BoincPlatforms

-BOINC defines a set of platforms (see below).
-If you want your application to exploit specific architectural features at a finer granularity,
-your application must recognize the features and branch to appropriate code.
-In other words, if you want to make a version of your application that can use the AMD 3DNow instruction set,
-don't create a new '''windows_amd_3dnow''' platform.
-Instead, make a version for the '''windows_intelx86''' platform that recognizes when it's running on a 3DNow machine,
-and branches to the appropriate code.
-
-Platforms are maintained in the '''platform''' table in the BOINC database.
-This is pre-populated with the 10 or so most common platforms.
-For coherence between projects, use only the following platforms.
-If you want to add a different platform, please [ProjectPeople contact us].
+
+You may have executables that exploit specific architectural features at a finer granularity
+than that of platform.
+For example, you may have an executable that uses AMD 3DNow instructions.
+There are two ways to arrange this:
+
+ * Use the [AppPlan application planning] mechanism to specify a class of app versions that can be sent only to hosts with particular CPU features;
+ * Make a "fat executable" that recognizes when it's running on a 3DNow machine,
+and branches to the appropriate code.
