The super computer is highly expensive and you only get time there after you've made a official proposal and a commission has granted you're request. So while some of the data lies there in the shared fs (the GPFS),... people also want to process the data from the normal Linux cluster (where getting computing time is far more easy)... so they somehow need to access the data which is done via the NFS exports. Don't get me wrong, Trond, I'm not saying that this is the only or best solution... I say this is how things are done in reality. Obviously they must have found some workaround now... but I just wanted to point out that there *are* some use cases, whether they're perfect or not.
