<p class="MsoNormal">If `configure` detects CUDA runtime, GPU support is always enabled. You can pass in `--with-cuda=path/to/cuda` for custom CUDA locations. Unfortunately, there isn’t an obvious way to disable GPU support if CUDA library is in the system
path.<o:p></o:p></p>

<p class="MsoNormal" style="margin-left:.5in"> <o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in">I just downloaded mpich-3.4.1 and I want to try and configure and build it with GPU support. There doesn’t appear to be any documentation on how to go about this, or at least it is very well hidden. Can you tell
me where to find information?<o:p></o:p></p>
