Re: language pack #1

[John Hewitt]

Quick further note -- I already had $JOSHUA set to a different directory,
so initially all the lookups were failing.

It's possible current users of JOSHUA will as well when they download new
language packs. This should be an obvious and quick fix for the user, but I
don't know if there's something we could do in the name of making it even
clearer. (Potentially checking whether $JOSHUA is the same as $PWD after
the directory change in prepare.sh, and printing a warning if it's not?)

Re: moses2 vs. joshua

[Matt Post]

Hi folks,

Sorry this took so long, long story. But the four models that Hieu shared with 
me are ready. You can download them here; they're each about 15–20 GB.

  http://cs.jhu.edu/~post/files/joshua-hiero-ar-en.tbz 

  http://cs.jhu.edu/~post/files/joshua-phrase-ar-en.tbz 

  http://cs.jhu.edu/~post/files/joshua-hiero-ru-en.tbz 

  http://cs.jhu.edu/~post/files/joshua-hiero-ru-en.tbz

It'd be great if someone could test them on a machine with lots of cores, to 
see how things scale.

 I'll ask Hieu; I don't anticipate any problems. One potential problem is
 that that models occupy about 15--20 GB; do you think Jenkins would host
 this?
