octave forge

Hi,

Bug #179885 [1] is the tracker for the octave forge split ebuilds. I 
attached to it some ebuilds, nearly all of the remaining packages, but 
nobody seems to care, despite being a blocker for gcc-4.3 stabilization 
and with an ancient octave-forge in portage that doesn't work with the 
non-ancient octave-3*.

Pinging markusle aside, there are a lot of forge packages that shouldn't 
monopolize the sci-mathematics category, so something must be made. 
Possible solutions:

1.- Do nothing, thats not a problem.
2.- Create a new category à la dev-texlive, something like sci-octave.
3.- Create a g-cpan-like program for this, preferably faster than the 
unexistent cran one.

My vote is for option 2. Comments?

Juan

overlay move to git

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hi all,

We are planning to  switch the science overlay from subversion to
git.
It will allow faster work flow from local overlay to a master one, which
also may attract more contributors. Many overlays are now switching
to git.


Thanks,

Hi Juan,

Thanks much for your message and all your hard work. We had a long time
ago agreed to go with 3., simply because of the fact that the
octave-forge.eclass does most of the work at this point and there is hence

Ok, must be useful then. Now, does anyone have a pointer to a short and
concise documentation that tells me how my work flow changes and all the
spells I have to cast e.g. when version bumping one of the packages?
Because I’ve no previous experience of git or of any DVCS’s.

But, IIRC, g-cpan is used mainly for makind ebuilds for perl packages, 
because there are a lot and they are in their repository, with their 
deps and everything. octave-forge packages are hosted in sourceforge as 
regular tarballs, they are updated and maintained by the same group of 
people, there are only a bunch of them, and they don't have their deps 
listed anywhere but in their webpages. I can't see how a g-cpan-like 
app can help us with this.

sys-cluster infiniband , mpi related soft. update request

Hello, i've seen that Infiniband drivers and other related stuff, like 
MVAPICH2 and openib etc. are a bit outdated. Recently i started 
administering a HPC cluster for molecular dynamics simulations (for ex. 
gromacs) from HP and found, that it works best on gentoo ;) . But i need 
most recent, fastest infiniband and mpi software for my work. 
gentoo-science overlay, if it comes to infiniband, doesn't work at all, 
i had to change some ebuilds to make them compile and work, but still, 
have some problems with MVAPICH2.

Please sys-cluster developers, if it isn't too much work, update ebuilds 
to open fabrics OFED 1.4 , MVAPICH 1.2 etc. (all dependencies). Or 
please, give me some instructions how to publish my modified ebuilds 
that, at least works (on contrast to openib-1.1.ebuild from overlay ;) )

best regards, Janusz

Hi

I'm going update openib for gentoo to 1.4. And also i use gentoo cluster with 
IB for molecular dynamics with gromacs. =)
BTW seems openmpi wiorks wit IB too so i gonna update it 1.3

Re: sys-cluster infiniband , mpi related soft. update request

Great news, thanks. I can't wait to see those packages updated.
AFAIK most important ones, that need to be updated are openib , 
openib-drivers , openib-files end their deps.

What about openib-mvapich2 ? It's something different than just 
'mvapich2' package? Do we need another mvapich?

And the last thing, should i use any Infiniband related option i Kernel 
configuration? Or maybe i should turn off all kernel IB-related stuff 
and use only those from OFED?

I personally use in kernel drivers.
This at least works with kernels 2.6.24-2.6.28

Switch is done [1].

For users only layman/playman, you might have to resync/readd the
science repo.

For contributors, please read Gentoo git docs [2]. Also the git web site
has many good docs. 

Thanks,
