Green Extreme Computing

Green Extreme Computing is about marrying business and environmental interests, with energy-conscious solutions that provide optimal performance while reducing their environmental impact. Overall energy efficiency can only be achieved by designing and selecting all infrastructure and IT components with energy saving in mind, from the start. That is why Bull is working on all fronts to minimize the carbon footprint of its current and future Extreme Computing clusters:

• Optimized IT components: each component contributes to overall energy efficiency
  
  
  • Processors with improved performance/Watt
  • Optimized processor architecture (multi-core, load-depending consumption)
  • Servers with reduced number of components
  • Lower consumption memory technology
  • High efficiency power supply units (92% power utilization in bullx R422 E2, versus 80-85% in conventional servers)
  • No Uninterruptible Power Supply unit needed
  
  
• Optimized rack and computer room cooling
  
  
  • Cool cabinet door with active monitoring and auto-adjustable fan speed – the efficiency of water-cooling at rack level
  • Optimization of chiller utilization – cooling with environmental air whenever possible
  • Intelligent computer room design – it has as much effect on electrical consumption as the efficiency of individual devices
  
  
• Optimized resource utilization
  
  
  • Systematic use of batch scheduler/resource manager
  • Use of specialized, high-efficiency processors whenever appropriate (such as NVIDIA Tesla systems)
  • Power management features, such as economy mode for unused components, integrated in cluster management suite
