<div>I am already using superlu_dist 6.1 but I used to "--download-superlu_dist=1 --download-superlu_dist-commit=001d994a22684fd60cab5530cc2192f19fc58e83" when configuring petsc, is this ok?</div>
<div name="quote" style="margin:10px 5px 5px 10px; padding: 10px 0 10px 10px; border-left:2px solid #C3D9E5; word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;">
<div style="margin:0 0 10px 0;"> </div>
<div name="quoted-content">Don't remember - but you can try with latest superlu_dist and see if<br/>
the problem persists. [it has a bunch of fixes]<br/>
<br/>
To try latest superlu_dist - you can use balay/update-superlu_dist_6.1.0/maint_no_merge<br/>
<br/>
[this branch is off maint - so to try with master - you can merge this with master]<br/>
<br/>
git checkout master<br/>
git checkout -b test<br/>
git merge origin/balay/update-superlu_dist_6.1.0/maint_no_merge<br/>
