They are summarized and briefly described in the Nanos6 default configuration file as well as in the `OmpSs-2 user guide `_, the FPGA architecture section is shown below: .. code:: bash [devices] directory = true [devices.fpga] # Enable/disable the reverse offload service reverse_offload = false # Byte alignment of the fpga memory allocations alignment = 16 # If xtasks supports async copies, it can be "async", if not, the runtime can use the default xtasks memcpy and # simulate an asynchronous copy spawning a new thread with "forced async". Copies can also be synchronous with "sync". mem_sync_type = "sync" page_size = 0x8000 requested_fpga_memory = 0x40000000 # Enable FPGA device service threads. It is useful to disable them when using the broadcaster, because in that case the # FPGAs are handled by the broadcaster device service and the FPGA services are not used. enable_services = true # Maximum number of FPGA tasks running at the same time streams = 16 [devices.fpga.polling] # Indicate whether the FPGA services should constantly run while there are FPGA tasks # running on their FPGA. Enabling this option may reduce the latency of processing FPGA # tasks at the expenses of occupying a CPU from the system. Default is true pinned = true # The time period in microseconds between FPGA service runs. During that time, the CPUs # occupied by the services are available to execute ready tasks. Setting this option to 0 # makes the services to constantly run. Default is 1000 period_us = 1000
