stuck in caluclation of static inverse dielectric matrix

Deals with issues related to computation of optical spectra, in RPA (-o c) or by solving the Bethe-Salpeter equation (-o b). Includes local field effects, excitons, etc.

Dear Zhou,
your script seems to me to be correct.
Can you try to reduce the number of bands just as a test to be sure the problem is related to memory?
Best,

Dear Daniele
I would like to share my experimence:

I have fixed this issue. It is actually the issue of memory. In my submission script, I am launching intel's mpirun . But the mpirun is not able to pick up the options I set with #SBATCH. I switched to srun as "srun -n 192 yambo -F ..." and found that I could use more large memory per core in this way.

Thanks
