Lots of changes for glogin and juwels
I haven't made a pull request before, but here goes. I've mostly worked on glogin and a bit on juwels. It took a long time to figure out that Intel MPI 2019 has serious performance issues on HLRN-IV Gottingen (glogin). As long as the launcher is set to "srun" I think my settings are optimal for the machine. I've also updated the file for juwels. Cheers!
