<br>
I am currently working on the development of a in-house molecular dynamics code using PETSc and C++. So far the code works great, however it is a little bit slow since I am not exploiting MPI for PETSc vectors. I was wondering if there is a way to perform the domain decomposition efficiently using some PETSc functionality. Any feedback is highly appreciated.<br></blockquote></div></blockquote><div><br></div><div>It sounds like you mean "is there a way to specify a communication construct that can send my particle</div><div>information automatically". We use PetscSF for that. You can see how this works with the DMSwarm class, which represents a particle discretization. You can either use that, or if it does not work for you, do the same things with your class.</div><div><br></div><div> Thanks,</div><div><br></div><div> Matt</div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
