[Pw_forum] el-ph calculations

[Iyad AL-QASIR]

Actually, I have no problem with k-points parallelization in case of scf
calculations.

The problem is when running *.ph.in using ph.x ( with elph=.true.,)- in
this case I have to set npool =1 so the calculations will continue-.

I will try the Al example in the new version and let you know. Actually I
was running this example ( example07 in espresso example directory) using
espresso-4.0.3 and I had the same problem of using more than pool.

Many Thanks
IYAD
