CPU Detection Help Introduction The OpenLink License Manager (oplmgr) detects the number of logical processors (historically called "CPUs" [short for "Central Processor Units"], from the time when each processor chip had only one processor core, and each core had only one thread) on which it and your OpenLink license(s) are deployed. (Virtual processor setups such as AIX micropartitions, Solaris containers, and Intel HyperThreading may cause the number of logical processors to be higher or lower than the number of physical processor cores.) You need to provide the precise number of logical processors in the host environment to obtain a functional license for that environmnt. Optimal method -- All OS All users can use our latest Web-based GUI Assistants to detect the logical processor count on the host operating system. (This detection will produce the same result as our license enforcement code.) Users who cannot or do not want to use the Web-based GUIs can generally use operating system commands and utilities to obtain the necessary information. Fallback methods -- OS-specific Windows users Use the System Information utility (Start menu --> Accessories --> System Tools --> System Information, or Start menu --> Run... --> msinfo32). Drill down to System Information --> System Summary to see the relevant information. It is usually best to select View --> Advanced. If in doubt, select Action --> Save As Text File..., and submit the resulting file for OpenLink review. Mac OS X, Linux, and other Unix-like OS users Execute the relevant command(s) listed below for your OS, and provide that output to your OpenLink contact(s).
