<div dir="ltr">We have Titan working but we have a problem that we need lstdc++ to get PETSc to configure. Otherwise it fails to build fortran. This seems to only be needed for GNU. This is for PGI. If we remove this C++ works, otherwise there is a missing external. I guess I can just deploy two version, on for fortran and one for C++ (I have a C++ and a fortran code that I support).<br><br></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, May 12, 2015 at 9:36 AM, Barry Smith <span dir="ltr"><<a href="mailto:bsmith@mcs.anl.gov" target="_blank">bsmith@mcs.anl.gov</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div style="word-wrap:break-word"><div><br></div> Remind me again how much the US tax payers spend on this machine each year.<div><br><div><br><blockquote type="cite"><div>Begin forwarded message:</div><br><div style="margin-top:0px;margin-right:0px;margin-bottom:0px;margin-left:0px"><span style="font-family:-webkit-system-font,Helvetica Neue,Helvetica,sans-serif;color:rgba(0,0,0,1.0)"><b>From: </b></span><span style="font-family:-webkit-system-font,Helvetica Neue,Helvetica,sans-serif">Mark Adams <<a href="mailto:mfadams@lbl.gov" target="_blank">mfadams@lbl.gov</a>><br></span></div><span class=""><div style="margin-top:0px;margin-right:0px;margin-bottom:0px;margin-left:0px"><span style="font-family:-webkit-system-font,Helvetica Neue,Helvetica,sans-serif;color:rgba(0,0,0,1.0)"><b>Subject: </b></span><span style="font-family:-webkit-system-font,Helvetica Neue,Helvetica,sans-serif"><b>Re: [petsc-users] configure error on Titan with Intel</b><br></span></div></span><div style="margin-top:0px;margin-right:0px;margin-bottom:0px;margin-left:0px"><span style="font-family:-webkit-system-font,Helvetica Neue,Helvetica,sans-serif;color:rgba(0,0,0,1.0)"><b>Date: </b></span><span style="font-family:-webkit-system-font,Helvetica Neue,Helvetica,sans-serif">May 12, 2015 at 11:12:55 AM CDT<br></span></div><div style="margin-top:0px;margin-right:0px;margin-bottom:0px;margin-left:0px"><span style="font-family:-webkit-system-font,Helvetica Neue,Helvetica,sans-serif;color:rgba(0,0,0,1.0)"><b>To: </b></span><span style="font-family:-webkit-system-font,Helvetica Neue,Helvetica,sans-serif">Barry Smith <<a href="mailto:bsmith@mcs.anl.gov" target="_blank">bsmith@mcs.anl.gov</a>><br></span></div><div style="margin-top:0px;margin-right:0px;margin-bottom:0px;margin-left:0px"><span style="font-family:-webkit-system-font,Helvetica Neue,Helvetica,sans-serif;color:rgba(0,0,0,1.0)"><b>Cc: </b></span><span style="font-family:-webkit-system-font,Helvetica Neue,Helvetica,sans-serif">Jed Brown <<a href="mailto:jed@jedbrown.org" target="_blank">jed@jedbrown.org</a>>, petsc-users <<a href="mailto:petsc-users@mcs.anl.gov" target="_blank">petsc-users@mcs.anl.gov</a>>, "David Trebotich" <<a href="mailto:treb@lbl.gov" target="_blank">treb@lbl.gov</a>>, "D'Azevedo, Ed F." <<a href="mailto:dazevedoef@ornl.gov" target="_blank">dazevedoef@ornl.gov</a>><br></span></div><div><div class="h5"><br><div><div dir="ltr"><br><div class="gmail_extra"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><span>
