So we know we have a need for home directory disk space. But if we got more nodes, which would they be? So here is a look at that. The 2-3 week period from Christmas to end of first week of Jan, represented by no jobs running/pending, was when the electrical work was done on our building.
|First we look all queues combined. The tremendous spikes are from a single user who submits hundreds of programs overnight which run very fast.|
|The light-weight nodes, 8 gb per dual-quad PE1950|
|The medium-weight nodes, 12 gb per dual-quad PE1950|
|The heavy-weight nodes, 16 gb per dual-quad PE1950|
|The heavy-weight nodes with fast local disk space, 16 gb per dual-quad PE1950|
|The light-weight infiniband connected nodes, 8 gb per dual-quad PE1950|
|Next the sharptail cluster, a mix of 112 12 gb dual Opteron nodes and 114 24 gb dual Opteron nodes (the Blue Sky Sutdios donated hardware)|
