SEP Radio: Living in a 64-bit world: making apps work with 64-bit OSes

Windows developers Anna-Jayne Metcalfe, Inbar Gazit & Sushil Sapre talk about their experiences with developing software for 64-bit OSes. In a world where 64-bit OSes have become standard our guests Anna-Jayne Metcalfe, Inbar Gazit & Sushil Sapre talk about their experiences with developing software that not only runs well in this increasingly common environment, but can take advantage of it as well. Tune in for advice on the issues to consider for making your apps compatible with 64-bit OSes, and hands-on advice in making the transition.

  1. I tend to disagree.

    Obviously the primary (only?) system you gentlemen have been talking about is the MS Windows. It's pretty obvious that as long as JIT is concerned there's not too much you could expect.

    You look at the '32 vs 64 bit OS' case through the glasses of addressable memory range, and this range only, which is pretty much the primary flaw of the discussion. There's more than '64 bit address bus', come on! How about the registers? what about calculations, that do not need to be carried through complex multiple assembly instructions just because 32 bit is clearly not enough?

    maybe it's a good idea to at least look at the benchmarks - just check up '32bit vs 64bit benchmark' - and at least check up the 'bars', like those in this article:

    i am terribly sorry, but this article was very much focused on .NET technology, which has pretty much nothing to do with processor architecture... maybe except for the often mentioned addressable memory range.

    Keeping my fingers crossed for future episodes,
