Yes, a fast file system. NFS via Ethernet may still be usable as long as
you do not have heavy or frequent I/O. Writing via NFS is especially slow.

Dear Dr. Giannozzi,
By the expression "parallel file system", you meant fast file systems
such as LUSTRE, not NFS via ethernet, right?

I didn't remember correctly: it is still implemented. As I mentioned
earlier, though, it is expected to work only for a subset of all possible
use cases. In particula

Dear users,
P.S. to the previous post:
1. To execute with multiple machines, outdir needs to be NFS-mounted
in order to be visible from all processes.
2. In nowf case, wavefunction files exist, but 0KB in size.

Dear QE users,
To lessen I/O with neb.x, what should I do? The 'outdir' grows really
fast. I want advice from experienced users or devs.
Issue:
Although the image parallelism (neb.x -ni $NumOfNodes) is scaling well
with the number of nodes even with gigabit ethernet, massive I/O to
'outdir' is ob
