+<p>With correct padding cache and TLB thrashing can be avoided. Therefore the
+number of (fluid) nodes used in the data layout is artificially increased.</p>
+<p>Currently automatic padding is active for kernels which support it. It can be
+controlled via the kernel parameter (i.e. parameter after the <tt class="docutils literal"><span class="pre">--</span></tt>)
+<tt class="docutils literal"><span class="pre">-pad</span></tt>. Supported values are <tt class="docutils literal">auto</tt> (default), <tt class="docutils literal">no</tt> (to disable padding),
+or a manual padding.</p>
+<p>Automatic padding tries to avoid cache and TLB thrashing and pads for a 32
+entry (huge pages) TLB with 8 sets and a 512 set (L2) cache. This reflects the
+parameters of current Intel based processors.</p>
+<p>Manual padding is done via a padding string and has the format
+<tt class="docutils literal"><span class="pre">mod_1+offset_1(,mod_n+offset_n)</span></tt>, which specifies numbers of bytes.
+SoA data layouts can exhibit TLB thrashing. Therefore we want to distribute the
+19 pages with one lattice (36 with two lattices) we are concurrently accessing
+over as much sets in the TLB as possible.
+This is controlled by the distance between the accessed pages, which is the
+number of (fluid) nodes in between them and can be adjusted by adding further
+(fluid) nodes.
+We want the distance d (in bytes) between two accessed pages to be e.g.
+<strong>d % (PAGE_SIZE * TLB_SETS) = PAGE_SIZE</strong>.
+This would distribute the pages evenly over the sets. Hereby <strong>PAGE_SIZE * TLB_SETS</strong>
+would be our <tt class="docutils literal">mod_1</tt> and <strong>PAGE_SIZE</strong> (after the =) our <tt class="docutils literal">offset_1</tt>.
+Measurements show that with only a quarter of half of a page size as offset
+higher performance is achieved, which is done by automatic padding.
+On top of this padding more paddings can be added. They are just added to the
+padding string and are separated by commas.</p>
+<p>A zero modulus in the padding string has a special meaning. Here the
+corresponding offset is just added to the number of nodes. A padding string
+like <tt class="docutils literal"><span class="pre">-pad</span> 0+16</tt> would at a static padding of two nodes (one node = 8 b).</p>
