Simultaneous Multithreading (SMT) combiner¶
Combiner for Simultaneous Multithreading (SMT). It uses the results of the following parsers:
insights.parsers.smt.CpuCoreOnline
,
insights.parsers.smt.CpuSiblings
.
-
class
insights.combiners.smt.
CpuTopology
(cpu_online, cpu_siblings)[source]¶ Bases:
object
Class for collecting the online/siblings status for all CPU cores.
Sample output of the
CpuCoreOnline
parser is:[[Core 0: Online], [Core 1: Online], [Core 2: Online], [Core 3: Online]]
Sample output of the
CpuSiblings
parser is:[[Core 0 Siblings: [0, 2]], [Core 1 Siblings: [1, 3]], [Core 2 Siblings: [0, 2]], [Core 3 Siblings: [1, 3]]]
-
cores
¶ List of all cores.
Type: list of dictionaries
-
all_solitary
¶ True, if hyperthreading is not used.
Type: bool
Examples
>>> type(cpu_topology) <class 'insights.combiners.smt.CpuTopology'> >>> cpu_topology.cores == [{'online': True, 'siblings': [0, 2]}, {'online': True, 'siblings': [1, 3]}, {'online': True, 'siblings': [0, 2]}, {'online': True, 'siblings': [1, 3]}] True >>> cpu_topology.all_solitary False
