+        <readme>ATLAS_LIB_DIR and ATLAS_INCLUDE_DIR will be set (including libatlas.a).
+        During ATLAS library compilation, ATLAS performs code efficiency checks. These checks can only provide optimal results, if "frequency scaling" is disabled on the CPU, and no other load-intense processes are running. 
+        Ideally, you should compile on an empty cluster node with CPU frequency scaling disabled (see "cpufreq-selector" or "cpufreq-set").
