Speed up with compiler optimization
SimonSuster opened this issue · comments
In case anyone is clustering large datasets:
in my experiments (40M corpus and NofClusters=1000), turning on compiler optimization with "-O3" yields speed-ups of around 3.
I changed the following lines in my Makefile:
wcluster: $(files)
g++ -Wall -g -O3 -o wcluster $(files)
%.o: %.cc
g++ -Wall -g -O3 -o $@ -c $<
I'm surprised I didn't have it in there before. It's added now - thanks
for the note!
