Our new cluster aims to have around 300 compute nodes. I was wondering what is the largest setup people have tested NFS with? Any tips or comments? There seems no way for me to say if it will scale well or not.
I have been warned of performance hits but how bad will they be? Infiniband is touted as a solution but the economics don't work out. My question is this: Assume each of my compute nodes have gigabit ethernet AND I specify the switch such that it can handle full line capacity on all ports. Will there still be performance hits as I start adding compute nodes? Why? Or is it unrealistic to configure a switching setup with full line capacities on 300 ports? If not NFS then Lustre etc options do exist. But the more I read about those the more I am convinced that those open another big can of worms. Besides, if NFS would work I do not want to switch. -- Rahul _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
