| 965 The kernel will try to allocate memory used by a CPU on the 966 local memory controller of the CPU and add some more 967 NUMA awareness to the kernel. 968 | 962 The kernel will try to allocate memory used by a CPU on the 963 local memory controller of the CPU and add some more 964 NUMA awareness to the kernel. 965 |
| 969 For 32-bit this is currently highly experimental and should be only 970 used for kernel development. It might also cause boot failures. 971 For 64-bit this is recommended on all multiprocessor Opteron systems. 972 If the system is EM64T, you should say N unless your system is 973 EM64T NUMA. | 966 For 64-bit this is recommended if the system is Intel Core 7i 967 (or later), AMD Opteron, or EM64T NUMA. |
| 974 | 968 |
| 969 For 32-bit this is only needed on (rare) 32-bit-only platforms 970 that support NUMA topologies, such as NUMAQ / Summit, or if you 971 boot a 32-bit kernel on a 64-bit NUMA platform. 972 973 Otherwise, you should say N. 974 |
