[MLUG] Cloud Computing

[Patricia Campbell]

Well put Pascal!   The concept of the cloud is the future of parallel
and ssi computing.  You have the ability of instantiate a cluster in
minutess to do your heavy calculations, you pay for bandwidth &
processing time.  Then when you don't need it you pack up your image &
go home... much more cost and time effective than maintaining your own
cluster.   Any researchers on the list?
