Bugzilla Bug 53394

Please find attached a new ebuild for Metis-4.0.

From the website (http://www-users.cs.umn.edu/~karypis/metis/metis/index.html) you can read the following description:

" METIS is a set of programs for partitioning graphs, partitioning finite element meshes, and for producing fill reducing orderings for sparse matrices. The algorithms implemented in METIS are based on the multilevel graph partitioning schemes."

It's a highly utilized tool for parallel computing, either on shared or distributed memory machines.

My suggestion is to place it in app-sci/metis.

metis-4.0.ebuild

Initial ebuild for Metis-4.0

Nice,
 you took care of modifying the names of the installed objects 
so that this package can coexist with parmetis. I saw you
mentioned in bug 49953 you wanted to try the ebuild for metis,
so I guess you have parmetis installed as well.

I do not think we need a metis-config, so I guess this is the best way.

Indeed the parmetis ebuild I provided lacks executables, it is 
just the core libraries.

I see we are from the same place, must meet sooner or later :)

the same ebuild with updated url

this is just the same ebuild but with a new download url. I guess they changed
it...

metis-5.0_pre2 ebuild

Version bump for metis.  This is required for cholmod to build as referred to
in bug #173900.

Also added a patch to use autotools.

metis-5.0_pre2-autotools.patch

Hi

I put metis-5.0_pre2 in the science overlay. Please test it and review changes
I made (quite a lot) with respect to the one posted here, and the autotools
patch.

I could push it to the main tree, however I don't know the package.
The default src_test is quite buggy right now. So I would need someone
interested to work out a src_test (or equivalently an autotools test suite).
Also would we need metis-4.0.2 as well?

Looks good to me.  I pushed the changes your changes to our local overlay.

As far as testing goes, I am only the middle man supplying the ebuilds to
others.  I had to grab metis-5.0_pre* because cholmod requires metis.h, which
appears to have been introduced in the newer versions.  So, in my case at
least, I don't have any need for 4.0.2.

Thanks,

Indeed. Metis 4.0 is still quite used in many projects (some of then legacy
code), so I find it usefull to keep around. Maybe with a slotted installation?

Anyway, thanks for putting metis in the science overlay.
I use this overlay on all my machines, so its quite usefull.

Best, Tiago Quintino

Now in the main tree. I masked metis-5* for now, since it is quite
experimental. metis-4.0.1 is not masked.
