Comment (by Roland Haas):

This was discussed for a bit in today’s ET call. Is there a public cluster where this happens and that could be used for testing? Most the XSEDE systems would be fine as well as SupeMUC at LRZ. A less convenient solution would be a pointer to where one can download Intel’s OneAPI and compiler these days.
