The NA62 experiment at CERN SPS is aimed at measuring the branching ratio of the the very rare kaon decay Kpnn. NaNet is the reconfigurable design of a FPGA-based PCI Express Network Interface Card with processing, RDMA and GPUDirect capabilities, supporting multiple link technologies.
NaNet has been employed to implement a real-time distributed processing pipeline in the the low level trigger of the experiment, operating on the data streams produced by the RICH detector with an orchestrated combination of heterogeneous computing devices (CPUs, FPGAs and GPUs).
Recent results collected during NA62 runs are presented and discussed.
