<div dir="ltr">Hello PETSc's frieds,<div><br></div><div>It is a couple of weeks that I am trying to enhance the perforamance of my code. Actually I am solving NS equation for a 3D problem of 220k cells with 4procs on my laptop (i7-7800k @ 2.3Ghz with dynamic overclocking). I have installed petsc under linux suse 15 in a virtual machine (I do not know if this is important or not). </div><div><br></div><div>After some profiling, I can see that the bottle neck is inside KSPSolve while solving pressure equation (solved with cg + hypre pc). For this reason my code is running twice time slower than openFOAM and the gap is only due the solution of pressure. Have you got some hints for me? At this point I am sure I am doing something wrong! I have attached the log of a test simulation.</div><div><br></div><div>Thank you very much!</div><div><br></div><div><div><div class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr">------<div><br></div><div>Edoardo Alinovi, Ph.D.</div><div><br></div><div>DICCA, Scuola Politecnica<br>Universita' di Genova<br>1, via Montallegro<br>16145 Genova, Italy<br></div><div><br></div><div>email: <a href="mailto:edoardo.alinovi@dicca.unige.it" target="_blank">edoardo.alinovi@dicca.unige.it</a></div><div>Tel: +39 010 353 2540<br></div><div><br></div><div><br></div></div></div></div>
