<div dir="ltr">Hi,<div><br></div><div>I'm getting segmentation fault while assembling large matrices (~4000000 X 4000000) across 480 processors. The error usually shows up randomly only in large problems (i.e, when I exceed matrix size of ~2000000x200000). There are few rows in my matrix for which non-local contributions are added from all other processors. So I believe the buffer size during MatSetValues gets larger with matrix size which in some way signals a segmentation fault. So is there a smart way of avoiding such error?</div><div><br></div><div>Regards,</div><div>Bikash <br clear="all"><div><br></div>-- <br><div class="gmail_signature"><div dir="ltr"><div><div><div><div><font color="#666666">Bikash S.
