thanks Dr. Pavel,
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.
Regards,
A. Kumar

Subject: "OpenBlas" package instead of default "blas"
To: <wien@zeus.theochem.tuwien.ac.at>
Dear Dr. Pavel Ondracka,
In previous thread,
https://www.mail-archive.com/wien@zeus.theochem.tuwien.ac.at/msg18098.html
you advised to use OpenBlas package to extract best performance from
processor. 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%.
Configuration of my pc: i7-8700 (6 cores, 12 threads), 8 gb ram (can be
upgraded to 16 gb), fedora-28, graphic card (gtx...)
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.
Waiting for your expert advise,
thanks,
A. Kumar
