Boasting a unique, advanced parallel computing architecture, and a high performance, low latency interconnect, the BrownDwarf Y-class supercomputer represents the dawn of a new era marked by eco-friendly, heterogeneous systems that define a new category of high performance computers. Achieving an unparalleled level of power efficiency when looking at total system power consumption, a 144 node configuration delivers 70 Teraflops of performance at 10kw inside a 42U high rack.
Power efficiency has become a critical driving factor in the deployment of high-end computing systems. Today, many developers have a strong interest in comparing specific algorithms to their effect on power consumption. In response to this growing need, a unique feature of the BrownDwarf system is that the power distribution system in each node is instrumented with 36 separate voltage, current and temperature measurement points. With a user controlled, nanosecond accurate triggering and clocking mechanism, high-resolution measurements are captured out-of-band and directly synchronized with algorithm results during analysis.
The BrownDwarf Y-class node leverages multiple Keystone-II and Keystone-I SoC components from Texas Instruments Incorporated (TI). Each node integrates four ARM Cortex-A15 MPCore processors, 24 TMS320C66x digital signal processor (DSP) cores and 26GB of ECC memory.
According to Ian Lintault, managing director of nCore HPC, "The BrownDwarf Y-Class system is an incredibly important milestone in HPC system development. Working in close collaboration with TI, IDT and our hardware partner Prodrive, we have successfully established a new class of energy efficient supercomputers designed to fulfill the demands of a wide range of scientific, technical and commercial applications. We are very excited to be launching the most capable energy efficient supercomputer available. The innovative design of the BrownDwarf Y-class system has resulted in a network fabric that far exceeds the latency and power efficiencies of traditional supercomputing systems based on x86 and Infiniband or Ethernet systems. By utilizing existing programming models and toolsets, the BrownDwarf Y-Class supercomputer is a disruptive force in HPC as it leapfrogs a number of the supercomputing incumbents."
nCore selected RapidIO as the compute fabric for BrownDwarf Supercomputer based on the key benefits of throughput, latency, reliability and overall system power utilization that could not be achieved with Infiniband and Ethernet-based approaches. The onboard IDT Gen 2 RapidIO switch fabric offers 20 Gbps of bandwidth per node, 100 ns cut through latency, 300mW per 10 Gbps of data and up to 2.2Tbps of non-blocking switching capability per Y-Class system chassis.
Programmable in C/C++ using OpenMP, OpenCL, and OpenMPI, the BrownDwarf system preserves the user's existing investment in mission-critical codes while reducing technical risk. An optimized version of Linux runs on the ARM side providing access to common scientific computing tools and libraries.
