Background:

Cellular automata models offer insights into immune system (IS) dynamics.
Small-scale simulations provide qualitative understanding, but large-scale simulations are needed for detailed analysis and model validation.

Purpose of the Study:

To present PARIMM, a highly optimized simulator for large-scale immune system response simulations.
To enable simulations involving millions of cells with complex interactions.

Main Methods:

Developed a parallel processing simulator (PARIMM) for immune system dynamics.
Optimized data structures and I/O for reduced memory and disk space requirements.
Integrated simulation of T killer cell-mediated responses alongside humoral immunity.

Main Results:

PARIMM supports large-scale simulations of millions of cells with high complexity.
Optimizations significantly reduce memory and disk space demands.
The simulator now models both humoral and cellular immune reactions.

Conclusions:

PARIMM is a highly complete and efficient tool for advanced immune system simulation.
Facilitates in-depth analysis and validation of complex immune response models.
Advances computational immunology research through its comprehensive simulation capabilities.
