Hi, No. mdrun reports the stride with which it moves over the logical cores reported by the OS, setting the affinity of GROMACS threads to logical cores, and warnings are written for various wrong-looking cases, but we haven't taken the time to write a sane report of how GROMACS logical threads and ranks are actually mapped to CPU cores. Where supported by the processor, the CPUID information is available and used in gmx_thread_affinity.c. It's just not much fun to try to report that in a way that will make sense on all possible hardware that supports CPUID - and then people will ask why it doesn't map to what their mpirun reports, get confused by hyper-threading, etc.
What question were you seeking to answer?
