HP Capacity Advisor 7.2 User Guide

Table 31 Units and Terminology (continued)
The amount of memory used in gigabytes (2^30 bytes).
Each sample represents an actual reading at the time the sample was taken. These measurements
are obtained and calculated in the following manner:

OpenVMS
memory utilization
The ability of an application and operating system to split processing between processors or
cores, thereby enabling parallel computing.
multithreading
Measured in Mb/s (10^6 bits, megabits per second).
Each sample represents an average reading over the past five minutes. These measurements
are obtained and calculated in the following manner:

The system-name.OTHER workload is used to account for all processes on a system that do
not match any user-defined workloads. For more information, see Workloads“Workloads” in
visualization help. On some Capacity Advisor displays, data is not available for this .OTHER
workload.
OTHER workload
Component that plugs into a processor socket. A processor can contain more than one core.processor
The packaging of one or more processors in a unit that connects to a single socket on the system
bus.
processor module
The system board socket to which a processor is attached.processor socket
A compensating factor that Capacity Advisor uses to adjust needed resources when analyzing
a move from one platform to another.
