“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.”
