When you use a Tabular instance of Microsoft SQL Server 2016 Analysis Services on a computer that has multiple processor groups, you may experience one or more of the following issues:
- The group affinity settings for the Analysis Services (Tabular mode) threads are not logged in Msmdsrv.log.
- Analysis Services (Tabular mode) can use only the processors in the first processor group regardless of the configuration in the Msmdsrv.ini file.
- The limit on the number of cores that can be used by a specific edition of Analysis Services (Tabular mode) is not correctly implemented.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
