It tries to find the executable in PATH, maybe you need mpiexec -n ./app instead of mpiexec -n app.<div class="gmail_extra"><br><br><div class="gmail_quote">On Mon, Nov 26, 2012 at 1:35 AM, Zhenglun (Alan) Wei <span dir="ltr"><<a href="mailto:zhenglun.wei@gmail.com" target="_blank">zhenglun.wei@gmail.com</a>></span> wrote:<br>

<div>Thank you so much, Dr. Brown. <br>
Another little question is that: <br>
After I update the PETSc, the
${PETSC_ARCH}/conf/bin/mpiexec does not work and shows:<br>
[<a href="mailto:mpiexec@...edu" target="_blank">mpiexec@...edu</a>] set_default_values (./ui/mpich/utils.c:1541): no
executable provided<br>
[<a href="mailto:mpiexec@...edu" target="_blank">mpiexec@...edu</a>] HYD_uii_mpx_get_parameters
(./ui/mpich/utils.c:1745): setting default values failed<br>
[<a href="mailto:mpiexec@...edu" target="_blank">mpiexec@...edu</a>] main (./ui/mpich/mpiexec.c:154): error parsing
parameters<br>
Any idea on this?<br>
<br>
thanks,<br>

mergetool or something. You can use hg revert to discard any local

use hg clean (this will delete all untracked files!) to get back
to a state like if you had a fresh clone.

Thank you so much for your help. Here I
have another question.<br>
After updating the PETSc, I tried to 'make
ex45' in /src/ksp/ksp/example/tutorial/. It says
that 'petscksp.h' can not be found; therefore, I
commented this library in ex45.c to see what
will happen. It, then, shows that the
'petscdmmg.h' can not be found. Any idea on
this? :)<br>

</div>
<div>Since DMMG is gone, baby gone, this means
your environment (PETSC_DIR) is still pointing
to an old version of PETSc.</div>
</div>
</div>
</blockquote>
</div>
Since my PETSc was updated, the PETSC_DIR of the new
version of the PETSc should be the same as the old version
of the PETSc, isn't it? <br>
BTW, it works after I re-configure and make the
PETSc. However, I found that it as a lot of dummy things
in the ex45.c, i.e.:<br>
<<<<<<<<<<local<br>
<br>
========<br>
<br>
>>>>>>>>>other<br>
<br>
=========<br>
<br>
It seems that the update changes the original program
of ex45.c by adding fractions of the new code into the old
code. It confused me a lot. Is there any way that I can
just replace the old code by the new code?<br>
<br>
thanks,<br>

Great! Glad to know it's working.<br>

Although, it always giev me the warning

it updated lots of files. Should I just
ignore this warning?<br>

You could ignore those warnings, yes, but
it would probably be better<br>
to upgrade your mercurial and see if the
host fingerprint option<br>
works. Or you could try to use the ssh
protocol, assuming your<br>
university proxy allows ssh out.<br>

the reason I used 'https' instead of
'http' is that 'https' is shown<br>
in the website you gave to me. :) It may
needs to be changed.<br>

Well, as I said previously, bitbucket
redirects all http traffic to<br>
https, so I don't think changing it to
just http would really work.<br>
