You have to explain exactly what you are doing and what the jobs do or not.
a) How did you compile wien2k ? ifort or gfortran ??? Which blas ?
b) I do not understand your statement:
I have seen it directly from cpu monitor. The usage of
the cpus are 100% at all the 48 cpus (24 core). I have started 4
calculations & the cpu usage are as follows:
lapw1 2400
lapw1 600
lapw1 400
lapw1 100
So you had 24 cores, 6 cores, 4 cores and only 1 core on the 4 jobs ???
They are all different, aren't they ??
Why are you saying they use 48 (or 24 cores) ???
What is "cpu monitor" ???
What are the case.dayfile outputs telling you ???
I'd like to see the timing lines in the dayfiles.
The timing should be different for these 4 jobs ....
Eagerly waiting for your advice.

How did you find out that it has taken all 24 cores ?
