  • 1. The Potsdam Institute for Climate Impact Research takes on smarter climate research The Potsdam Institute for Climate Impact Research (PIK) is a pioneer in interdisciplinary climate research. PIK scientists use climate model-Overview ing to study global climate change and its impact on ecological,The Need economic and social systems. High-performance computing (HPC) isTo perform comprehensive calculations critical to this type of modeling. One of the challenges involveswithin challenging climate models as drawing conclusions about small-scale weather changes and short-termscientists study extreme weather condi- weather patterns, since brief storms or periods of drought are too shorttions and their impacts for computer models that are normally used to calculate long-termThe Solution weather developments.To implement an IBM Cluster 1350 solu-tion based on IBM System x iDataPlextechnology—ranked #244 in the Pushing the limits of high-performanceTOP500 list and #59 in the Green500 list computingWhat Makes it Smarter During a recent project on extreme weather simulation, PIKAchieves 30 times the performance of researchers had to examine short-lived weather events, usingprevious computers, uses 25 percent comprehensive calculations to draw conclusions about when and whereless power than conventional solutions, extreme weather events would occur and what their impacts could be.and delivers industry-leading energyefficiency These calculations made very high demands on the institute’s IT systems, pushing their existing high-performance computers toThe Result their limits.

Processors are cooled via valuable data center space water-cooled cabinet doors. Since iDataPlex cabinets are not as deep as standard cabinets, less air current is needed to cool the nodes; the blowers therefore operate at lower speeds, which also reduces power consumption. iDataPlex also requires less energy than compara- ble x86 systems, decreasing cooling demand per megaflop of process- ing power. “Thanks to the IBM supercomputer, we were able to reduce power consumption by 25 percent compared to conventional solutions,” Kramer reports.Smarter Research Boosting climate impact research with green HPC solutions Instrumented Captures and integrates weather data into “ensemble simula- tions” that simulate an extreme weather event 20 to 50 times with slightly different input values Interconnected Connects data across the climate model process, from the importing of records and processing of calculations to the storage and backup of enormous results files Intelligent More precisely predicts weather events that have so far proven to be incalculable—extreme, short-term weather phenomena such as torrential rain or drought
