Hey All,
I'm coding up a PLFS ADIO layer and I'm realizing that one drawback is
that codes can't leverage multiple ADIO layers. Is this a concern? I
guess no-one needs PVFS/PLFS since PVFS doesn't suffer from an N-1
problem. And no-one needs PLFS/Lustre or PLFS/PanFS since both PanFS
and Lustre have POSIX mount points. I just thought about this and was
wondering if there are other concerns that I haven't thought of.
Also, which is probably the best skeletal ADIO layer to use as a
template?
Thanks,
John
