[Pw_forum] serial run when parallel intended

[Omololu Akin-Ojo]

Hi,

I was aiming to run QE in parallel but I see the following message in
my output file; what am i doing wrong?

     Subspace diagonalization in iterative solution of the eigenvalue problem:
     a serial algorithm will be used

Why is QE using a serial algorithm? I am using openmpi and QE
recognizes the number of processors correctly:
     Parallel version (MPI), running on     8 processors
     R & G space division:  proc/pool =    8

I could give more info if needed.

Thanks in advance for any help.
