Special thanks to Xiaowei Zhu and many for their work Gemini[1]. Several basic utility functions in Plato is derived from Gemini, the design principle of some dual-mode based algorithms in Plato is also heavily influenced by Gemini's dualmode-engine. Thanks to Ke Yang and many for their work KnightKing[2] which served as foundation of plato's walk-engine.


To simplify installation, Plato currently downloads and builds most of its required dependencies by calling following commands. You should call it at least once before any build operations.

# install compile dependencies.
sudo ./docker/
# download and build staticlly linked libraries.
./ distclean && ./ install


Plato was developed and tested on x86_64 cluster and Centos 7.0. Theoretically, it can be ported to other Linux distribution easily.

Test && Build







  1. A cluster which can submit MPI programs(Hydra is a feasible solution).
  2. An accessible HDFS where Plato can find its input and put output on it.

A sample submit script was locate in here, modify it based on your cluster's environment and run.
