Tutorial: Loihi

We’ll cover a few new “advanced” topics of interest to the community. These are

• Characterizing energy and performance of Loihi workloads
• Solving and constraint satisfaction problems on Loihi and benchmarking them to a state-of-the-art CPU solver
• Training deep SNNs for Loihi with SLAYER

We’ll present on these topics and show some code running. Anyone who has access to Loihi will be able to find and run the code themselves, but we’d like to clarify that access to Loihi is not required for attending the tutorials. (If you want to get access to Loihi, please email inrc_interest@intel.com to get legal access to the Loihi cloud systems.)

Lightning talk: Comparing Neural Accelerators & Neuromorphic Architectures The False Idol of Operations

Accompanying the advanced computing capabilities neural networks are enabling across a suite of application domains, there is a resurgence in interest in understanding what architectures can efficiently enable these advanced computational demands. Both neural accelerators and neuromorphic approaches are emerging at different scales, resource requirements, and enabling capabilities. Beyond the similarity of executing neural network workloads, these two paradigms exhibit significant differences. Accordingly, here we compare neural accelerators and neuromorphic architectures highlighting that operations alone are a lacking singular measure of performance.
