dTests

A python tool to distributively run GCJ/FB hacker cup testcases on several machines.

How does it work

  • First the splitter runs on the input file to split it into seprate test cases.
  • Test cases with the actuall code are sent to the server.
  • The server distributes the test cases and the actuall code to its registered nodes.
  • Each node computes the result for its testcases and sends the result back to the server
  • The server collects the results and sort them by their testcase number and sends them back to the calling script.

Installation

pip install dTests

Running dTests

  • Create new project dtests_job new project_name language
  • The only supported languages now are "cpp" and "java".
  • Open the new folder and code your splitter to read from the input.in file.
  • Between each test cases print --split--\n. The split marker can be configured in config.json file. This will split the input file into single test cases which will be distributed on the machines running.
  • Code your program file to read from stdin as if it is reading a single test cases.
  • Run the server dtests_server
  • Run one or many nodes on other machines ( or for testing on the same machine ) dtests_node --host host --port port
  • Finally run the job dtests_job run
  • Check the help of these commands for further customizations.

Sample project

This is a sample cpp project that takes input and multiply it by itself https://github.com/MohamedBassem/dTests/tree/master/samples/power2

  • The config.json file contains the project configuration. The language and the splitter syntax.
  • The splitter.cpp file contains the code that reads the input from the input.in file and splits it to single test cases.
  • The program.cpp file that reads a single test cases from stdin and computes the result.
  • To Run this project, run the server and at least one node. Then run dtests_job run in the project's directory.

TODO

  • Finding a way to pass the testcase number to the program
  • Writing Tests.
  • Making the system fault tolerant.
  • Finding a better way for splitting the input file.
  • Supporting more programming languages.
