<div dir="ltr"><div>Hi,<br><br>I see a 4x increase in the memory usage when I change from DMDA_STENCIL_STAR to DMDA_STENCIL_BOX. Attached are the outputs of -log_summary which shows a huge increase in the matrix memory usage. Is this expected?<br>
<br></div>On a different note, suppose I am running a serial calculation with no need to exchange data but I am using corner node information, do I need to use DMDA_STENCIL_BOX? Would the jacobian when computed using colored finite differences be correctly represented if I use corner information but still use DMDA_STENCIL_STAR?<br>
<br>Thanks,<br>Mani<br><div><div><br><div><br></div></div></div></div>
