the other issue is that the phrase table for hierarchical models is 5 to
10 times larger than for pb models. So unless you have a server with a
lot of memory (probably over 20GB), the decoder will spend most of its
time doing IO lookups to find the rules.

hi,
all,
how can I speed up the decoding process in hierarchical phrase
model ?
I change the "pop-limit" from 1000 to 10 in moses.ini , but
compared with the phrase-based model, decoding a sentence with a
length of 10 is still very slow . Are there other methods to speed
up the decoding ?
the second question, in ini file :
[max-chart-span]
20
1000
the first value 20 is the max length of a span which a rule can be
applied to , but what is the second value 1000 ? Is it also a
length of span ?
