KB441093: Mobile Processor Affinity Tool (MAMobileAff) is not working in MicroStrategy 10.x.

SYMPTOM
In Strategy 10.x, if user set Web and Mobile Servers to use different processors using Web Processor Affinity Tool and Mobile Processor Affinity tool, Mobile Server is always using the same processor as Web Server.
STEPS TO REPRODUCE

• Set Web Server to use Processor 2 using Web Processor Affinity tool (MAWebAff.exe) located in Install_Path:\Program Files (x86)\MicroStrategy\Web ASPx. Click 'Apply'.
  
  

•  Set Mobile Server to use Processor 3 using Mobile Processor Affinity tool (MAMobileAff.exe) located in Install_Path\Program Files (x86)\MicroStrategy\Mobile Server ASPx. Click 'Apply'. 
  
  

• Restart IIS.
• Generate request from both Strategy Web and Mobile client.
• Check Task Manager. For StrategyWebPool process, and CPU 4 and CPU 5 are allowed. For StrategyMobilePool process, same processors are allowed.   
  
  

• Open Resource Monitor. CPU 4 and CPU 5 are utilized.
  
  

• Do a swapping test by setting Web Server to use Processor 3 and Mobile Server to user Processor 4.
• Restart IIS.
• Generate request from both Strategy Web and Mobile client.
• Check Task Manager. For StrategyWebPool process, and CPU 6 and CPU 7 are allowed. For StrategyMobilePool process, same processors are allowed.  
  
  

• Open Resource Monitor. CPU 6 and CPU 7 are utilized.. 
  
  

• If user set Web to use CPU 4 and CPU 5 and Mobile to use CPU 6 and CPU 7 in task manager, after IIS is restarted, Web and Mobile Servers will inherit the setting in Web Processor Affinity tool.

CAUSE
WebAff and MAMobileAff tools are not been maintained in current releases. Strategy does not support these two tools anymore.
WORKAROUND
Set processor affinity directly in IIS.

• In IIS, go to Application Pools and find StrategyWebPool and StrategyMobilePool.

• Right-click on StrategyWebPool and go to Advanced Settings.
• Change "Processor Affinity Enabled" to true, and then set the value for "Processor Affinity Mask". 

•  Repeat steps 2-3 for the StrategyMobilePool. Make sure to set a different value for the "Processor Affinity Mask" so that it uses a different CPU.

Please note, Processor Affinity Mask is using binary code.
For example:
Mobile to use CPU5 -> 0010000 -> Processor Affinity Mask=32
Web to use CPU4   -> 0001000 -> Processor Affinity Mask=16
