MEGADOCK

MEGADOCK predicts protein–protein complex structures and performs large-scale interactome docking using FFT-based algorithms for structural bioinformatics analyses.

Key Features:

• FFT-Based Docking: Employs Fast Fourier Transform (FFT) algorithms for efficient exhaustive evaluation of docking scores.
• Scalable Performance: Demonstrates over 97% strong scaling on heterogeneous supercomputing environments for large-scale computations.
• Heterogeneous Computing Utilization: Utilizes OpenMPI for distributed computing and NVIDIA CUDA (version 5.0 or later) for GPU acceleration on heterogeneous supercomputers.
• All-to-all Interactome Docking: Performs all-to-all protein–protein interaction prediction to support interactome-scale analyses.

Scientific Applications:

• Interactome Analysis: Enables interactome-scale prediction of pairwise protein–protein interactions for structural network mapping.
• Structural Bioinformatics: Supports investigation of molecular mechanisms and complex biological networks through predicted protein–protein complex models.

Methodology:

The method integrates FFT-based docking algorithms with parallelization via OpenMPI and GPU acceleration using NVIDIA CUDA (version 5.0 or later) on heterogeneous supercomputers.
