Computing NeedsDriven by the stages of the
research process
Each stage has different computing needs.

• Identify Phenomena
• Develop Hypothesis
• Organize Collaboration
• Propose Experiment
• Get Approved
• Obtain Funding
• Plan and Design Experiment
• Build / Install Equipment
• Acquire / Record / Store Data
• Analyze Data
• Obtain Results
• Publish Conclusions

3
Computing Facilities

• The needs are addressed by various facilities
• Networks
• Mass storage robotics / tape drives
• Large computing farms
• Databases
• Operations
• Support
• This presentation will focus on mass storage and
  computing farms.

4
Acquire Data

• Acquire data events 300KB/event
• A filtered event is passed on every few hundred
  microseconds.
• Raw data 100s GB/s Filtered events 10 MB/s.
• What gets through is recorded to disk and
  eventually stored on tape in one of several tape
  robots.

Stored Data Presently Available
Data In Fermilab Robots

• 4 Petabytes of Data stored in the Fermilab
  Robots
• 4 Petabytes 4,000 TB 4,000,000 Gigabytes or
  about 100,000 Disks on your PC.
• Equivalent to a stack of CDs
• nearly 10 times as high as the Eiffel Tower

Vital Statistics

• FNAL has gt10,000 network connected devices
• They are connected by gt1,000 miles of cabling
• There is more than 200TB of disk spinning now
• We have over 4 PB of data on tape
• Half of it is less than 2 years old

9
Computer SecurityInsuring computer use as
intended

• The Internet is now 100 Million computers/users
  one in a million events happen every day.
• With the net somewhere on the net is always
  just next door.
• We are learning how to live in a world where not
  everyone is friendly.
• A recent demonstration of an unpatched Mac showed
  it was hacked in 2 minutes.
• We use automated scanning software to detect
  problems and follow up on any sign of a problem.

The CMS Experiment at CERN will begin in the
2007/2008 time frame. It will supply data via
Tier 1 facilities at Fermilab to researchers at
Tier 2 university locations.

US CMS Computing

• Fermilab is the host lab of U.S. CMS experiment.
• Fermilab hosts the project management for the
  U.S. CMS Software and Computing Program in DOE.
• U.S. Physicists participate in this research.

12
CMS Data Xfer FNAL to World

• The US CMS center at
• FNAL transfers data to
• 39 sites worldwide in
• CMS global Xfer challenge.
• Peak Xfer rates of 5Gbps
• are reached.

45 Sites Working together as a Coherent
Computing Facility
2500 jobs
20 Research Groups Sharing the Sites to Run
Compute Intensive Jobes
