[Pw_forum] Memory usage by pw.x

[Guido Fratesi]

Dear all,

I'm trying to quantify the memory usage by pw.x: at the beginning of the 
SCF cycle the message "per-process dynamical memory:" reports the memory 
allocated at that time (clib/memstat.c), but this value is significantly 
less than the one I can see by monitoring the process by the "top" 
command, as more memory is allocated afterwards. Let me guess that 
calling again memstat later on, eg in c_bands, could provide one a more 
precise estimate, but maybe you can suggest a better approach, or 
correct me if I'm completely wrong.

Thank you in advance,
Guido
