I'm curious what kind of application you are referring to and where you get that impression. We are always looking for examples where we don't get good performance, so we can optimize, so I'd love to hear your experiences.
- walshemj 12y agowell I was going off stack overflow http://stackoverflow.com/questions/20613817/julia-julia-lang-performance-compared-to-fortran-and-python http://stackoverflow.com/questions/20613817/julia-julia-lang... where even with hand tuning the Julia code its a lot slower than Fortran. I as thinking of large scale CFD work ie simulating two-phase flow in a nuclear reactor or a simulation of airflow over aero systems - which is where I suspect that job I mentioned is based. Must have a look at Julia after I have finished teaching myself Java (Spit!) for hadoop
- KenoFischer 12y agoOk, looking at the code is seems like you could probably get another 2x by switching to views rather than slices which will be the default sometime in the julia 0.4 timeframe. That would probably put julia perforamance at 1.2-1.5x Fortran, which while there of course is always more optimizations to be done is at least pretty good.
