<div dir="ltr"><div>thanks Dr. Pavel, <br></div>I have installed "openblas" package, changed R_lib path to "-lopenblas". Also utilizing K-poing parallelization. I didn't use "-ftree vectorize " option as i do not know how to do it. Overall satisfied with the system's performance. Thanks for the support.<br><div><div><br></div><div>Regards,<br></div><div>A.

Since i was having problem with wien2k installation, so i went with Dr. Gavin's set of instructions (for lapack devel package). Now i want to speed up the wien2k execution (simple oxides too take much time). Further i noted that at a time, only one thread remains 100% busy, rest threads shows load level 1-5%. <br></div><div>Configuration of my pc: i7-8700 (6 cores, 12 threads), 8 gb ram (can be upgraded to 16 gb), fedora-28, graphic card (gtx...)<br></div><div><br></div><div>I understand that "openBlas" need to be installed and set R_path to -lopenblas. I also want to utilize thread level parallelism if it boosts the processor's performance further by a factor of >= x1.5 times. <br></div><div><br></div><div>Waiting for your expert advise,</div><div><br></div><div>thanks,<br></div><div>A.
