You got:
*calculating QTL's from parallel vectors*    !!! ????

If I understand the message correctly, it happens ONLY ?? when you calculate the qtls, not during scf.

So your command is either x lapw2 -p -qtl or you have QTL instead of TOT (FOR) in case.in2 ???

In "qtl" mode, lapw2 runs actually always in single (sequential) mode, the -p is used only to indicate that it should use the parallel vectors, not the sequential vector. And before lapw2 actually states, it executes a vec2old_lapw command to collect all parallel vector files.

Maybe here is the problem, because vec2old uses
set remotecp = scp
and most likely on your cluster scp is not allowed.

Edit vec2old and put in the proper remote copy command for your cluster.

If this does not help, put a -xf in the first line of lapw2para (and vec2old), which gives you a long output, but from that you can follow what commands are actually executed and where the problem is.

Dear WIEN2k community,

I am faced with a problem, where the "*x lapw2 -p*" procedure on my cluster asks me for passwords to all the nodes it uses:
*
*
*calculating QTL's from parallel vectors*
*mpo...@wn0125.ib.trojan.kdm.wcss.pl's password:*

no matter what I do after i get:
*
*
*Received disconnect from 10.27.75.188: 2: Too many authentication failures for mpolak*

And it repeats for all the nodes that are used.

This only happens when i invoke "*x lapw2 -p*" by itself, the lapw2 within the flow of "*run_lapw*" correctly uses the passwordless command for communicating between nodes that is specified as a part of the ./siteconfig_lapw for compilaton. I am not allowed to log in directly into nodes, so no password works, and even if it did, I want the job to run without my input, like all the other do, and use the ssh method provided with the compilation.

Is there a fix to this? If i'm not mistaken, this issue started with WIEN2k 16.1 and persists through version 17.1. All other parts i use (lapw0,1 and lapwso) work as expected with no problems.

I would really appreciate help in this matter.

Best regards

Maciej Polak
