The current funding situation here means it is difficult, if not impossible, to get HPC hardware from funding agencies. Even if you get a bit of money, it is just enough to get a new node. !!! It must be the heartbleed bug affecting your mail server ... :-) -- Nicholas M. Glykos,

Dear all, in some of the discussions here I came across the 'lifespan of a cluster' argument. What I was wondering is: how long is that in HPC for number crunching? Is it 3 years (end of warranty), 5 years (making good use of hardware) or longer? The reason behind that asking is: I got cluster
