[Pw_forum] memory allocation failed

[gmonaco at unisa.it]

Dear all,
I have tried several times to make phonon calculations on a large cell. While
the program terminated using some pseudopotentials, upon a change of basis a
memory allocation error was obtained. Can anyine help me?
Thanks
Guglielmo

The working pseudopotentials are:
 C 12.00  C.blyp-mt.UPF
 H  1.00  H.blyp-vbc.UPF

The problematic pseudopotentials are:
 C 12.00  C.pz-rrkjus.UPF
 H  1.00  H.pz-rrkjus.UPF

The last lines of the phonon calculation output are
