	<title>Exercise 5: Cache Optimization</title>
</head>
<body>
	<center><h1>Optimizing Algorithms for the L1 Cache</h1>
		<h3>Autograder README</h3></center>

	<p><font size="-1"><b>NOTE:</b> You will need Perl installed to use the automatic grading script. Perl is freely available <a href="http://www.activestate.com/Products/Download/Register.plex?id=ActivePerl">here</a>.</font></p>

	<p>The grading script 'Autograder.pl' included in the same archive as this writeup provides an automatic means of compiling and executing the student handins.  </p>
	
	<p>Use the CTEGrader tool as usual to download the student handins.  Upon executing the Autograder.pl, it will ask you for the directory in which you store your CTEGrader downloads.  (This will be the same directory specified in the CTEGrader Options dialog).  After that the script will go through the student handin directories and automatically compile and execute each handin, leaving in each directory a results.txt file that contains the output of the program's execution.  This results file should contain all of the numbers relevant to a quantitative grade.</p>

	<p>Do look through the students' solutions to ensure that no one is making unnecessary repeated calls to the cache in an attempt to increase the hit rate.</p>
	
	<p>Also included in this archive are two reference solutions, <kbd>rotate-sol.c</kbd> and <kbd>smooth-sol.c</kbd>.  You can run test the effectiveness of these solutions by copying the files over <kbd>rotate.c</kbd> and <kbd>smooth.c</kbd> respectively in orig_codefiles, and then opening the project file there and choosing Build, Execute.
