Hello,
I'm beginning to give empi/eselect-mpi a try. Bravo, Justin, for making
these!
Thanks for trying them out, I'm hoping someone else finds them as useful as I
have.
It is planned to be part of the Gentoo Clustering LiveCD ;)
I've run into one bug in eselect-mpi that effects csh users (a popular
shell where I work). There is simply one setenv line that has bash syntax
rather than csh syntax. I already submitted a bug: its bug 226105.
Here is the patch to fix it:
================================================
--- files/mpi.eselect-0.0.3 (revision 1137)
+++ files/mpi.eselect-0.0.3 (working copy)
@@ -161,7 +161,7 @@
setenv PATH "${binpath}"
setenv MANPATH "${manpath}"

-setenv ESELECT_MPI_IMP="${1}"
+setenv ESELECT_MPI_IMP "${1}"
EOF
echo "Remember to source ${user_ev_sh} or ${user_ev_csh}"
================================================
Fixed in eselect-0.0.3-r1. Also found another mistake when setting PATH for
c shells and fixed that as well.
Also, in the README file, the for loop in step 6 is incorrect:
for i in $(ls ${HOME}/.env.d/*); do
source ${HOME}/.env.d/${i}
done
Results in:
-bash: /home/bgreen/.env.d//home/bgreen/.env.d/mpi.csh: No such file or
directory
-bash: /home/bgreen/.env.d//home/bgreen/.env.d/mpi.sh: No such file or
directoryA
Also fixed. You might also want to check out the doc I've been working on
lately, http://dev.gentoo.org/~jsbronder/empi.xml. Hopefully it's a little
more up to date.
Have to remember that one ;)
On the system where I'm using empi, I've created files in /etc/profile.d to
source the user's .env.d files when they log in. What do you think about
having the eselect-mpi ebuild install these, so mpi users dont have to do
that part manually? They would instead just have to source /etc/profile or
/etc/csh.login after running 'eselect mpi'.
Love it, I had not even thought of using this mechanism before even though I
should have. It will also simplify switching from an mpi environment to one
without it. I'll try to get something checked into the overlay soon,
shouldn't be more than a few days.<
Keep us posted because I will definitely want that version!
Here are my versions of the files in /etc/profile.d:
==============
mpi-config.sh
==============
if [ -d ${HOME}/.env.d ]; then
for i in ${HOME}/.env.d/*.sh ; do
. "${i}"
done
unset i
fi
==============
mpi-config.csh
==============
if ( -d ${HOME}/.env.d ) then
set nonomatch
foreach i ( ${HOME}/.env.d/*.csh )
source ${i}
end
unset i nonomatch
endif
==============

Thanks again for testing and your comments, they're much appreciated.
Yeah, thanks you both, multi-mpi-on-1-system has always plagued me too ;)
