“The range of cooling options now available is testimony to engineering ingenuity. HPC centers can choose between air, oil, dielectric fluid, or water as the heat-transfer medium. Opting for something other than air means that single or two-phase flow could be available, opening up the possibilities of convective or evaporative cooling and thus saving the cost of pumping the fluid round the system.”
The First International Workshop on Heterogeneous High-performance Reconfigurable Computing (H2RC’15) has issued its Call for Submissions. Held in conjunction with SC15, the event will take place Nov. 15 in Austin, Texas.
In this special guest feature, Tom Wilkie from Scientific Computing World writes that software approaches to energy efficiency in HPC may yield unexpected improvements in the hardware of next-generation mobile phone networks. “Adept, a European research project addressing the energy-efficient use of parallel technologies, is expected to release a set of benchmarks that it has developed to characterize the energy consumption of programming models on different architectures.”
The HPC industry’s expanded use of liquid cooling was evident at the recent ISC 2015 conference in Frankfurt. To learn more, we caught up with Steve Branton from Asetek.
“Data centric workloads are growing in importance in high-performance computing and, in an industry that has been dominated by a handful of technologies for several years, this has led users to look for new technologies which better suit such jobs. The demand now is for low power, high memory, and I/O-intensive solutions, so there is a growing niche which can be addressed by solutions which are less focused on Flops performance.”
In this video from ISC 2015, Dan Olds from Gabriel Consulting interviews Team Spain, the first team ever to use ARM processors in the Student Cluster Competition.
“By introducing Cavium’s 64-bit ARMv8 CPUs in our Penguin Tundra family of Open Compute servers we again step up our leadership position. Our customers get outstanding value from the efficiency and flexibility enabled by OCP infrastructure combined with workload-optimized performance of Cavium’s ThunderX architecture.”
“With this delivery, the DEEP consortium can leverage a supercomputer with a peak performance of 505 TFlop/s and an efficiency of over 3 GFlop/s per Watt. The Eurotech hot water cooling solution allows for additional permanent gains in energy efficiency at data centre level as it guarantees year-round free cooling in all climate zones. The system includes a matching innovative software stack, and six carefully selected grand challenge simulation applications have been optimized to show the full performance potential of the system.”
In this video from ISC 2015, Michele De Lorenzi sits down with Rich Brueckner from insideHPC to discuss the latest updates from the conference and how the CSCS booth is constructed to reflect Switzerland’s focus on sustainability.
“Power savings, increased rack density and high performance are the three key advantages of using liquid cooling. CoolIT Systems offers options for data centers with or without facility water hook up. Any server in any rack can be liquid cooled with CoolIT’s hardware, and benefit from immediate and measurable CAPEX and OPEX savings.”
