- Added support for LUDB analysis of non-nested tandems
- Minor optimizations and bug fixes in LUDB-related code
v0.85 (October 23, 2008):
- Initial Deborah release
