Joh had posted an example of F# of using RK4 and showed some performance numbers comparing F# to C++ and OCaml. Don Syme had been reading too and asked if anyone on theen-USCommunityServer 2.1 SP1 (Build: 61025.2)http://blogs.msdn.com/jomo_fisher/archive/2008/09/16/f-performance-tweaking.aspx#8954257Tue, 16 Sep 2008 21:58:36 GMT91d46819-8472-40ad-a661-2c78acb4018c:8954257kfarmer<p>What?! &nbsp;You have a physical constant and no units of measure?! :)</p>http://blogs.msdn.com/jomo_fisher/archive/2008/09/16/f-performance-tweaking.aspx#8954277Tue, 16 Sep 2008 22:17:50 GMT91d46819-8472-40ad-a661-2c78acb4018c:8954277Jomo Fisher<p>Units of measure would fit nicely in this code. But, I don't know which version of the compiler Joh is using and they weren't available until 1.9.6.0. They won't affect performance anyway.</p> http://blogs.msdn.com/jomo_fisher/archive/2008/09/16/f-performance-tweaking.aspx#8955100Wed, 17 Sep 2008 11:04:28 GMT91d46819-8472-40ad-a661-2c78acb4018c:8955100brilsmurf<p>I managed to get another 20% off the RK4 time by singling out the delta/6.0 calculation in runge_kutta_4_opt.</p>http://blogs.msdn.com/jomo_fisher/archive/2008/09/16/f-performance-tweaking.aspx#8955821Wed, 17 Sep 2008 20:01:49 GMT91d46819-8472-40ad-a661-2c78acb4018c:8955821Joh<P>I'm pleased to see my experiments are attracting attention :)</P> <P>I had somehow missed the availability of structs which made me wonder how fast 3d computation could be achieved in F#.</P> <P>Good catch, brilsmurf. I would not have thought it would make such an impact.</P>http://blogs.msdn.com/jomo_fisher/archive/2008/09/16/f-performance-tweaking.aspx#8956663Thu, 18 Sep 2008 07:44:42 GMT91d46819-8472-40ad-a661-2c78acb4018c:8956663Chris Smith's completely unique view<p>This post is entirely devoted to shameless plugs and ‘Me Too’ blogging. &amp;#160; The Stack Overflow public</p>
