Dear Daniele,

sorry for that. I was busy doing some repeated tests.
The still get netCDF errors (sometimes) when using an executable compiled with intel compilers. See attachment.
With gcc compiler and 12 cores the report file shows the same error as the intel one, but seems to run just fine with 8 cores.

Best Robert

Dear Robert,
yes, I think that netcdf and yambo need to be compiled with the same compiler.
Anyway, glad you succeed to run.
Off Topic in your input file:
Code: Select all
NGsBlkXp= 1            RL 

please note that you are considering a scalar dielectric matrix, this is a parameter that has to be bought at convergences.
