 ### What if the host has only one core?
 
 In this case, the parameters \b OneCore and \b AllCores are obviously the same.
-Actually, SimGrid expect an energetic profile formated as 'Idle:Running' for mono-cores hosts.
+Actually, SimGrid expect an energetic profile formatted as 'Idle:Running' for mono-cores hosts.
 If you insist on passing 3 parameters in this case, then you must have the same value for \b OneCore and \b AllCores.
