Thank you for your reading. 
The problem in the parallel is in a nlvdw level because i run the wien2k 
normally without nlvdw option (i run it locally on multi-cores PC), there is my 
.machines file : 
--------------------------------------------- 
lapw0: localhost:4 
nlvdw: localhost:4 

1:localhost:1 
1:localhost:1 
1:localhost:1 
1:localhost:1 

granularity:1 
extrafine:1 
--------------------------------------------------- 
and the errors : 

kamel@kamel-MS-7915:~/WIEN2k/nlvdw_test/t$ run_lapw -I -fc 1.0 -i 90 -nlvdw -p 
bash: lapw5: command not found

with the errors repeated as many as : t.output5_1 to t.output5_152, I mean 152 
times . 
So, is lapw5: command not found is an error or something is wrong as the lapw5 
command not executed.

Subject: Re: [Wien] Bugs : related to nlvdw calculations 

The third one is connected to prepare_xsw, and may have two sources: 

a) The .machines file. In the parallel case, prepare_xsw reads the lapw1 lines 
and can have problems because it makes assumptions about the format. You can 
use a format such as 
1:node1:4 

If you make it more than 4 you may have a problem, and 16 certainly fails. I 
got it to work by trial and error. 

b) Something else such as $WIENROOT not being exported to the python command 
that is launched. (This is a guess.)

Dear all, 
Recently, I found this bugs related to inclusion of the nlvdw corrention to the 
calculation of band structure of some material in WIEN2k 17.1 running at Linux 
system (intel Xeon Processor) with intel compilers. In the following I report 
the bugs with their errors and my proposed fixed bugs, if found. 
-------------------------------------------------------------------------------------
 
1- the initialisation of lmtmp integer array in SRC_nlvdw/calc_vvdw.F 

the error : Insufficient virtual memory 

to Fix : After the line 41 in SRC_nlvdw/calc_vvdw.F add : 
lmtmp =0 
and recompile a selected package : nlvdw 
-----------------------------------------------------------------------------------------
 
2- missing of XC_GGA_X_B86_R xc functional in SRC_lapw0/xc_funcs.h ( for 
example : if we use rev-vdW-DF2 correction ) : 
the errors : 
stop in lapw1 with : SELECT - error 
no energy limits found for atom .......... 
E-Bottom ........... 

to Fix : just add to SRC_lapw0/xc_funcs.h this line : 

#define XC_GGA_X_B86_R 41 

-------------------------------------------------------------------------------------------
 
3- The parallel run with nlvdw correction doesn't work for me 
with the errors : 

lapw5 : command not found 

any suggestions. 

Thanks in advance
