Dear federico,
The error message is
error: Exceeded job memory limit
error: Step 5242.0 exceeded memory limit (130943908 > 128000000), being killed
If reduce the number of Kpoint, the calculated Band structure will be not smooth enough.
Thanks

Ö÷Ìâ: Re: [QE-users] Huge RAM required for HSE calculation
Hi.
Which is the output error message you get?
I am not too expert with HSE in QE, but I suppose the kpoints number is quite large.
Maybe try to reduce the number of kpoints to see if u reproduce the REM error.
Start with a small kpoint mesh and try to increase it gradually until reaching convergence, I would say.
HTH
With the best

Dear QE users,
Recently, I want to calculate the band structure by HSE method. However, the calculation will stop because huge RAM require. From the output file we know that:
Estimated static dynamical RAM per process > 8.46 GB
Estimated max dynamical RAM per process > 8.59 GB
Estimated total dynamical RAM > 1099.85 GB
I think 1099.85 GB RAM is so huge that it is not reasonable to afford.
BTW, our server is 2 nodes, 128 threads£¬ 256G RAM. The QE version is 6.3.
