[Pw_forum] projwfc.x meet error

[alamgir kabir]

Dear Jinxi,
I got the same problem few days back, and fortunately it is solved now. The thing is davcio is for reading from input and writing to the output, now if you scf calculation is done in different number of processor than your Projwfc.x than it get problem while reading from input. So please check if your pw.x calculation and projwfc.x caculation have same number of processor or not.
Thank you.

Dear Jinxi,

    davcio is the subroutine dedicated to input/output of restart files. The error code is related to the value of some internal variable when the code crashed and sometimes it might be useful to identify better at which point it stopped, but you shouldn't attach any special meaning to that number. Just check that your files are not corrupted and that you do things properly.

Regards,

GS

>>I don't understand completely what you meant here. The wavefunctions are needed by projwfc.x, you can't run this calculation if you don't have them. The wavefunctions are automatically written by pw.x at the end of the run. In some cases, you may need to use the wf_collect option (see input description in Doc/).
