+- AMD: the number of cores in a processor. On a system where cores areBoris, this documentation will help tremendously. In just this line of code:
+clustered in groups of 2, 4 or more in compute units, this variable
+denotes the number of*compute units* on the node.
+In both cases, the number of scheduling threads is computed by doing:
+ x86_max_cores * smp_num_siblings
+* smp_num_siblings: the number of siblings in a core. On AMD with
+compute units, this number is the number of compute unit siblings,
+i.e., compute unit cores in a single compute unit, according to their
