Hi,<br><br>I switched my code from petsc 3.2 to petsc dev in order to use the newest superlu dist. And I also change MatCreateMPIAIJ to MatCreateAIJ as mentioned on developer site. However I got some errors which I did not have in petsc 3.2. From tracking the -info output, I found my code did not execute the MatAssembly correctly. The output file is attached. Thus I am wondering what else I should pay attention to when switching from 3.2 to dev. Thanks.<br>
<br>Regards,<br>Wen<br>
