Difference from the implementation of mmcv.runner.parallel_test:

  • The new implementation uses mmddp, and there can only be one process on each gpu, while parallel_test supports multiple processes per gpu.
  • The speed and gpu usage is much higher than parallel_test.

This PR is also related to #577. SyncBN cannot work with original parallel_test but should work well with mmddp.
