Subcapacity licensing is available in SAS 9.2 for Microsoft Windows operating systems. This allows SAS licensing based on the number of CPUs that are on a machine. Further details about subcapacity licensing for Windows operating systems are documented in SAS Note 41121: "Starting in SAS^® 9.2, a SAS^® subcapacity license for a Microsoft Windows operating system is available and includes number of cores and computer name."

If the number of CPUs is limited in the BIOS, and hyper-threading is turned on, then the number of CPUs that is reported to SAS is increased by the number of threads. On a SAS installation with subcapacity licensing, the false number of CPUs that is reported produces the following SAS error message:

ERROR: The SAS System is executing on a processor (CPU) whose model name, model
       number, and serial number are not included in the setinit data used to
       initialize the SAS System library in use. This is permitted if this
       processor is a designated backup processor for a licensed CPU. For this
       site, the SAS system is licensed for the following CPU serial numbers:

            Model **your-machine-name* Serial Number +1

ERROR: You are licensed to run on a system with a CPU of no more than 1 but the
       actual CPU count is 2.

The numbers that are included in the preceding error message vary depending on the number of CPUs that are on the machine and the number of CPUs that are licensed.

To work around this problem, turn off hyper-threading.
