class %SYSTEM.CPU
extends %RegisteredObject, %SYSTEM.Help
This class holds information about available processors.
The number of threads (virtual or logical cpus), cores
and chips always reflect the situation in the current
partition or processor set.
• property Arch
as %String;
Architecture, eg: x86, Itanium, SPARC, PA-RISC
• property MHz
as %Numeric;
Clock in MHz
• property MTEnabled
as %Boolean;
Is Hardware Multi-Threading enabled?
• property MTSupported
as %Boolean;
Is Hardware Multi-Threading supported?
• property Model
as %String;
Chip model, eg: Pentium 4, POWER5
• property Vendor
as %String;
Chip vendor, eg: Intel, Sun, IBM
• property nChips
as %Numeric;
Number of chips (depends on partition configuration)
• property nCores
as %Numeric;
Number of cores (depends on partition configuration)
• property nCoresPerChip
as %Numeric;
Number of cores per chip (physical property)
• property nThreads
as %Numeric;
Number of threads (virtual or logical cpus)
• property nThreadsPerCore
as %Numeric;
Number of threads per core (physical property)
• method %OnNew()
as %Status
This callback method is invoked by the %New method to
provide notification that a new instance of an object is being created.
If this method returns an error then the object will not be created.
It is passed the arguments provided in the %New call.
When customizing this method, override the arguments with whatever variables and types you expect to receive from %New().
For example, if you're going to call %New, passing 2 arguments, %OnNew's signature could be:
Method %OnNew(dob as %Date = "", name as %Name = "") as %Status
If instead of returning a %Status code this returns an oref and this oref is a subclass of the current
class then this oref will be the one returned to the caller of %New method.
• classmethod Dump()
Display CPU information
• method Refresh()
as %Status
Force update and get new properties
