D. Current Software Notes
	
   LoopTool:


    NOTE    Inner/Outer Loop Times:  Loop times are measured as wallclock
            elapsed time.  If a loop is parallelized, it is credited with
            the elapsed time for all of the instances of the loop.  Thus,
            inner parallelized loops may sometimes be credited with more
            elapsed runtime than the outer loop that encompasses the
            parallelized loop.  This is not a bug - this is expected
            behavior! - but it can be misleading.  

    NOTE    Cutoff:  The looptool GUI allows you to specify a "cutoff."
            This cutoff figure should be entered as an integer between
            0 and 100.  The loops shown in the histogram are those that
            account for cutoff% of the runtime of the longest running loop.
            This is not a bug, but since the looptool GUI does not explain
            this, the cutoff figure may be mysterious at first. 

     NOTE   Source directory:  If looptool cannot find the source file
            for a selected loop, it prompts you for the source path.
            Simply choose any file in the source directory that contains
            the source file(s) for your program - it is not necessary
            to select the exact file name.
