uses the QSW NIC to access disks via some file servers, uses local memory caching,
blablabla (you should be able to find a lot about this on the web),
and PFS is able to manage parallel access to file servers, that gives you more
throughput of course.

What about PC's clusters ? Here, our dear users use local disks ! They seem to be
quite happy,
(one day one of my colleague tried to install PVFS over SCI but it was a disaster),
so we are a little bit disappointed. Why HPC's vendors are doing efforts,
if most of the user's programs can use local disks + ftp at the end of their runs on a
distant file server ?

That's why I post my super naive email yesterday.

Are there some figures about PVFS perfs over SCI and/or Myrinet ?

Thansk,
