Dear WIEN2k, I have a system where there are 4 or 8 cores in one node. (http://www.csc.fi/english/pages/louhi_guide/hardware/computenodes)
All cores see the same disk space. System has Portable Batch System, Professional Edition (PBS Pro) Typically $PBS_NODEFILE contains only a name of a single node (or some name for a collection of nodes???) System setup is such that one cannot use #PBS -l nodes=8:oneproc (which is probably rude agains other users) but must use #PBS -l mppwidth=14 I would like to run k-point parallel wien2k in this system (and not mpi parallel). Is this possible? To me it seems that if I generate a .machines file # 1:login6:1 1:login6:1 1:login6:1 1:login6:1 1:login6:1 1:login6:1 1:login6:1 1:login6:1 1:login6:1 1:login6:1 1:login6:1 1:login6:1 granularity:1 extrafine:1 one does not gain in speed when compared to a single core.
