Title: Power and Cooling of HPC Data Centers Requirements


1
Power and Cooling of HPC Data Centers
Requirements
Roger A Panton Avetec Executive Director
DICE rpanton_at_avetec.org
2
Background and Objective
  • Avetec is under contract to evaluate power and
    cooling requirements for HPC data centers
  • To survey power and cooling constraints and
    solutions, both current and future
  • From representative HPC data centers
  • Vendors including HPC systems, equipment and
    facilities
  • Avetec contracted with IDC to conduct a survey
  • Current power and cooling situation
  • Planning in place to address requirements
  • Forecasted solutions in the next three to five
    years

3
Survey Sample and Methodology
  • Survey includes 41 respondents
  • 28 HPC data centers
  • 13 vendors of products and services
  • Response rate was approximately 20
  • Respondents were from US, Europe and Asia
  • HPC data centers were selected from the Top500
    list
  • Centers selected fell between number 50 and 250
  • Interviews were conducted by phone or in person
  • Respondents had the option to complete the survey
    on their own

4
Initial General Findings
  • HPC data centers averages
  • Available floor space about 26,000 ft2
  • Used floor space about 17,000 ft2
  • Cooling capacity 22.7 million BTUs or 1,839 tons
  • Annual power consumption 6.356 MW
  • HPC data centers costs
  • Annual power cost is 2.9 million or 456 per KW
  • Ten sites provided the percentage of their budget
    spent on poweraverage was 23
  • Two-thirds of the sites had budget for power and
    cooling upgrades
  • Average amount budgeted is 6.87 million

5
Initial Key Findings
  • Study revealed wealth of information
  • Key findings will be summarized in the following
    four areas
  • Current Situation
  • Challenges and Expansion Constraints
  • Current Approaches
  • Future Solutions and Technologies

6
Current Situation
  • Over 96 of the centers consider green design
    important
  • Majority of sites expect power and cooling to
    impact future HPC center planning
  • Majority of respondents have studied or
    implemented greener operations
  • Most centers have used software models to analyze
    heat flow and/or power consumption
  • Approximately half of the centers paid for power
    and cooling out of their budgets

7
Challenges and Expansion Constraints
  • Majority of centers are starting to consider
    power and cooling efficiency equal to or more
    important than HPC computing performance
  • Power and cooling issues are becoming the biggest
    barriers to expansion and upgrades
  • HPC vendors are starting to see power and cooling
    as a brake on performance

8
Current Approaches
  • Power and cooling costs are becoming a key factor
    in upgrade decisions
  • Majority of centers have accomplished an air flow
    analysis to improve air cooling efficiency
  • Use of chilled water for cooling is increasing
  • The power and cooling issues are being discussed
    across the HPC community, i.e. data center, HPC
    systems vendors, and processor vendors

9
Future Solutions and Technologies
  • Approximately two-thirds of centers plan to
    expand or build new data centers
  • About half of the data centers have or are
    planning to distribute HPC resources
  • Liquid computing is being considered as an
    alternative
  • HPC centers and vendors differ sharply on the
    likelihood of any game-changing cooling
    technologies emerging in the next 3-5 years

10
Viewpoint
  • Current status
  • June 2008 marked a new milestone the first Pflop
    HPC system made the Top500
  • Top500 lists the sum of the top 500 systems
  • 1993 Sum of top 500 equaled 1 ½ Tflops
  • 2004 Sum of top 500 equaled 1 Pflop
  • If current growth is maintained, sum will be 100
    Pflops by 2012
  • The balance between facilities and infrastructure
    to accommodate new systems does not exist
  • This imbalance leads to a policy question
  • What should the supercomputer community response
    be to restore the balance?

11
Policy Discussion
  • Should the community take a proactive position
    through collaborative discussions and then
    recommend a set of Public Policies?
  • To start the discussions should
  • The Federal Government establish a timeframe and
    fund the following research areas
  • Invest to maintain the current performance growth
    in HPC?
  • Invest in new cooling technologies to improve
    efficiencies?
  • Invest in low power higher performance
    processor(s)?
  • Invest in new material research for chips?
  • HPC data centers need to become more accountable
    for power and cooling consumption

12
Join Us to Learn Other Findings
  • Findings were extensive and cannot be fully
    covered today, such as
  • What alternative approaches are you exploring to
    meet future power cooling requirements?
  • Describe any new power cooling solutions expect
    to implement in next 2-3 years.
  • What special cooling methods do you expect to use
    in the future?
  • Future HPC system acquisition power cooling
    requirements.
  • And more!
  • Final study results will be unveiled at DICE
    Alliance 2009 on May 20 along with a panel
    discussion with some of the study participants
