What model of parallelism NVIDIA fork uses? Is there any documentation or paper about it?
How much speed improvement we may to expect using "-gpus all" switch for 2 and 4 GPUs?

We merged this pull request early - BVLC#2114. BVLC made some modifications and merged this pull request instead - BVLC#2903. There's a lot of info in both of those discussions which should answer your questions.

So I can use https:/BVLC/caffe/tree/parallel branch also with "-gpus all" switch ?

You don't need the parallel branch. BVLC#2903 is merged into the master branch.
