Don't use Intel Hyper threading. Unless something drastic has changed it gets in the way. Beyong that there is no single answer. For small problems k-pt parallel is better, perhaps 2 threads. For medium problems (10-25 unique atoms) mpi with/without omp is better. For a large slab (50+ unique)

Dear All, I am now using a machine with i7-13700K. This CPU has 8 performance cores (P-cores) and 8 efficient cores (E-cores). In addition each P-core has 2 threads, so there is 24 threads alltogether. It is hard to find some reasonable info online, but probably a P-core is approx. 2x faster

Dear Prof. Blaha, Thank you for your comments. Are the functions u and u-dot provided in some output file? Manual mentions different types of u and u-dot for the cases of Psi^LO and Psi^lo. Manual also mentions that u and u-dot are obtained by numerical integration of radial Schrodinger
