<h4 class="subsection">6.31.22 Nvidia PTX Function Attributes</h4>
|
|
|
|
<p>These function attributes are supported by the Nvidia PTX back end:
|
|
</p>
|
|
<dl compact="compact">
|
|
<dt><code>kernel</code></dt>
|
|
<dd><a name="index-kernel-attribute_002c-Nvidia-PTX"></a>
|
|
<p>This attribute indicates that the corresponding function should be compiled
|
|
as a kernel function, which can be invoked from the host via the CUDA RT
|
|
library.
|
|
By default functions are only callable only from other PTX functions.
|
|
</p>
|
|
<p>Kernel functions must have <code>void</code> return type.
|
|
