Let me port first and then I'll follow your instructions for the tests.<br>

I've put together an experimental simfactory entry to the new nodes. It runs, and tests pass (except the ones from Dissipation). It should be considered experimental because it does not fully implement proper logging in, and I also used a compute node to compile (because I didn't want to mess with cross-compiling on my first try). This works, but makes using the machine a bit more 'hand-work' than others.<br>
<br>
I'll upload those soon to simfactory, marked as 'experimental'.<span class="m_-4030551970598862956HOEnZb"><font color="#888888"><br>
