Hello,<br>
<br>
Lately I experienced very weird behavior in PETSC.<br>
<br>
While solving small size problem (25k) on my laptop, it MatDestroy clean the objects.<br>
Another test (40k unknowns) problem use most of my memory and left around 500 MB free while solving the problem.<br>
<br>
Then when I call MatDestroy, PETSC request more memory and the available memory goes down 8MB (It start scratching my hdd, so I stopped).<br>
<br>
Why MatDestroy need more memory than solving phase ?<br></blockquote><div><br></div><div>This is a misinterpretation. MatDestroy() does not allocate memory.</div><div><br></div><div> Thanks,</div><div><br></div><div> Matt</div>
