[Pvfs2-users] Re: Is pvfs-2.6.0 use the compute nodes cache?

[Murali Vilayannur]

Hi Jiang,
As Rob mentioned there is no plan to utilize the compute nodes memory
as a cache for general purpose accesses.
I am still testing a patch that will utilize the page-cache
efficiently for immutable files (i.e. files that are explicitly tagged
as not being changed). Hopefully, once I am done and it is reviewed,
it should be possible to cache files that are not being modified..
Likewise, using the page-cache for buffering requires a little bit
more infrastructure and will be an opt-in feature rather than a
general purpose thing. However this is likely going to take a while
...
thanks,
Murali
