#LASSIE 1.0.0 (beta)
LASSIE is a black-box deterministic simulator of large-scale biological systems that exploits the remarkable memory bandwidth and computational capability of modern GPUs. LASSIE accelerates the simulations of large biochemical systems (e.g., hundreds or thousands species and reactions) by distributing the calculations over a GPU's computing units. LASSIE automatically derives the system of ordinary differential equations from a reaction-based mechanistic model, defined according to the mass-action kinetics, and then exploits advanced numerical integration algorithm to deal with stiff regions of the dynamics.
HOW TO CITE LASSIE
Tangherloni A., Nobile M.S., Besozzi D., Mauri G. and Cazzaniga P.: LASSIE: Simulation of large-scale models of biochemical systems on GPUs, BMC Bioinformatics, 18(1):246, 2017
Just the Nvidia CUDA library (version 7.5 or greater).
LASSIE's binary can be compiled on any supported architecture (e.g., GNU/Linux, Microsoft Windows, Apple OS/X) using the provided scripts:
- unix.sh on GNU/Linux and Apple OS/X machines
- windows.bat on Microsoft Windows machines
The script creates a binary executable file runnable on GPUs with at least a compute capability equal to 2.0.
LASSIE is designed to be launched from the command line. The arguments are:
LASSIE input_folder output_folder
The input_folder must contain the input files describing the biochemical systems under investigation. The specification of the input files can be read at the following address:
We also created a GUI to simplify the simulation of models. To launch the GUI launch the corresponding python script:
LASSIE's GUI has the following dependencies: PyQT4, numpy, matplotlib. Experimental SBML files import can be enabled by installing the libSBML library.
