there's probably many ways, but here's three: at compile time, you will see the following message if tcmalloc is not enabled: "Tip: install tcmalloc for faster threading. See BUILD-INSTRUCTIONS.txt for more information." you can also use '--without-tcmalloc' to disable tcmalloc and compare speed to a binary that is compiled with tcmalloc. If you use profiling tools (such as 'perf'), you can see which malloc is being called. 'perf top' shows me this line, among others: 1.75% moses_chart moses [.] tcmalloc::ThreadCache::ReleaseToCentralCache(tcmalloc::ThreadCache::FreeList*, unsigned long, int _______________________________________________ Moses-support mailing list Moses-support@mit.edu http://mailman.mit.edu/mailman/listinfo/moses-support
