Parallel version (MPI & OpenMP), running on 2 processor cores
Number of MPI processes: 1
Threads/MPI process: 2
MPI processes distributed on 1 nodes
30431 MiB available memory on the printing compute node when the environment starts
Reading input from al.elph.in
Reading xml data from directory:
./aluminum.save/
Subspace diagonalization in iterative solution of the eigenvalue problem:
a serial algorithm will be used
IMPORTANT: XC functional enforced from input :
Exchange-correlation= PBE
( 1 4 3 4 0 0 0)
Any further DFT definition will be discarded
Please, verify this is what you really want

Because shifted q grid is used, q2r will not work !
Saving dvscf to file. Distribute only q points, not irreducible represetations.
