PNNL Looks at Undervolting to Meet Exascale Goals

Figure depicting the general constraints at scale for building exascale architectures. The undervolting component (shown in 4) is part of ongoing work that PNNL’s HPC group and their collaborators are conducting in the effort to build highly resilient and energy-efficient HPC systems.

PNNL researchers are using supercomputers to take on two of the main challenges of exascale: energy efficiency and resiliency. Their simulations show that dynamic voltage scaling, also known as undervolting, can reduce power consumption and leverage existing mainstream resilience techniques at scale for improving system failure rates.

Alternatives to x86: Future Processing Technologies

Robert Roe

In the second article in his series on future hardware for HPC, Robert Roe from Scientific Computing World looks at alternatives to the x86, including server on a chip and OpenPower.

E4-ARKA: ARM64+GPU+IB is Now Here

e4

“E4 Computer Engineering has introduced ARKA, the first server solution based on ARM 64 bit SoC dedicated to HPC. The compute node is boosted by discrete GPU NVIDIA cards K20 with 10Gb ethernet and FDR InfiniBand networks implemented by default. In this presentation, the hardware configuration of the compute node is described in detail. The unique capabilities of the ARM+GPU+IB combination are described, including many synthetic benchmarks and application tests with particular attention to molecular dynamics software.”
