+Building Tool Chains for RISC-V AI Accelerators - Jeremy Bennett, Embecosm
+
+Our client is developing a massively parallel 64-bit chip for AI inference workloads.
+To facilitate early software development, we are bringing up an AI tool flow for this
+chip in a QEMU RISC-V environment. In this talk, we'll share our experience of getting
+three key AI frameworks working with RISC-V QEMU: Pytorch, Tensorflow and the OpenXLA
+compiler. Our talk will share our experience addressing two key issues. We will describe
+the challenges we faced, their solutions and reflect on the lessons learned for future work.
+The first of these is simply getting the tools to effectively run in an emulated
+RISC-V environment. These tools are large, fast moving pieces of software with extensive
+external dependencies. Our second challenge is performance. AI workloads are inherently
+parallel, and hence run efficiently on vector enabled hardware. However RISC-V vector (RVV)
+is relatively new, and we experienced difficulty getting the performance we expected
+out of the tool flow. At the end of this talk, we hope our audience will have a better
+understanding of the challenges in bringing up an AI tool flow under QEMU. We hope our
+experience will help them bring up their own AI tool flows.
