198<title>Choosing a userland</title>
199<body>
200
201<p>
202On PPC64, the kernel is 64-bit and the <e>userland</e> can be 32-bit or 64-bit. The
203userland is basically the applications you are running, such as
204<c>bash</c> or <c>mozilla-firefox</c>. They can be compiled and run in either
20564-bit or 32-bit modes. The Gentoo/PPC64 team provides both 32-bit and 64-bit
206userlands, so which one should you use?
207</p>
208
209<p>
210You may have heard that 64-bit applications are better, but in fact, 32-bit
211applications take up slightly less memory and often run a little bit faster than
21264-bit applications.
213</p>
214
215<p>
216You really only need 64-bit applications when you need more memory than a 32-bit
217userland allows, or if you do a lot of 64-bit number crunching. If you run
218applications that require more than 4GB of memory or you run scientific
219applications, you should choose the 64-bit userland. Otherwise, choose the
22032-bit userland, as it is recommended by the Gentoo/PPC64 developers.
221</p>
222
223<p>
224Additionally, the 32-bit userland has been available in Portage longer than the
22564-bit userland has. This means that there are more applications tested in the
22632-bit userland that just work "out of the box." Many applications compiled for
227the 64-bit userland may be just as stable as the 32-bit version, but they
228haven't been tested yet. Though testing isn't difficult to do, it can be
229annoying and time consuming if you want to use many untested 64-bit
230applications. Also, some programs just won't run in the 64-bit userland until
231their code is fixed, such as OpenOffice.
232</p>
233
234<p>
235The Gentoo/PPC64 team provides stages and Package CDs for both 32-bit and 64-bit
236userlands, so no matter which one you choose, you'll be able to successfully
237install Gentoo and get a full system up and running with minimal fuss.
