42 +<title>Choosing a userland</title>
43 +<body>
44 +
45 +<p>
46 +On PPC64, the kernel is 64-bit and the <e>userland</e> can be 32-bit or 64-bit. The
47 +userland is basically the applications you are running, such as
48 +<c>bash</c> or <c>mozilla-firefox</c>. They can be compiled and run in either
49 +64-bit or 32-bit modes. The Gentoo/PPC64 team provides both 32-bit and 64-bit
50 +userlands, so which one should you use?
51 +</p>
52 +
53 +<p>
54 +You may have heard that 64-bit applications are better, but in fact, 32-bit
55 +applications take up slightly less memory and often run a little bit faster than
56 +64-bit applications.
57 +</p>
58 +
59 +<p>
60 +You really only need 64-bit applications when you need more memory than a 32-bit
61 +userland allows, or if you do a lot of 64-bit number crunching. If you run
62 +applications that require more than 4GB of memory or you run scientific
63 +applications, you should choose the 64-bit userland. Otherwise, choose the
64 +32-bit userland, as it is recommended by the Gentoo/PPC64 developers.
65 +</p>
66 +
67 +<p>
68 +Additionally, the 32-bit userland has been available in Portage longer than the
69 +64-bit userland has. This means that there are more applications tested in the
70 +32-bit userland that just work "out of the box." Many applications compiled for
71 +the 64-bit userland may be just as stable as the 32-bit version, but they
72 +haven't been tested yet. Though testing isn't difficult to do, it can be
73 +annoying and time consuming if you want to use many untested 64-bit
74 +applications. Also, some programs just won't run in the 64-bit userland until
75 +their code is fixed, such as OpenOffice.
76 +</p>
77 +
78 +<p>
79 +The Gentoo/PPC64 team provides stages and Package CDs for both 32-bit and 64-bit
80 +userlands, so no matter which one you choose, you'll be able to successfully
81 +install Gentoo and get a full system up and running with minimal fuss.
