Hello! (I've been out of e-mail range for a week) I've posted some results on the wiki (and I actually have MTL4 :-) ) where I just show total assembly times with and without optimization turned on. MTL4 responds quite well to -O3 (unlike uBLAS).
As far as the MTL4 backend goes, I have implemented and tested almost all the operators and member functions. We are running into some quirks with namespaces in MTL4 which Peter G is going to sort out. Also, there is a bug somewhere in the version of the backend currently in place -- so please don't use it without manually initializing matrix dimensions. I will sort this out in a day or two and then have a bundle ready that finalizes the MTL4 backend. The performance results have been encouraging enough to keep me (and Garth) motivated to get this backend ready for "real" use. /Dag Ilmar Wilbers wrote: > Yeah, that would be the case for me as well.
