Hi Liling,
I did both on AWS for my WMT2016 en-ru/ru-en systems. No problems with
that. What would be the problems you ran in?

Dear Hieu,

Please see the answers below.

Can you clarify a few things for me.

We run experiments on the same MT04 Chinese text as we tuned the system.
The text consists of 1788 unique sentences and 49582 tokens.


> 2. Are the model sizes you quoted the gzipped text files or unzipped, or
> the model size as it is when loaded into memory?
>

This is the plain text models as stored on the hard drive.


> 3. Can you please reformat this graph

The plot is attached, but this one is not about words per second, it shows
the decoding run-times (as in the link you sent). The non-log scale plot,
as you will see, is hard to read. I also attach the plain data files for
moses and moses2 with the column values as follows:

number of threads | average runtime decoding + model loading | standard
deviation | average runtime model loading | standard deviation
