        <description>Modern computers are collections of heterogenous components, including GPUs, TPUs, NPUs, FPGAs and other devices that carry out computing tasks but which are not the central CPU. We are proposing novel methods of program compilation, transformation and scheduling that take advantage of the entire system so that computation takes place in the most appropriate place at the most propitious time. Using LLVM IR, optimizers, and a performance aware scheduler, we can maximize utilization while reducing execution times for arbitrary workloads, freeing developers from treating modern computers as if they were fixed function platforms. This research has applications in high performance computing, embedded systems and security due to the centrality of run time program transformation in our system. We present our results thus far from work on FreeBSD CURRENT, including updates to both the performance monitoring system (hwpmc) and a new scheduler based on performance counters.</description>
