+<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. |
