F# is superficially similar to OCaml, most notably its OCaml-like syntax, but there are some quite major differences: http://www.strangelights.com/fsharp/wiki/default.aspx/FSharpWiki/FSharpAndOCaml.html > why do you need HLVM? Good question. I saw these important advantages realized in F# by Microsoft and wanted to bring those benefits to the OCaml/Linux world. There is no "need" to do so unless you refuse to use Windows and I am happily using Windows now. Moreover, the libraries available under Linux are dire in comparison to .NET. Hence I am no longer really motivated to work on HLVM. F# is a lot more fun and a lot more profitable. :-) > Is F# using the LLVM? No. F# is Microsoft's new programming language for .NET. > or is it executing natively compiled code? Yes. The F# compiler generates .NET assemblies containing CIL (Common Intermediate Language) that the CLR (Common Language Run-time) then JIT compiles the CIL to native code: http://en.wikipedia.org/wiki/File:CLR_diag.svg This is true of the interactive F# REPL as well as compiled binaries. > From what I have garnered today in a quick scan of JIT docs, it > appears that JIT cannot compete yet with native code.

The timings I posted show JIT-compiled F# solving your problem orders of magnitude faster than native-code compiled with ocamlopt. OCaml's interpreted bytecode is even slower than its compiled native code, of course. I don't know how fast other native-code compiled languages like C, C++ and Fortran are in comparison except that some of my numerical F# code outperform's Intel's vendor-tuned Fortran running on Intel hardware. -- Dr Jon Harrop, Flying Frog Consultancy Ltd. http://www.ffconsultancy.com/?e _______________________________________________ Caml-list mailing list.
