  text: In the context of high-performance computing (HPC) for distributed workloads,
    individual field-programmable gate arrays (FPGAs) need efficient ways to exchange
    data, which requires network infrastructure and software abstractions. Dedicated
    multi-FPGA clusters provide inter-FPGA networks for direct device to device communication.
    The oneAPI high-level synthesis toolchain offers I/O pipes to allow user kernels
    to interact with the networking ports of the FPGA board. In this work, we evaluate
    using oneAPI I/O pipes for direct FPGA-to-FPGA communication by scaling a SYCL
    implementation of a Jacobi solver on up to 25 FPGAs in the Noctua 2 cluster. We
    see good results in weak and strong scaling experiments.
