Test comments


Tests 2, 4, as well as standard MP4 benchmark were run in multithreaded mode, other tests were run in standard parallel mode using dynamic load balancing over p2p interface. Wall clock times are given on master node in seconds.


We are grateful to Andrey Kudryavtsev for providing us access to this system and technical support.
