Dear Haseeb,
1. the yambo compilation by default is in single-precision unless you do not include the "--enable-dp " option in the configure.
2. You have many k points so parallelizing over k should be the best strategy
3. Your calculation seems successful, the kernel has been written to the disk:
Code: Select all
[WR./BSEBnds_153-170_low_range_0-3//ndb.BS_Q1_CPU_0]
Actually I do not know why there is not the estimation time of the BSE kernel construction in the log files, anyway, the code spent more than 9h in the kernel building:
Note that you are using very low parameters in the kernel:
Code: Select all
|RL vectors [exchange]: 183
|RL vectors [correlation]: 75
In general, note you are dealing with a massive calculation (160 occupied bands and 976 k points), such calculation needs many resources. I do not know exactly what system you are dealing with (some complex bismuth tungsten oxide) , but maybe you can inspect if it is not possible to reduce the unit cell and if there are symmetries (in the present setup you have no symmetry) that for some reason are not taken into account by QE, this will help a lot.
Best,
Daniele
