[Pw_forum] segmentation fault

[Vishal Gupta]

Hi,
I've been running an SCF calculation for a fee Ni system on High
performance cluster but no matter how many processors I choose to run it,
it always leads to segmentation fault :-
mpirun noticed that process rank 0 with PID 6353 on node c7c exited on
signal 11 (Segmentation fault).
or excessive memory leakage.
I mostly chose 6-20 processors but I've tried it once with 40 also.
Input file :-
 &CONTROL
                 calculation = 'scf' ,
                  pseudo_dir = '/home/vishalgupta/GB' ,

 /
 &SYSTEM
                       ibrav = 0,
                         nat = 44,
                        ntyp = 1,
                     ecutwfc = 55 ,

 &ELECTRONS
                 mixing_beta = 0.7 ,
             diagonalization = 'cg' ,

Can somebody tell me where the problem lies ?
Thank you
