Evaluation of Container Virtualized MEGADOCK System in Distributed Computing Environment

SIGBIO49 @ Japan Advanced Institute of Science and Technology

We evaluate the performance of MEGADOCK system using container virtualization technology in distributed computing environment on cloud.
MEGADOCK is a Protein-Protein-Interaction Prediction System for heterogeneous supercomputers.
We choosed Docker as a container virtualization technology for Linux container implementation and evaluated parallel execution performance while increasing the number of virtual machines.
