Video: Neuromorphic Computing – Extreme Approaches to Weak and Strong Scaling
"Computer simulations of complex systems provide an opportunity to study their time evolution under user control. Simulations of neural circuits are an established tool in computational neuroscience. Through systematic simplification on spatial and temporal scales they provide important insights in the time evolution of networks which in turn leads to an improved understanding of brain functions like learning, memory or behavior. Simulations of large networks are exploiting the concept of weak scaling where the massively parallel biological network structure is naturally mapped on computers with very large numbers of compute nodes. However, this approach is suffering from fundamental limitations. The power consumption is approaching prohibitive levels and, more seriously, the bridging of time-scales from millisecond to years, present in the neurobiology of plasticity, learning and development is inaccessible to classical computers. In the keynote I will argue that these limitations can be overcome by extreme approaches to weak and strong scaling based on brain-inspired computing architectures."The post Video: Neuromorphic Computing – Extreme Approaches to Weak and Strong Scaling appeared first on insideHPC.

Open-source vs. Proprietary – Keeping Ideology Out of the Equation
"One of the most recurrent themes is that of open-source vs. proprietary code. This debate is often painted with the idealistic open-source evangelists on one side, and the business-focused proprietary software advocates on the other. This is, of course, an unfair depiction of the topic. In reality, when debating open-source vs. proprietary, several issues tend to get conflated into one argument – open-source vs. closed-source, free vs. paid-for, restrictive vs flexible licensing, supported vs. unsupported, code quality, and so on."The post Open-source vs. Proprietary – Keeping Ideology Out of the Equation appeared first on insideHPC.

Satoshi Matsuoka Presents: The Inevitable End of Moore’s Law
"The promising new parameter in place of the transistor count is the perceived increase in the capacity and bandwidth of storage, driven by device, architectural, as well as packaging innovations: DRAM-alternative Non-Volatile Memory (NVM) devices, 3-D memory and logic stacking evolving from VIAs to direct silicone stacking, as well as next-generation terabit optics and networks. The overall effect of this is that, the trend to increase the computational intensity as advocated today will no longer result in performance increase, but rather, exploiting the memory and bandwidth capacities will instead be the right methodology."The post Satoshi Matsuoka Presents: The Inevitable End of Moore’s Law appeared first on insideHPC.
