internal ERROR: DEPLE: IRDMAX must be increased to 0

#1 Post by Danny » Wed Mar 13, 2013 11:57 pm

I get this error using vasp 5.2.11.
I have finnished the same calculation in a normal way, but when I increase the NGXF, NGYF and NGZF in get this error. (the values are of the order 600-900, and need to be this big, since I require a very dens grid for what I want to do afterward)

I tried setting LREAL=Auto, but that doenst change a thing, and when I set IRMAX and IRDMAX nothing changes.

when I grep for this keyword in the OUTCAR I find IRMAX=2091 and IRDMAX = -31490

What do I need to do to fix this problem?

Kind regards
Danny

The output looks like this:
(ignore the warning, we tested it for that machine, and it is wrong)

Code: Select all

 running on  128 total cores
 distrk:  each k-point on  128 cores,    1 groups
 distr:  one band on  128 cores,    1 groups

|                                                                             |
|      For optimal performance we recommend that you set                      |
|        NPAR = 4 - approx SQRT( number of cores)                             |
|      (number of cores/NPAR must be integer)                                 |
|      This setting will greatly improve the performance of VASP for DFT.     |
|      The default NPAR=number of cores might be grossly inefficient          |
|      on modern multi-core architectures or massively parallel machines.     |
|      Do your own testing.                                                   |
|      Unfortunately you need to use the default for hybrid, GW and RPA       |
|      calculations.                                                          |

and in the OUTCAR we see this:

Code: Select all

 grep IRDMAX OUTCAR_500
   max r-space proj   IRMAX =   6245   max aug-charges    IRDMAX= -31490



any suggestions?
