on 05/04/10 i opened up an additional 5 interactive nodes for use. There are still 2 more coming. This will spread out the load across more machines.
There's also a change with the mounting structure on the interactive nodes as well.
You can still mount a single experiment with lnexp ... but now you can mount an entire share with the command mntshare.
For example, if your data in on Fatt you could continue to access it with "lnexp MYEXP.01", which will in turn mount only your experiment, and you'd access the server through ~/experiment/MYEXP.01
However, if all your experiments are on fatt, you can now mount the whole data server with "mntshare //fatt/data". You can access all your data on Fatt through ~/net/fatt/data.
When you are prompted for your password to mount the data server its your WINDOWs password (since thats what is associated with the biac servers)
I just made a change to the interactive nodes that could be relevant for some.
The interactive nodes are the only ones with an actual local disk. Now the local disk is mounted and writable at the label "/scratch".
So if you are doing things that require writing data on the interactive nodes, it could be faster to write them locally, them move them to your storage server (ie: writing intermediate files/results).
Again, this is only relevant to the interactive nodes ... none of the compute nodes have local disks.
more interactive nodes
