<p class="p1">You can increase the maximum number of atoms by passing the +t option to the emulator:</p>

<p class="p1">http://www.erlang.org/doc/efficiency_guide/advanced.html#atoms</p>
<p class="p2"><br></p>
<p class="p1">Not sure how to pass emulator options to erlc but you can use something like:</p>
<p class="p2"><br></p>
<p class="p1">erl +t <numberofatoms> -compile Mod1 Mod2</p>
<p class="p2"><br></p>
<p class="p1">or also use -make if you want to.</p>

<p class="p3">I don't necessarily need to do what I am doing, it just works quite well ... up to a point. The alternative involves a lot of list processing. Clause head matching on the other hand is really fast. My challenge is to match a very large number of patterns and to do it very fast and with the lowest cost.</p>
