Hi Neill servers users,

We've resolved the logging in issue.

Let us know if you continue to have any trouble.

Best,

Jarod

Message-ID: <8086.128.147.0.41.1328310286.squirrel@webmail.cs.cmu.edu>

Hi Lab,

Some of you may not know this, but I have been out since Tuesday and
basically living at Hamot Hospital in Erie supporting my family with my
father's open heart surgery.  Clinically, he's doing well, but he has been
quite miserable through the whole ordeal.  He really is doing well though.
 Thanks for all of your concerns.

Anyhow, as a result of this surgery and the toll it has collected from me
and my family, I have been less than responsive to some of your requests,
and for that, I'd like to apologize.

Please be sure to CC Jarod Wang <donghanw at cs.cmu.edu> when requesting help
from now on.  Jarod is a very friendly guy who is taking the reigns of
Sysadminship from me as I make my move to Arizona.

February 16th is my final day at the lab.  You should now start getting
into the habit of asking Jarod <donghanw at cs.cmu.edu> and I both for help
when you make a request.

Best Regards,

Mike

Subject: [auton-users] two interdependent DLLs in 64-bit MS-Windows?
Message-ID: <47874.128.2.176.180.1328569022.squirrel@webmail.cs.cmu.edu>

Hi gang,

I've got a crisis that I'd appreciate some help with,
from someone who knows MS-Windows way better than I do.

We currently have a single DLL, named tcube_java.dll,
that encapsulates all of the Auton Lab C projects
used by the T-Cube Web Interface.  We need to be able
to split this into two separate DLLs, e.g., no_sources.dll
and sources.dll, where the former contains callable
routines from projects where the user DOES NOT have sources
(but does have .h and .obj files), and the latter contains
routines from projects where the user DOES have sources
(.h, .c, .obj).

One problem is, these DLLs are interdependent.  For example,
extra (sources) depends on draw (no sources) depends on
utils (sources).

For extra credit, explain how to have Tomcat 6 on Windows
serve the sources.dll file, which in turn makes use of
the no_sources.dll file.

Help!  And Thanks!  We literally need a solution to this
by tomorrow morning.

- John O.

In what seems to be a repeat of the last outage, we are down again.

What we thought was a failed hard drive in one (rather aged) server has 
turned out to be a more systemic problem with that server.  As the 
server (or motherboard therein) has proven itself to be unreliable, we 
will be working to get the server or motherboard replaced today.

I expect it will be a matter of some hours before this is finished.  We 
should be back up and running by or before noon.

Please stay tuned for updates.

Subject: [auton-users] CPU Resources are Almost Maxed
Message-ID: <4F352E44.4020004@cs.cmu.edu>

Hi Lab,

In recent days, Jarod and I have noticed heavy use on the compute nodes. 
  We've also noticed that some nodes have many more jobs running than 
there are processors available on those nodes.

Please be courteous to other users and check the status page at 
http://www.autonlab.org/status (or at least run top) prior to launching 
your jobs.  Launching more jobs than there are available processors 
reduces overall throughput for everyone on the node.  The number of 
processor cores available on a node is listed on the status page in the 
denominator of the LOAD.

Also, a note for Neill Lab users.  If your jobs fit on a Neill Lab node, 
you should always prefer those nodes before using general purpose Auton 
Lab nodes.  You should do this because general Auton users can't access 
the idle Neill Lab nodes, whereas you can.

Best,

Mike

Hi lab,

LOP1 will be rebooted on Saturday, Feb. 18, at 8AM because of
essential system maintenance.

Please save your work and log out from LOP1 by then. During the down
time, you can use LOP2 to access lab's machines.

If this is a problem,  please let Jarod know as soon as possible.

Thanks,

Hi lab,

LOP1 is back online. Please check your jobs.

The incident is due to misplaced compute jobs on LOP1 and the jobs
overloaded the machine.
Please use LOP1 and LOP2 only for a passthru. Please view
http://www.autonlab.org/status to find an appropriate node to run your
compute jobs on.

Let me know if you have any problems.

Thanks,
