yambo stop without error

Concerns issues with computing quasiparticle corrections to the DFT eigenvalues - i.e., the self-energy within the GW approximation (-g n), or considering the Hartree-Fock exchange only (-x)

yambo stop without error

Dear All
I made an input file for GW calculation :
# __ __ ________ ___ __ __ _______ ______

# \::\ \ \:.\ \ \ \\. \ \ \ \\::(_) \ \\:\_\ \ \
# \__\/ \__\/\__\/ \__\/ \__\/ \_______\/ \_____\/

I use 512 processor in p6 machines but I didn't get any error. I know that the memoryis enough but I don't know why does it stop?

l_xxvxc_em1d_ppa_gw0_05 files is as follow:

Dear Ali,
the information you post are not enough to help you.
Anyway, just to start, try calculate your qp corrections for few
states around the gap, instead of all your 600 states!!!

Next, even if not at all related with your error: why using 600 states to build the screening and JUST 1 block(NGsBlkXp= 1 RL)!!!

Try to post us more infos, as the report file, as we can try to help you.

Cheers,

Daniele
