Multi-threading Optimisations

Update the main computational classes to split up work into separate threads. Should improve performance when running on a single computer.

• BSimChemicalField [Done] - Update class to use worker threads when calculating the new diffusion field.
• BSimCollisionPhysics [Done] - Update class to use worker threads when calculating the force matrix.
• BSimCollisionPhysics - Update class to use multithread the call to the runLogic method on each bacterium.

Batch Processing

We need to be able to run batch runs of simulations to get enough results for statistical analysis.

• Parameter File Definition - We need a simple text file defined that allows for all the parameters in the simulation and sets of bacteria, particles and boundaries defined. It should look something like the example below with each line either giving a parameter definition or BSimObject creation details.

Viscosity: 0.0001
Dt: 0.01
CreateBacterium: 10, 10, 3.7, 50
CreateRandomBacteriaSet: 0, 0, 500, 600, 3.7, 50
...

• BSimBatch - Class to read the parameter files and run a set number of simulations, outputting videos and a data file of particle movement.
• Blue Crystal Accounts - Contact university about getting accounts to run some larger scale simulations
• Output Filters - Create new classes that can be attached to a simulation scene, allowing for information about the scene be output, e.g. in the form of text based or movie files. This ties in with the parameters that need to be monitored for the statistical analysis.

BSim Simulations

• Define Simulation Process - Ensure that the full end-to-end simulation setup and execution process is understood. Define the inputs, parameters that can be altered, and output required to calculate useful statistics for comparison. As many simulations will be run we want to make sure that problems will not arise during the runs. This should be placed on the wiki under the stochastic agent based model section.
• Specify Simulations - We need a list of all important simulations that need to be run to understand the effect various parameters have on the designs stability and viability. A list should be developed on the wiki giving a short description of the run, the parameter ranges, statistical analysis to be performed, hypothesis, actual outcome after the run and data files/example video.
• Run the simulations - Work through the previous list running the simulation sets.
