Dear Pietro and Marcelo Albuquerque,
I followed your instructions and the job has done greatly. However. there
is something weird in the output file. When I set OMP_NUM_THREADS=64 and ran
mpirun -np 2 ...
in the output, the first lines were printed out twice.
Meanwhile, when I set OMP_NUM_THREADS=1 and ran
mpirun -np 40 ...
every line was printed out 40 times in the output file.
Something like this:
Self-consistent Calculation
iteration # 1 ecut= 50.00 Ry beta= 0.30
Davidson diagonalization with overlap
total cpu time spent up to now is 1934.7 secs
Self-consistent Calculation
iteration # 1 ecut= 50.00 Ry beta= 0.30
Davidson diagonalization with overlap
total cpu time spent up to now is 2017.0 secs
Self-consistent Calculation
iteration # 1 ecut= 50.00 Ry beta= 0.30
Davidson diagonalization with overlap
total cpu time spent up to now is 2027.3 secs
Self-consistent Calculation
iteration # 1 ecut= 50.00 Ry beta= 0.30
Davidson diagonalization with overlap
total cpu time spent up to now is 2062.5 secs

Self-consistent Calculation
iteration # 1 ecut= 50.00 Ry beta= 0.30
Davidson diagonalization with overlap
total cpu time spent up to now is 2069.4 secs
Self-consistent Calculation
iteration # 1 ecut= 50.00 Ry beta= 0.30
Davidson diagonalization with overlap
total cpu time spent up to now is 2070.5 secs
Self-consistent Calculation
iteration # 1 ecut= 50.00 Ry beta= 0.30
Davidson diagonalization with overlap
total cpu time spent up to now is 2089.3 secs
I am not sure whether it affects the calculation time (I think it may), but
it is really annoying. Do you have any idea about this problem and how to
solve it? Thank you very much!
