[Pvfs2-developers] Distribution by hostname

not necessarily, I think it could be seperated also. I think the example I 
gave was similar to the way of passing in distribution parameters into MPI-IO 
some guys have implemented here...

a) put everythink into one string like 
DIST_HINT= "ioservercount=2;ioservers=node1,node4;dist=simplestripe;dist_stripesize=65536"
The advantage is that the whole string could be given as opaque value to the 
distribution processor. However, the separation is is not very good.

b) seperate hints completely so one hint for each of:
ioservercount=2
ioservers=node1,node4
dist=simplestripe
dist_stripesize=65536

I think in this case the distribution could take the whole set of hints and 
figures out which one it should use. However, the number of hints grows a lot 
(even if these remain on the client). Still I would prefer something like 
that.
