Desktop Options at Dzero


Computing available to all users:

All users will have access to the the Central Analysis Server (D0MINO)
which will be a 192-processor SMP machine with
20-30 TB of disk. This machine may be used to run all Dzero
programs and access all Dzero data and databases. The machine
has been sized to handle the entire projected load of
data analysis for Run II. Users will have disk space on this
machine for storing their Ntuples/RootTuples and for doing code
development as well as running their analysis programs.
Users will also have access to the Project Server machines.



Option 1:  Desktop capacity for telnet, office programs, and web browsing

Purchase an inexpensive PC running NT or Linux
and add it to the appropriate D0 cluster.
Use this machine to telnet
to the Central Analysis Server (or to a Project Server as appropriate), to
run Microsoft Office Products (or Linux products of similar functionality),
and to run your favorite internet browser. This machine should have
an ethernet card and a CD ROM or CD RW drive.

Note that some machines will have capabilities between Option 1 and
Options 2 or 3.



Option 2:  Desktop capacity for Data Analysis and Code Development,
           office programs, and web browsing with Linux

Purchase a more powerful PC running Linux.
This machine should be a minimum of a 450 MHz PC with 256MB of memory
per processor. It should have 18GB of disk or more for local storage
of Ntuples and Code. It should have an ethernet card.
It should a CD ROM or CD RW drive.
This machine will be part of the
Dzero Linux cluster. Home areas will be served so that your
login area will be the same on all machines on the cluster, and on the
Central Analysis Server (we may decouple CAS and Linux in the future if
this becomes a performance bottle neck.)
FNAL products and the Dzero libraries will also be served.
You will also be able to copy the Dzero code distribution to your
node if you choose.
This machine can then be used for doing analysis, storing
Ntuples/RootTuples, doing code development, and running the Monte Carlo.
It can also be used for any of the functions of an Option 1 machine.



Option 3:  Desktop capacity for Data Analysis and Code Development,
           office programs, and web browsing with NT

Purchase a more powerful PC running NT and make it part of the
Dzero NT cluster.
The hardware minimums are the same as Option 2. With this machine,
you will be able to participate fully in Level 3 development in addition to
the functions listed in Option 1.
Note that only Level 3 packages and the infrastructure necessary
to support Level 3 currently are released to NT, and we do not have the
resources to broaden this commitment to supporting the rest of 
the offline software on the NT platform.
