@@ -64,7 +64,7 @@ In addition, for some architectures, again x86 is an example, Linux supports
 the emulation of additional nodes.  For NUMA emulation, linux will carve up
 the existing nodes--or the system memory for non-NUMA platforms--into multiple
 nodes.  Each emulated node will manage a fraction of the underlying cells'
-physical memory.  NUMA emluation is useful for testing NUMA kernel and
+physical memory.  NUMA emulation is useful for testing NUMA kernel and
 application features on non-NUMA platforms, and as a sort of memory resource
 management mechanism when used together with cpusets.
