Dear Moses,
With a hat tip to Phil Williams, you should use tcmalloc with
multi-threaded Moses.
I ran a syntactic de-en Moses system on 32 cores with pop 100. The same
probably applies to phrase-based.
Without tcmalloc:
VmPeak 42978088 kB
VmRSS 40062688 kB
real 87m17.808s
user 1816m42.584s
sys 96m15.599s
With tcmalloc:
VmPeak 38649112 kB
VmRSS 37774584 kB
real 57m21.610s
user 1452m29.026s
sys 34m41.325s
If tcmalloc is installed, Moses will link against it automatically when
built multi-threaded.
The homepage is https://gperftools.googlecode.com/. Also read Moses's
BUILD-INSTRUCTIONS.txt . Note that you should do a clean Moses compile
(-a) after installing tcmalloc.
Kenneth
