+title: "Memory Hierarchies"
+---
+
+Review the memory mountain hands-on and look into the source code:
+In `main()` the function `run()` is called for each combination of `size` and `stride`
+which in turn calls `fcyc2()` and `fcyc2_full()`.
+
+What happens there to ensure that only the desired cache effects for the test function `f` are measured?
+Describe the mechanism and why it is necessary for accurate measurements in a short paragraph.
+Refer to the code and what you learned in the lecture about it.
