MPI-Vina: MPI based parallel implementation of Autodock Vina

MPI-Vina is an open-source parallelization of AutoDock Vina, which massively reduces the time of virtual screening by using compute clusters or network of computers. It is developed based on MPI and intended for distributed memory environment. The goal of MPI-Vina is to reduce the overall time of screening ligand data set. AutoDock Vina is the primary docking program of MPI-Vina.

In MPI-Vina, protein-ligand docking is distributed into different nodes of a computational cluster where each node performs docking of a single ligand against a target receptor. Distribution of ligand set allows docking multiple ligands in multiple nodes concurrently.

MPI-Vina reduces the overall time of doing virtual screening dramatically than the traditional virtual screening approach by using state-of-the-art parallel processing. It also reduces the magnitude and complexity of the screening problem and focuses on drug discovery and optimization efforts on the most promising leads.


Availability of any MPI implementation (e.g., Open MPI, MPICH).


  1. Convert your target receptor (i.e., protein) and all ligands into pdbqt format format (using any traditional tools).
  2. Put all the ligand files in the Ligand directory.
  3. Put your configuration file (conf.txt) and target receptor in the Vina directory.
  4. To build and run the program type ./runMpiVINA.bash in CLI (use for Gride Engine schedular). The corresponding Makefile and Shell script will do the remaining job.
  5. All output files are placed in the Output directory.
    • MpiVina.log file contains summary of the parallel procesing.
    • SortedResult file contains binding affinity of all ligands in sorted order.
    • <ligand_name>.pdbqt.pdbqt & <ligand_name>.pdbqt.txt files contain the detailed result of individual ligand.


For more details (e.g., implementation, performance, etc.), the reader is reffered to the technical report available in docs directory.
