<p>Creates a new node which performs no operation, and adds it to <tt class="ph tt code">hGraph</tt> with <tt class="ph tt code">numDependencies</tt> dependencies specified via <tt class="ph tt code">dependencies</tt>.

<p class="p">An empty node performs no operation during execution, but can be used for transitive ordering. For example, a phased execution
graph with 2 groups of n nodes with a barrier between them can be represented using an empty node and 2*n dependency edges,
rather than no empty node and n^2 dependency edges.

<p class="p">When the graph is launched, the node will invoke kernel <tt class="ph tt code">func</tt> on a (<tt class="ph tt code">gridDimX</tt> x <tt class="ph tt code">gridDimY</tt> x <tt class="ph tt code">gridDimZ</tt>) grid of blocks. Each block contains (<tt class="ph tt code">blockDimX</tt> x <tt class="ph tt code">blockDimY</tt> x <tt class="ph tt code">blockDimZ</tt>) threads.
</p>
<p class="p"><tt class="ph tt code">sharedMemBytes</tt> sets the amount of dynamic shared memory that will be available to each thread block.
</p>
<p class="p">Kernel parameters to <tt class="ph tt code">func</tt> can be specified in one of two ways:
</p>
<p class="p">1) Kernel parameters can be specified via <tt class="ph tt code">kernelParams</tt>. If the kernel has N parameters, then <tt class="ph tt code">kernelParams</tt> needs to be an array of N pointers. Each pointer, from <tt class="ph tt code">kernelParams</tt>[0] to <tt class="ph tt code">kernelParams</tt>[N-1], points to the region of memory from which the actual parameter will be copied. The number of kernel parameters and
their offsets and sizes do not need to be specified as that information is retrieved directly from the kernel's image.
</p>
<p class="p">2) Kernel parameters can also be packaged by the application into a single buffer that is passed in via <tt class="ph tt code">extra</tt>. This places the burden on the application of knowing each kernel parameter's size and alignment/padding within the buffer.
The <tt class="ph tt code">extra</tt> parameter exists to allow this function to take additional less commonly used arguments. <tt class="ph tt code">extra</tt> specifies a list of names of extra settings and their corresponding values. Each extra setting name is immediately followed
by the corresponding value. The list must be terminated with either NULL or CU_LAUNCH_PARAM_END.
