<p>I have set up the Einstein Toolkit on an Ubuntu 18 computer. The compiliation went ok and has completed. When I run the helloworld example it fails</p>

<p>This is after a clean compilation based on the documentation found found here:</p>

<p>from what I can dig up from google it seems like some kind of mpi mismatch, but isn’t this supposed to compile it’s own MPI?<br />
Can I force it to do that?</p>
<p>I don’t know how to fix this. If anyone has any ideas that would be great. I can delete everything and start over if needed</p>
<p>Thank you</p>
