<p>Programs written using ArrayFire are portable across CUDA, OpenCL and CPU devices.</p>
<p>The default backend is chosen in the following order of preference based on the available libraries:</p>
<blockquote>
<div><ol class="arabic simple">
<li>CUDA</li>
<li>OpenCL</li>
<li>CPU</li>
</ol>
</div></blockquote>
<p>The backend can be chosen at the beginning of the program by using the following function</p>
<div class="highlight-default"><div class="highlight"><pre><span></span><span class="gp">&gt;&gt;&gt; </span><span class="n">af</span><span class="o">.</span><span class="n">backend</span><span class="o">.</span><span class="n">set</span><span class="p">(</span><span class="n">name</span><span class="p">)</span>
</pre></div>
</div>
<p>where name is one of &#8216;cuda&#8217;, &#8216;opencl&#8217; or &#8216;cpu&#8217;.</p>
<p>The functionality provided by ArrayFire spans the following domains:</p>
<blockquote>
<div><ol class="arabic simple">
<li>Vector Algorithms</li>
<li>Image Processing</li>
<li>Signal Processing</li>
<li>Computer Vision</li>
