Google Code Jam Runner

This is a wrapper library for C++ solutions to Google Code Jam problems. This wrapper

• takes care of test cases
• let's you run your solution on a specific set of test cases (with the -o flag)
• tells you on which test case your solution crashed (planned feature)
• gives you a nice overview of the progress your solution is making through the test cases
• allows you to spawn multiple processes, even on multiple machines, and distribute the test cases among them (with the -d flag and a simple config file)

Usage

Just copy gcj.h, include.h, and template.cpp to a directory where your solutions are located.

To start coding a new solution, create a new file with the same contents as template.cpp, and follow the TODO's.

To run the program, start by compiling your solution like usually (g++ -Wall -O2 solution.cpp -o run). Then run the program, and pass a command line argument specifying a test file to run. For example, ./run test-file.in > test-file.out.

Distributing test cases

Create a file dist.conf with one or more lines. Each line contains a hostname (or any kind of hostname string that the ssh and scp commands accept), followed by the number of jobs that should be run on that machine. Note that you should be able to ssh into the given hostnames without having to specify a password. Then you can run an input file in distributed mode by calling ./run -d dist.conf test-file.in > test-file.out.
