May be it will be better if we can choose combinations mpi_imp/compiler
for example
mpi-openmpi-gcc
mpi-openmpi-intel
and so on
for now it can be done manualy specifing CC, Fc and so on env
may be it will be better if it will be done from empi?

Thanks for trying them out, I'm hoping someone else finds them as useful as
I

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 LD_LIBRARY_PATH "${lld}"
-setenv ESELECT_MPI_IMP="${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, <a class="moz-txt-link-freetext" href="http://dev.gentoo.org/~jsbronder/empi.xml">http://dev.gentoo.org/~jsbronder/empi.xml</a>. 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 ;)
