They are summarized and briefly described in the Nanos++ help, the FPGA architecture section is shown below: .. code:: bash FPGA specific options NX_ARGS options --fpga-alloc-align [=] FPGA allocation alignment (def: 16) --fpga-alloc-pool-size [=] FPGA device memory pool size (def: 512MB) --fpga-create-callback --no-fpga-create-callback Register the task creation callback during the plugin initialization (def: false - automatically enabled when needed) --fpga-create-callback-disable --no-fpga-create-callback-disable Disable the registration of the task creation callback to handle task creation from the FPGA (def: false) --fpga-disable --no-fpga-disable Disable the support for FPGA accelerators and allocator --fpga-enable --no-fpga-enable Enable the support for FPGA accelerators and allocator --fpga-finish-task-burst [=] Max number of tasks to be finalized in a burst when limit is reached (def: 8) --fpga-helper-threads [=] Defines de number of helper threads managing fpga accelerators (def: 1) --fpga-hybrid-worker --no-fpga-hybrid-worker Allow FPGA helper thread to run smp tasks (def: enabled) --fpga-idle-callback --no-fpga-idle-callback Perform fpga operations using the IDLE event callback of Event Dispatcher (def: enabled) --fpga-instrumentation-buffer-size [=] Maximum number of events to be saved from a FPGA task (def: 170) --fpga-instrumentation-callback --no-fpga-instrumentation-callback Handle the FPGA instrumentation using the IDLE event callback of Event Dispatcher (def: enabled) --fpga-max-pending-tasks [=] Number of tasks allowed to be pending finalization for an fpga accelerator (def: 4) --fpga-max-threads-callback [=] Max. number of threads concurrently working in the FPGA IDLE callback (def: 1) --fpga-num [=] Defines de number of FPGA acceleratos to use (def: #accels from libxtasks) Environment variables NX_FPGA_ALLOC_ALIGN = FPGA allocation alignment (def: 16) NX_FPGA_ALLOC_POOL_SIZE = FPGA device memory pool size (def: 512MB) NX_FPGA_DISABLE = yes/no Disable the support for FPGA accelerators and allocator NX_FPGA_ENABLE = yes/no Enable the support for FPGA accelerators and allocator NX_FPGA_FINISH_TASK_BURST = Max number of tasks to be finalized in a burst when limit is reached (def: 8) NX_FPGA_HELPER_THREADS = Defines de number of helper threads managing fpga accelerators (def: 1) NX_FPGA_HYBRID_WORKER = yes/no Allow FPGA helper thread to run smp tasks (def: enabled) NX_FPGA_INSTRUMENTATION_BUFFER_SIZE = Maximum number of events to be saved from a FPGA task (def: 170) NX_FPGA_MAX_PENDING_TASKS = Number of tasks allowed to be pending finalization for an fpga accelerator (def: 4) NX_FPGA_MAX_THREADS_CALLBACK = Max. number of threads concurrently working in the FPGA IDLE callback (def: 1) NX_FPGA_NUM = Defines de number of FPGA acceleratos to use (def: #accels from libxtasks)
