I'm researching placement algorithms for different large-scale filesystems
using trace-driven simulation, and I'm trying to write a simulator for the
PVFS simple stripe placement algorithm.
There's one detail I haven't been able to find in any documentation: how
the values for the base I/O node number, number of I/O nodes, and stripe
size are selected, by default, for each file.
So far I've looked through the docs on the website, the dev mailing list,
the 2000 paper ("PVFS: A Parallel Virtual File System for Linux
Clusters"), the document "PVFS2 Distribution Design Notes", and the simple
stripe placement code (dist-simple-stripe.c).
Where else should I be looking for these default settings?
Thanks,
