Dear all,

I am using Yambo with QE 6.3 (GPL Version 4.2.1 Revision 110. (Based on r.14778 h.7b4dc3 MPI Build) and I encounter a strange problem when using Bash
's heredocs (cat >yambo.in <<EOF...) which I use for parameter optimization. When using Yambo interactively everything works but for convergence tests this is rather cumbersome..

I am only doing simple yambo -o c optics on graphene and I cat >yambo.in <<EOF the input file with simple $variable replacement. When I do this, yambo only runs through the initialization step but then stops just after [04] optics

it creates a big empty core.XXXX file but writes nothing in the corresponding LOG file

 <01s> P0010: Reading dip_iR_and_P_fragment_15

in the cluster error file it complains that a file is missing (but the file is there and it works when I run yambo interactively)

Code: Select all

[ERROR] STOP signal received while in :[04] Optics
[ERROR] File ; Variable DIP_iR_k_0274_spin_0001; NetCDF: Not a valid ID

is there something to do when using bash/pbs to run yambo non-interactively?

Thanks in advance for your help!

Chris

Dear Christoph,

is there something to do when using bash/pbs to run yambo non-interactively?

I would say no. T
The same, or similar problem was reported here:
viewtopic.php?f=13&t=1493&p=7127&hilit= ... d+ID#p7127
I do not remember exactly what was the source of the error, anyway, it was fixed in the more recent releases. I suggest you to update to a more recent
release.

Best,
Daniele

Thanks Daniele,

it seems to be working now!
