It's terrific for that.

I used to construct HPC clusters of that general description when I
worked at VA Linux Systems and at California Digital Corporation, both
of those being Linux hardware vendors.

Your HPC clusters would of course live on a protect inside network.
Part of the reason for that is that NFS is a bit of a security risk.

OK, I believe you. You don't see it.

But I'm still not going to spend time arguing.
