Hello all,

As you may notice that LOW1 has a faulty memory module; it needs to be
replaced by a new module. During the maintenance, all services on LOW1 will
be unavailable; the maintenance will take place *Apr. 12th through 15th*.
If this is a problem, please let me know at your earliest convenience.

If you ever saw following message on LOW1, you have already experienced the
memory issue.

low1 kernel: Northbridge Error (node 0): DRAM ECC error detected on the NB.

The maintenance is critical for resolving the issue, thus providing you a
reliable computing environment on LOW1. During the downtime, a series of
tests will be taken to identify the faulty module; due to the large memory
capacity of LOW1, 512GB, it takes longer to perform detection.

Thanks,
Jarod

Subject: [auton-users] Managing ssh key using keychain
Message-ID: <CA+N7t7PHh7HQ5pu4u=Cp6baPJzXuDPk+W3N9hE7tOGEWrNGWQg@mail.gmail.com>

Hello lab,

This message describes how to use keychain to allow ssh access from one
host to another without typing password or passphrase in secure way. It
comes in handy in many scenarios, such as cvs operations, ssh from lops to
low1.

It requires a private/public ssh key pair. You can check its existence by
looking into your ssh files, specifically, id_rsa.pub and id_rsa; by
default they are in

/auton/home/<user>/.ssh/
/neill/home/<user>/.ssh/
or /home/<user>/.ssh/

So you have your ssh keys ready (if not, check out this tutorial
http://www.autonlab.org/auton_intranet/skills/sshkeys.html)

Simply append following line to the shell startup file, .bashrc for bash
and zsh and .cshrc for c shell and tcsh.

eval `keychain --eval --agents ssh id_rsa`

That's it.

Let me know if you have any questions. Enjoy,

Jarod

Hi all,

This is a friendly reminder that LOW1 will be down tomorrow morning (Apr.
12th) through 15th for maintenance. Thanks for your attention.

Hi lab,

The LOW1 maintenance will be extended to Tuesday, Aril 17th. The extension
is necessary because the large volume memory, 512GB, on LOW1 needs long
time for testing program(memtest86) to detect the faulty module.

I apologize for any inconvenience that you may experience.

Thanks,
Jarod

Hi all,

LOW1 is up and running.

The memory stress test comes up clean. it is the case that Memtest86+
is not guaranteed to be able to pinpoint faulty memory, so I decided
to put the machine back in to production to see if the error comes up
again during normal operation.

Best,
Jarod

Hello lab,

The Matlab has been upgraded to R2011b on all compute nodes. Just use
command--matlab--as you normally would do; and you are ready to go. In case
it fails to find the path, please add the following path to the PATH
variable
/auton/software/bin/x86_64

The complete list of available toolboxes can be found at following page.
http://www.cs.cmu.edu/~help/software_licensing/software_licenses/toolboxes.html

The previous version--R2010b--is obsolete but will continue to be available
for a few months. To launch it, use command--matlab2010b.

Best,
Jarod

Attention Users:

The LOU1 compute node had to be rebooted unexpectedly due to a process
which overloaded them machine and caused it to stop responding to the
world. Any processes or sessions on that machine were killed. It happened
on Apr 19th, around 10:20pm. Please check your jobs.

Thanks!

Hello lab,

The R has been upgraded to 2.14.2 on all compute nodes, including neills.
Simply type command--R--as you would normally do; and you are ready to go.

Old versions--R 2.13 and R 2.12--are obsolete but will continue to be

and R_2_13 on any other compute nodes.
