Hi guys,<div> I hope you're having a nice day.<br> I was trying to run ex29.c in src/ksp/ksp/example/tutorial. It is normal to go through without MPI. However, with the same grid size, if I run it with 4 processes with MPI, a error message of "Caught signal number 11 SEGV: Segmentation Violation, probably memory access out of range" will show up. Did anyone have this kind of issue before. I guess this is probably caused by the way I launched the 'mpiexec'. Any idea on it? The full error message is attached.</div>
<div> Thanks in advance. </div><div><br></div><div>best,</div><div>Alan</div>
