Hello Eloisa, sorry for the delay in the reply. For the records I did manage to compile and run ET on KNL (stampede), but I did not manage to run any benchmark with it yet. The current status is:
* intel-17: the compiler fails to compile Carpet and either gives an internal error or segfaults. * gcc-6.3: used to compile and run with Erik's spack installation (it is currently broken). I did not really manage to benchmark it since even a low-resolution TOV test did not run to completion (meaning less than 4 coarse grid steps) within 30 minutes on 4 nodes. This was using the current stable release of the ET (2016-11) and WhiskyTHC. You might have more luck with GRHydro / pure-vacuum runs.
