The success of MTL4 based on generic meta-programming, arises the question about re-visiting the efficiency of code-generation approaches, including FFC. Given that FEM can particularly benefit from major meta-programming characteristics, namely static polymorphism and loop unrolling, MTL4 demonstrates that the code-generation part can be much more efficiently replaced by inlining performed at compile-time.
What FFC and other code generators do is a form of metaprogramming, so I don't see what point you're trying to make.

Without having a concrete meta-programming implementation, it may be impossible to predict how much performance one would gain compared to FFC. However, MTL4 has been reported to be many times faster than code-generation means such as ATLAS. Based on this, are there any specific benefits in FFC code-generation which may not be covered by meta-programming? -Ali _______________________________________________ DOLFIN-dev mailing list DOLFIN-dev@xxxxxxxxxx http://www.fenics.org/mailman/listinfo/dolfin-dev
