Previously, epics 3.1.4 was used.
When I tried to change it to epics 7, the following problems occurred:

The only reference I can find to those functions is in this 2011 email where they were requested by ITER, but they have never been included in EPICS Base itself. The EPICS community does have an external support module called MCoreUtils which provides utilities for running EPICS on multi-core systems, but I think you may need to consult with any contacts you might have with ITER and/or CosyLab to know how to convert your existing code.
