Measurement Software on iCOD Systems

iCOD systems inherently have fewer active processors than the total number of processors in the system. This fundamental difference between the number of active processors and the total number of processors can cause some processor measurement products and utilities to report incorrect information. Additionally, when a processor is dynamically activated, some software products must recognize the change in the number of active processors in order to report correct processor related information.

The iCOD system behavior described above along with the associated system call changes described in the previous section (“iCOD and pstat, pstat_getdynamic, and mpctl System Calls”) requires close examination of and possible changes to measurement related software to ensure they work properly on iCOD systems. Some non-measurement applications may also be impacted.

HP’s OpenView measurement software and some HP-UX commands were modified to work properly on iCOD systems. For example, the HP-UX commands top and sar were modified in order to report correct information on iCOD systems.

OpenView Measurement Products

OpenView measurement products, such as MeasureWare and GlancePlus, must be version C.02.60 or later to provide correct processor measurements. OpenView measurement products, version C.02.60 or later, behave correctly on iCOD systems. Earlier versions of the OpenView measurement products do not work correctly on iCOD systems.

On Superdome Systems

On Superdome systems HP recommends updating to the GlancePlus Pak version C.03.20 or later.

Other Measurement Software

Please check with your measurement software vendor to ensure their software works properly on iCOD systems and update the measurement software versions as needed.
