I have just fixed the problem flagged up in comment #17, have cleaned up the code somewhat and am just turning my attention to module procedures. I expect to get the whole lot sorted in another day or so. As to the options for its use, I need to check out where we are with the testsuite. As you are aware, there are a number of problems there that I will have to turn to next. My inclination is to get the patch to full functionality but to leave it as an experiment for just a little while longer. It's good news that cp2k is now OK - did the performance improve?
