Hello Paul,
I’m working on the Juqueen IBM BlueGene/Q in Juelich. (http://www.fz-juelich.de/ias/jsc/EN/Expertise/Supercomputers/JUQUEEN/Configuration/Configuration_node.html)

Other simulations are still failing, even with the new Nek version 17.0. I directly copy the case folders between the clusters and only change the compilers in makenek and number of processors in SIZE, but the cases still work on Intel but fail on IBM.

I found an older case from a few months ago that is still working fine, so I copied its .usr file to one of the new cases and it still failed, so I am suspecting that the error might be related to the grid. The parameters in the rea file are also largely the same.
