The +userland is basically the applications you are running, such as +<c>bash</c> or <c>mozilla-firefox</c>. They can be compiled and run in either +64-bit or 32-bit modes. The Gentoo/PPC64 team provides both 32-bit and 64-bit +userlands, so which one should you use? +</p> + +<p> +You may have heard that 64-bit applications are better, but in fact, 32-bit +applications take up slightly less memory and often run a little bit faster than +64-bit applications. +</p> + +<p> +You really only need 64-bit applications when you need more memory than a 32-bit +userland allows, or if you do a lot of 64-bit number crunching. If you run +applications that require more than 4GB of memory or you run scientific +applications, you should choose the 64-bit userland. Otherwise, choose the +32-bit userland, as it is recommended by the Gentoo/PPC64 developers. +</p> + +<p> +Additionally, the 32-bit userland has been available in Portage longer than the +64-bit userland has. This means that there are more applications tested in the +32-bit userland that just work "out of the box." Many applications compiled for +the 64-bit userland may be just as stable as the 32-bit version, but they +haven't been tested yet. Though testing isn't difficult to do, it can be +annoying and time consuming if you want to use many untested 64-bit +applications. Also, some programs just won't run in the 64-bit userland until +their code is fixed, such as OpenOffice. +</p> + +<p> +The Gentoo/PPC64 team provides stages and Package CDs for both 32-bit and 64-bit +userlands, so no matter which one you choose, you'll be able to successfully +install Gentoo and get a full system up and running with minimal fuss. +</p> + +</body> +</subsection> </section> <!-- STOP --> <section> -- [EMAIL PROTECTED] mailing list
