Hi I use Petsc 2.3.1 (I don't use the last version because I work on a software developed with this version). <br>I tried to used the Petsc socket, but the client and server programs but they don't connect (the execution is blocked).<br>
I am using two examples of Petsc: <a href="http://www.mcs.anl.gov/petsc/petsc-as/snapshots/petsc-current/src/vec/vec/examples/tutorials/ex42a.c.html" target="_blank">http://www.mcs.anl.gov/petsc/petsc-as/snapshots/petsc-current/src/vec/vec/examples/tutorials/ex42a.c.html</a> and<br>

<br>I tried to execute ex42a on machine and ex42 on other machine, and I execute both programs on same machine.</blockquote></div></div><div><br>1) It is extremely hard to debug old code. We have made several socket fixes for new OS/architectures.<br>
<br>2) Make sure you start the server (ex42a) and then the client (ex42)<br><br>3) Run using the debugger, -start_in_debugger, and give us a stack trace of the hang<br><br> Matt<br> </div><div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
<br>Do you help me? Thanks.<br>Bye.<br>
