Paolo,

I have attached to my email a file containing the list of the different
files contained in the "outdir" directory (which in my case is tmp)

You will see that *.igk_nproc *.wfc_nproc (nproc=1,2,3...64) files
do exist... together with a lot of others..
These files do not exist in the case of wf_collect=.false.

Let me also add that this test calculation contains 128 k points
and was run on 16 nodes and 64 processors.
