> I think BLITZ++ used to have some very good performance comparisons
with<br />&gt; Fortran IIRC. (What ever happend to BLITZ++? Is it
dead?)<br /><br />yes it does, I used it and the invaluable material from
Todd to build my own ET based container library. I wish I knew what
happened to Blitz indeed as I think its code base - while verbose and
untidy - was very interesting<br /><br /> &gt; I am actually interested
about the iterators performance in multi-array<br />&gt; too, since their
iterators seem to just wrap indexes.  That _seems_ like it<br />&gt; would
be bad, but Idunno.<br /><br />iterator or pointer almost leads to the
same performances (ina 5 to 10% margin maybe). <br />The real error people
keep doing is performing test on huge dataset without any cache friendly
algorithm
