Implementation of graph neural networks on CPU + FPGA co-processors for scalable track reconstruction tasksRun 2 of the LHC on the CMS detector produced a data rate on the scale of hundreds of terabytes per second. Being able to reduce the data within a few milliseconds and sift through the data in a reasonable time frame to produce meaningful results is crucially important. Future increases in instantaneous luminosity, meaning more proton-proton collisions per bunch-crossing, will lead to data produced at increasingly larger rates, causing scalability issues in traditional particle track reconstruction algorithms. This project proposes to implement a graph network that can be evaluated on a CPU that has a FPGA co-processors. This will allow trained networks to be run online in a highly parallelized fashion, greatly accelerating data throughput.
