Subject: [auton-users] Do you use VNC ?
Message-ID: <4AEF010E.8090909@cs.cmu.edu>

Hi Everyone. 


I know many of you have been using ssh tunnelling and VNC on the various 
compute machines in order to maintain persisting sessions. 


 From now on, VNC sessions will only be run on LOP1.  This is being done 
to reduce the statefulness of the rest of the compute nodes, and to 
further the resdesignation of LOP1 as the access node to the rest of the 
nodes. 


A major change with this new environment is that we will no longer be 
using the GNOME desktop as the desktop environment under VNC.  It is too 
heavy and provides needless functionality.  We will be using a 
lightweight window manager (WM) called Fluxbox as the default desktop 
unless software incompatibilities force us to use a different WM.


If you plan to use VNC to keep a persistent session on the LOPs, please 
email me.  I will setup the session in such a way (using a daemon) that 
your session will always be running on the same port, even after reboots 
of the server.  This will make it easier to tunnel the port since it 
won't change every time you start a session from user space. 

VNC will be set up by request only.  I will be using default screen 
resolutions of 1024x768 @ 16 bit color depth as the default.  If you 
prefer another resolution, please include that with your request.

Subject: [auton-users] Cleanup Required on BigPapa and userdirs
Message-ID: <4B0AC545.3040205@cs.cmu.edu>

Hi Lab,


We're again filling up on storage.  The new file server is not ready 
yet, so I need to ask you to do one more cleanup on your userdirs and 
BigPapa space before the holiday break. 


As a stopgap measure, I have temporarily removed and archived the 
following directories under /mnt/BigPapa/data.  


- biobase

- dpelleg_data

- sbns_data

- superCOS

- tangram

- viper

- xgda_datasets


We are still over 90% utilization on BigPapa, and 95% on userdirs, so 
please do your part to conserve space until the new server is ready.


Mike

Subject: [auton-users] LOT2
Message-ID: <4B130204.1020004@cs.cmu.edu>

All,

If you had a job running on LOT2, you will need to restart it.  The 
machine was erroneously rebooted by SCS operations just now.

Also, there have been a number of occasions where all the RAM has been 
used, but there were still free CPUs.  Please take special care to not 
overflow the memory on the machine.

Mike
