Hello Matt...<br><br>1) configure.log attached<br><br>2) Yes, I am online. <br><br>3) At the moment I want to develop & run PARALLEL codes on my FC6 Desktop (single machine). Should I use the option --download-mpich=1 or --download-mpich=0

1) Always send configure.log<br><br>2) It appears that you cannot reach the PETSc ftp site. Are you online?<br><br> Matt<br><br>On 9/4/07, amjad ali <<a href="mailto:amjad11@gmail.com">amjad11@gmail.com</a>> wrote:
