<br>Please respect the following rules:<br><br>- Remain polite, courteous, respectful and constructive throughout<br> the correction process. The well-being of the community depends on<br> it.<br><br>- Identify with the person (or the group) graded the eventual<br> dysfunctions of the work. Take the time to discuss and debate the<br> problems you have identified.<br><br>- You must consider that there might be some difference in how your<br> peers might have understood the project's instructions and the<br> scope of its functionalities. Always keep an open mind and grade<br> him/her as honestly as possible. The pedagogy is valid only and<br> only if peer-evaluation is conducted seriously.<br>

<h4 class="scale-question-name">Malloc test</h4>
<p class="scale-section-guidelines">
</p><p>We are first going to make a first test program that does not<br>
use malloc, so that we have a base to compare to.</p>
<p>Use test0.c file attached in the scale<br>
WARNING: If you are using a linux vm, make sure that you are using the <br>
time binary that you can get with apt (sudo apt install time), else<br>
you won't have access to the -v option.</p>
<p>MAC:</p>
<pre><code> $&gt; gcc -o test0 test0.c &amp;&amp; /usr/bin/time -l ./test0
</code></pre>
<p>LINUX:</p>
<pre><code> $&gt; gcc -o test0 test0.c &amp;&amp; /usr/bin/time -v ./test0
</code></pre>
<p>We will then add a malloc and write in each allocation to make<br>
sure that the memory page is allocated in physical memory by<br>
MMU. The system will only really allocate the memory of a page<br>
if you write in it, so even if we do a bigger mmap than the<br>
malloc request it won't modify the "page reclaims".</p>
<p>For Linux =&gt; Major, Minor </p>
<p>For Mac OS X =&gt; page reclaims, page faults</p>
<p>Using the test1.c file given as attachment, run the following tests<br>
MAC:</p>
<pre><code> $&gt; gcc -o test1 test1.c &amp;&amp; /usr/bin/time -l ./test1
</code></pre>
<p>LINUX:</p>
<pre><code> $&gt; gcc -o test1 test1.c &amp;&amp; /usr/bin/time -v ./test1
</code></pre>
<p>Our test1 program requested 1024 times 1024 bytes, so 1Mbyte. We<br>
can therefore check by doing the difference with the test0<br>
program:</p>
<ul>
<li>either between the "maximum resident set size" lines, we
obtain a little more than 1Mbyte</li>
<li>or between the page reclaims lines that we will multiply by
the value of getpagesize(3) under OSX or sysconf(_SC_PAGESIZE) under linux.</li>
</ul>
<h2 id="let-39-s-test-now-both-programs-with-our-library">Let's test now both programs with our library:</h2>

<pre><code>$&gt;chmod 777 run_mac.sh

202 page reclaims

<p>Count the number of pages used in addition to the real malloc and adjust the score accordingly:</p>
<ul>

<li>between 91 pages and 180 pages, malloc works but the
