Why Mercury?
  • Mercury became the moniker
  • for the system because of the
  • association of Mercury with
  • Roman mythology
  • A god that served as messenger to
  • the other gods
  • and was himself the god of
  • commerce, travel, and thievery
  • (and eloquence).

e-mail info
  • Address to equipname at
  • No attachments can be sent to equipment aliases.
  • Easiest to send through MercuryWeb
  • May be sent from email (webmail) client, but must
    come from domain.

The NanolabComputing Environment
  • Activities in the laboratory are tracked,
    regulated, and accounted for with laboratory
    management software
  • called Mercury. Members use this software when in
    the lab by starting the program and
    authenticating into a
  • session. If the member has appropriate
    qualifications, they can utilize functions
    provided by the software to use
  • equipment, file reports, check activities, and
    execute a variety of other tasks.The most common
    way to use the
  • Mercury is on a remote desktop session from a
    Windows Terminal Server called CAPE2 (Common and
  • Environment). Additionally, some of the software
    utilized for laboratory operations is available
    through the
  • Marvell Nanolab web portal or MercuryWeb this
    includes reservations, qualifications, and member
  • Outlined below are some basic steps required to
    get started.
  • Logging In
  • The first step to using the laboratories is to
    logon to the CAPE2 (Common And Personal
  • server by starting a remote-desktop session from
    a PC in the reception area. Once logged in you
    will click
  • on a "Mercury" icon to start your session. When
    using the Mercury it is important to login to the
  • laboratory because It lets others know that you
    are in the lab. It initializes accounting
    functions.It permits
  • you to enable and disable equipment. It shows
    you the state of the lab equipment and allows you
    to file
  • problem reports.
  • 2. CAPE2 (Common and Personal Environment)
  • CAPE2 terminals provide a Windows environment
    and access to a Mercury session. The CAPE2
  • acts as a hot desk. Your session will stay
    active as you move to different terminals in the
    lab. After
  • entering the lab and logging into CAPE2, you
    will need to login to the Mercury. When you are
    ready to

3. Mercury Overview Nanolab users will use
Mercury to enable/disable equipment and file
problem reports. This system starts up by
clicking on the "Mercury" icon on the CAPE2
remote desktop. Login by entering your user name
and password (your project will also appear on
the screen). The Mercury interface has selectable
tasks on the left pane and forms or tables on
the right pane. Tabs on the bottom and right side
of the interface allow you to switch back and
forth between various forms or tables. Most tasks
in the lab can be done by selecting the
"Equipment" task on the left side pane. On the
right side you will see a list of available
equipment. The status of the equipment is
shown under the status column. A green status
indicates that the equipment is ready to use,
yellow indicates a problem report has been filed,
but the equipment is still operational in a
limited manner, a red status indicates that the
equipment requires attention and is not
operational. If a row on the equipment list shows
a membername, it means that the equipment is
enabled by that member. The equipment table has
drop down menu labeled "Action". You can use this
menu to show your qualifications or refresh the
table. By selecting a row on the equipment table
and right-clicking, a pop-up menu will appear
with equipment specific actions such as
enabling/disabling, filing a problem report,
sending mail, or viewing qualified members. Other
tasks on Mercury operate in a similar manner.
Mercury has a companion web site called
MercuryWeb (accessible both through the Marvell
Nanolab web site and the Mercury Client). This
site allows you to make reservations, view
inventory, check equipment status, see who is in
the lab, and do various other tasks that may be
done outside the laboratory. Use the buttons
provided by MercuryWeb to navigate through its
features instead of the back button on your
browser. MercuryWeb is can be used from any
remote location. Mercury Client is available only
from the CAPE desktop.
4. Unix Windows Accounts Members are provided
with a computer account on a Windows Terminal
Server "CAPE2" and on a Solaris server cluster,
"silicon". The silicon cluster consists of
the following machines that members can
access silicon2.eecs.berkeley.edy, and  Members use
silicon2 to run UNIX utilities. Members use
mercury4 to run cpu intensive CAD programs such
as gds2tap.  Regardless of which server on the
silicon cluster you use, your home directory will
be the same. Members have a disk space allotment
of 200MB. Remote access to silicon2 and mercury4
is done with Secure-Shell.The CAPE account is
used by members while in the Nanolab.  Your CAPE
remote desktop provides access to the Mercury
program. See https//
rs/computers/cape2.html. Members and staff have
e-mail accounts addressed as Our systems forward member e-mail to
an external account they specify when their
account is setup (such as BMail, gmail, etc).
Please check your mail regularly because we send
out information pertaining to reservations, equip
ment shutdowns, and other important lab activity
via e-mail.  Messages may also be delivered
when logging into one of our systems. Please do
not ignore these messages because they may
contain information regarding safety and other
operational news for the Nanolab (in many cases
these messages are not relayed via e-mail).

6. Reporting Equipment Problems
Maintenance The cooperation of all labmembers is
required to keep our equipment up and running.
The computing systems in the Nanolab provide an
easy and efficient way of monitoring equipment
problem status and notifying the equipment
engineering staff when trouble arises with a
given machine. In the Marvell Nanolab Report
problems on Mercury (left click equipment name,
right click for drop down menu, select Report
Problems). Computers associated with equipment,
must not be modified in any ways. They are not to
be used for playing games, surfing the net or
storing labmember files. Do not install or modify
screen savers or wallpaper. Failure to follow
this rule will result in suspension from the
Nanolab. If there is an issue with an equipment
computer, file a FAULT report. Reporting When
you disable any system, the computer will prompt
you as to whether you have a problem to report.
Answering yes will automatically place you into
the problem-reporting program in which you must
describe, clearly and completely, the problem you
encountered. A comment like "machine doesnt
work" is not acceptable. Explain how the problem
showed itself, what you were doing when it
occurred, and what steps you took to correct it.
You can cc (carbon copy) the problem report to
anyone you think might want to see it, such as
other people in your group who you know may want
to use the system that day. It is not necessary
to cc problem mail to any staff members, as they
receive copies automatically. Once entered, the
problem report will appear on the screen whenever
anyone subsequently tries to enable this machine,
until a staff member clears the problem. Also, it
will be mailed automatically to the
engineer-in-charge. Remember, the more detailed
the description of the problem the more quickly
and efficiently the engineer will be able to
isolate and correct it. Once the problem has been
logged in the computer, you may try to locate the
engineer-in-charge by calling the office on the
intercom if your need of the machine is pressing.
Equipment Power Unless there is a
life-threatening emergency, NEVER shut off power
to a machine! This may cause a system failure.
