int arrA[]={1,2,3,..........100};
I want to get arrB={100,.......3,2,1};
What's the fastest fun?

If I want to get arrA={100,.......3,2,1},too;
MKL doesn't have such functions, but you may have a look at the existing IPP functionality ( ippsFlip_*,* or ippsSortAscend/Descend ).
https://software.intel.com/en-us/node/502149.
C++ reverse_copy() is optimized for the designated architecture by Intel C++ and g++. A plain loop would work as well.
By the way, note that "Rotate" is not an apt word for what you want to do. "Reverse", "Reflect" or the more flippant "Flip" would be more appropriate.
