Construct an instance of class GpuDoubleVbl by calling the <a href="../../../edu/rit/gpu/Module.html#getDoubleVbl(java.lang.String)"><code>getDoubleVbl()</code></a> method on a <a href="../../../edu/rit/gpu/Module.html" title="class in edu.rit.gpu">Module</a> object.

Set the <a href="../../../edu/rit/gpu/GpuDoubleVbl.html#item"><code>item</code></a> field to the desired value. Call the <a href="../../../edu/rit/gpu/GpuDoubleVbl.html#hostToDev()"><code>hostToDev()</code></a> method to copy the variable from CPU memory to GPU

Call the <a href="../../../edu/rit/gpu/GpuDoubleVbl.html#devToHost()"><code>devToHost()</code></a> method to copy the variable from
