[DFTB-Plus-User] large-scale calculations_output overflow records and "cannot allocate memory error message"

[khalfoun hafid]

Dear Ben, 
I try to calculate the electronic band structure for a large system ( 32000 atoms of  Carbon) . 

Unfortunately I meet the output overflows record similarly as already been discussed 
https://mailman.zfn.uni-bremen.de/pipermail/dftb-plus-user/2018/002794.html
I've desactivated the writing of the dftb_pin.hsd file in the parser options ( as recommanded  in https://mailman.zfn.uni-bremen.de/pipermail/dftb-plus-user/2018/002795.html )
, but the problem of the non ability allocation memory still persist even I reach the limit of the required memory in the calculating machine. http://www.ceci-hpc.be/clusters.html#lemaitre3
what should I do  ?Using another machine with greater amount of RAM ?

  

thanks ,Hafid
