Dear all,<br>
<br>
it's all working now. What I wrote earlier today was only partially
correct, once I use the correct git command "git checkout
releases/2.2" (i.e. without the -b) I change the working copy the
release 2.2 branch and that does indeed not contain the patch, so I
applied it manually.<br>
<br>
Once I've done this I can compile DUNE (with UGGrid and ALUGrid) and
also the multigrid code.<br>
<br>
Thanks a lot again for your help!<br>
<br>

Hi Oliver,<br>
<br>
thanks a lot, I just cloned the dune-common repository and
switched to the releases/2.2 branch with "git checkout -b
releases/2.2". I guess this is newer than the 2.2.1 tarball and
contains further bugfixes? It already seems to contain the MPICH 3
fix already and compiles ok on ARCHER.<br>
<br>
ARCHER (

has actually less cores than HECToR (~70,000) but they are Intel
Ivybridge (instead of AMD Opterons) and roughly 2x faster
(according to other's peoples experiences). On HECToR the DUNE
multigrid is about a factor 2x slower than my handwritten Fortran
code, so I want to check whether this difference disappears when I
go to ARCHER. I also tried to play around with the compiler flags
on HECToR, but there I never gain more than 5% (addmitedly I only
changed the flags for my own DUNE multigrid module, and didn't
recompile UG or DUNE-grid, but the code only has a 10%-20%
overhead from iterating over the grid, so that should not make a
big difference).<br>
<br>
I'm hoping to still do a 80,000 core run on HECToR anyway before
it is decommisioned in March.<br>
<br>
Cheers,<br>
<br>

<pre wrap="">Hi Steffen and Markus,
thanks a lot, I looked at the mpi.h on my system and it indeed looks like it's MPICH 3.0 (there's a #define MPICH_VERSION "3.0.3"). Yes, I'm using version 2.2.1 of DUNE.
As for UG, I was also using a slightly older version (patched with patch10-rc4), so I have now updated this with the latest patch as well, which fixes the problem there, I can configure, compile and install UG Grid with this.
I also downloaded the 2.2.1 tarball of DUNE again and successfully applied the patch you describe for m4/mpi-config.m4. Unfortunately that does not seem to help, and I suspect this is because the tarball contains aclocal.m4, which does not contain the test_mpich3() marco. I don't know much about autotools, but when I try to delete aclocal.m4 and regenerate it with aclocal I run into a different problem:
eike@eslogin004 $ aclocal
configure.ac:6: error: m4_defn: undefined macro: _m4_divert_diversion
configure.ac:6: the top level
autom4te: /usr/bin/m4 failed with exit status: 1
aclocal: autom4te failed with exit status: 1

<pre wrap="">Hi Eike,
quick solution:
clone into dune-common, change to the 2.2 branch, apply the patch there and do a 'make dist'.
That gives you a tarball with the patch.
ideal solution: we do that for you, and do a 2.2.2 release of dune-common.
PS: That Archer thing has how many processors? What's your goal with UG?
Cheers,
Oliver [waiting for new bugreports :-) ]

<pre wrap="">Apart from this, just looking through the patch, running ./conftest in mpi_trybuild_run() might not work as the MPI compiler is configued to cross-compile for the compute nodes, so I'm not sure I can execute anything on the login nodes, but I will find out once the configure runs.
Thanks,
Eike

<pre wrap="">Hi Eike,
what is the version of MPICH as reported by the command mpichversion or the module
system? There was a problem with MPICH 3.x which has been fixed in the master branch
of Dune (and I think also in the development version of UG), but I don’t know whether those
fixes have made it to the releases yet…

<pre wrap="">That one is in the release.

<pre wrap="">Ah, that’s good! :-)
But if Eike is still on 2.2.1, he doesn’t have that patch yet...
