<div dir="ltr">Sorry, to expand my answer, "what Matt said". You don't have the advantage of using the functionality of -start_in_debugger if you cannot make X11 connections from the compute nodes, so you will need to rely on whatever debugging facilities your systems team has set up, and break on PetscError if you want to catch PETSc errors percolating up the stack.<div>

Hi,<br>
I am debugging my code on a system that does not allow any X11<br>
connections, therefore the following does not work:<br>
<br>
mpiexec -n 2 solver run.xml -start_in_debugger -display :0.0<br>
<br>
Are there alternative ways of using a debugger circumventing X11 connections?<br></blockquote><div><br></div></div></div><div>No. You can usually set the DISPLAY correctly for the backend machine. Consult the admin.</div>
