Re: Note on optimized compilation / optimized coding / profiling results

 



Bruno, what do you use to measure time of execution? Small.xyz and
TriaxialTest or something else?

time ./yade-svn1258 -n -- -f /home/bruno/YADE/data/scene_test.xml -v 100 -p -m 40000

Where scene_test.xml is a 4000 particles triaxial test, with enabled autoCompressionActivation, a low strain rate (strainRate="0.01"), and a strict equilibrium criterion (StabilityCriterion="0.001"). Everything else is default IIRC.
I send you that scene.xml.

"time" gives this sort of result :

real    13m10.555s
user    12m33.367s
sys     0m4.988s

You must consider "user" time, wich can differ a lot from "real" in case you do something else during computation.
