[auton-users] New Compute Node: LOW1

[Michael J. Baysek]

I am pleased to announce the availability of a new compute node, LOW1.

48 Opteron K10.5 cores @ 2.3 GHz.
512 GB (yes, GB) of RAM

After the SCS machine room power upgrade completion (currently rumored 
to be occurring over the December holiday break,) the machine will be 
installed into our rack.  For the time being, this node is situated 
outside of the machine room, and connected over VPN connection to the 
rest of the cluster.

You will notice network I/O being a bit slower as a result of the VPN 
and slower 100 Mbps network connection.  For now, you can mitigate this 
by copying your files and doing your I/O to the /scratch directory on 
LOW1, and copying the results back into your /auton directory.

The new node brings our compute cluster to a new milestone!  Auton Lab 
compute resources now include 200+ CPU cores for the first time (212, to 
be exact) and total RAM of 1 TB, including project machines.  This 
number does not include CPU and memory from desktops or infrastructure 
servers.

Enjoy LOW1 !
