I try not to heavily promote Intel events, but I thought this one might interest folks here, especially ones using Nvidia drivers 
“We have a really cool guest speaker - Karol Herbst, he is the co-maintainer of nouveau, the Linux kernel open source NVidia driver, Mesa developer, and rusticle project that is working with SYCL. Lot of folks are excited about this talk as he will be talking about how things like OpenCL works in Mesa, experiments with SYCL in rustic which is the rust implementation of OpenCL.”
