band parallelization

Hello all,

I was wondering if I should expect something in the log file that tells me how the bands are divided between the assigned processors for band parallelization (just like in k point parallelization where it is explicitly written how many k points are treated by each processor). Or in other words, if I am parallelizing 648 bands over 8 processors does the log/output file say that 81 bands treated on node 0, 81 bands treated on node 1 ......

Thanks for your time,
Mohua

look for npkpt npband npfft in the log file: these are the number of procs over which the kpt, band, and fft are spread over.
