[Pw_forum] Problem with high accuracy and parallel ph.x

Dear PWscf users,

I have encountered a problem during parallel execution of ph,x

Actually the parallel pw,x performs good and without any error, but ph.x
does not work,
I lowered the kpoints and kinetic-energy cut-off and the problem solved and
ph.x works properly.
I need high accuracy in my calculation, so I cannot lower the kpoints and
How can I perform parallel ph.x without lowering the computational

Any help would be appreciated.
