<div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">I use Fedora 15 and I needed to make a new install of the system. However, when I installed petsc mpiexec did not work. Fedora 15 uses now mpich2-1.4.1 which uses hydra as the default process manager. But nothing is working. Any suggestions about what should I check and what to do?</blockquote>
<div><br></div><div>I use mpich2-1.4.1 on all my systems (mac and linux) and have no problem with hydra. What went wrong? A configure error? A make error? Or a runtime error? I think regardless of which error it is, you should send your configure.log (and make.log if it got that far) to petsc-maint.</div>
