Now we run the following jobs on two CI systems:

1. TeamCity
   1. build and run with cmake -DWITH_GPU=ON -DWITH_TESTING=ON on GPU servers
2. TravisCI
   1. build and run with cmake -DWITH_GPU=OFF -DWITH_TESTING=ON on non-GPU servers
   2. build and deploy our documents
   3. source code style checking

where 1.i and 2.i have different entry points.

For 1.i, the entry point is described in the .travis.yml file as paddle/scripts/travis/main.sh.

The entry point of 2.i is one we recommend daily developers use -- paddle/scripts/docker/build.sh.

It would be great if we can merge them into one.

Or, can we simply remove the configuration 2.i, because it seems that 1.i has been doing a complete test?
