Performance of certain application classes (in particular memory bound computation kernels) may depend on the addresses of physical frames used to back the application memory structures. Automated performance evaluation experiments may yield very regular frame allocation behavior, which can lead to biased measurement results. The Frame Allocation Randomizer attempts to disrupt the frame allocation behavior to prevent such bias.
Simply execute the frame-randomizer binary with root privileges (needed to drop page cache content).
The Frame Allocation Randomizer works by allocating all available physical memory in one chunk and then releasing individual frames in random order. This temporarily puts the system in low memory situation. To prevent errors, other system activities should be suspended.
