[Dune] Read in matrix and rhs, solve linear system

Thu Aug 27 16:29:29 CEST 2015

That worked. Thank you!

Regarding compilation:

Do I have to set optimization flags for benchmark runs? Or does it automatically build optimized versions?

Regarding dune-mm-amg-master:

How can I run the amg method in parallel? (Reason: >6mio unknowns)

I assume in line 66: 1e-6 is the relative decrease in residual and 80 is the maximum number of iterations.
Can I also prescribe an absolute value for the residual?

Thank you again for your help!

Henrik

/home/user/Code/Dune/dune-mm-amg-master/src/matrixmarket-amg.cc: In function 'int main()':

/home/user/Code/Dune/dune-mm-amg-master/src/matrixmarket-amg.cc:35: error: using 'typename' outside of template

That's a bug in matrixmarket-amg.cc.  Simply remove the word 'typename' from line 35.

Best,
Oliver

Terminating dunecontrol due to previous errors!

Hi,

to be honest, I have no idea.  But for the AMG you don't actually need Boost,

so if everything else fails you can try to comment-out the Boost-related lines

in dune-istl/cmake/modules/DuneIstlMacros.cmake.

Best,

Oliver

Dear Oliver! Dear Markus!

I downloaded dune-common, dune-istl and dune-mm-amg. Now I try to build the packages with

./dune-common-2.4/bin/dunecontrol --module=dune-mm-amg all --opts=/home/user/Code/Dune/dune.options

My options file looks like:

# use a custom directory, default is /usr/local/bin

CONFIGURE_FLAGS="--prefix='/home/user/Code/Dune'"

# Set the default target of make to install. Now the call above will

# not just build the DUNE modules but also install it

MAKE_FLAGS=install

# The default versions of automake and autogen are not sufficient

# therefore we need to specify what versions to use

AUTOGEN_FLAGS="--ac=2.59 --am=1.9"

I'm getting errors complaining about the Boost library. I attached the log. The first error you can find below.

Any ideas what I'm doing wrong here? I have not super user rights on my account.

@Markus: After compiling can I then run AMG also in parallel? My matrix is quite big (>6 mio unknowns) and thus I benchmark in parallel.
