I've tested your new version of matrix.comp. It works and produces the same matrix outputs as I had before. However I have some comments

A remaining problem is the non-existing symbolic links like ounfmeta.inp which creates problems :
grep: ounfmeta.inp: No such file or directory

I recommend to add the error checker on the first line :
#!/bin/bash -e

Also, this line is not considered correct in new bash version :
cases=$(find . -maxdepth 1 -type d -name "work*" | grep -v work_oasis)
it should be replaced by :
cases=$(find . -maxdepth 1 -type d -name "work*" -and ! -name "work_oasis*")

Another correction would be to replace this section since oasis is now compiled inside each work sub-directory :

        cases=$(find . -maxdepth 1 -type d -name "work*" | grep -v work_oasis)
        # skip to next tst if no work directory
        echo 'run : ' $cases
        if [ -z "$cases" ] ; then
          echo "skip"
          continue
        fi

and replace it by :
cases=$(find . -maxdepth 1 -type d -name "work*")

For the
grep: ounfmeta.inp: No such file or directory

my hope was that the update to the run_test would actually fix that. Perhaps this needs more testing? If you remove ounfmeta.inp from your directories (which the run_test should now do for you moving forward), do you still have this error?

I added the -e in matrix.comp

I think I updated the cases issue, but let me know if you don't think that's correct or it's not working.

ok I didn't rerun the test so that's why I still have the ounfmeta.inp.
I've tested successfully the new version
