Re: [Boost-users] [multi-array] Performance? Difference from GIL or uBLAS?

I think BLITZ++ used to have some very good performance comparisons with Fortran IIRC. (What ever happend to BLITZ++? Is it dead?)

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

I am actually interested about the iterators performance in multi-array too, since their iterators seem to just wrap indexes. That _seems_ like it would be bad, but Idunno.

iterator or pointer almost leads to the same performances (ina 5 to 10% margin maybe). The real error people keep doing is performing test on huge dataset without any cache friendly algorithm
