MAD tool question

HI ,

    I want to use TI MAD tools for C6678. After reading the MAD user guild ,I have some question

  The following comes from deployment_template_C6678_windows.json .I cannot understand the function of allowedCores.

  In my point of  view, appDeployment  has told the MAD TOOL which application will run the specific core.

So why do we need to define the allowedCores?

  {
   "name"    : "app2",
   "fileName"       : "..\\mad-loader\\examples\\app_2\\build\\app_2.exe",
   "libPath"        : "..\\mad-loader\\examples\\shlibs\\build",
   "allowedCores"   : [0,1,2,3,4,5,6,7]
  }
 ],
 
 "appDeployment" : [
  "app1",
  "app2",
  "app1",
  "app2",
  "app1",
  "app2",
  "app1",
  "app2"
 ]
}
