It controls which project applications are run on your computer, downloading "Tasks" and uploading the resulting files from completed tasks. &cmd_boinc; is usually run in the background, ideally as a daemon. It can then be controlled either by a graphical tool called the BOINC Manager, &man_boincmgr;, or a command-line tool called &man_boinccmd;, by means of Remote Procedure Calls (RPCs) over port &rpc_port;. The BOINC client can be controlled by command-line options, configuration files, and environment variables. Standard usage is simply to start the client running in the background. These command-line options for &cmd_boinc; can be used to control how BOINC is started. Once the client has started, you should use a separate program, (&man_boincmgr; or &man_boinccmd;) which communicates with it by means of Remote Procedure Calls (RPCs). --help Show options. --version Show version info. --run_cpu_benchmarks Run the CPU benchmarks. --check_all_logins For idle detection, check remote logins too. --daemon Run as daemon. Will redirect stderr and stdout to syslog. --dir path Use given dir as the client working directory. --no_gpus Don't check for GPUs. --no_info_fetch Don't fetch project list or client version info from boinc.berkeley.edu. --skip_cpu_benchmarks Don't run CPU benchmarks. --start_delay X Delay starting apps for X secs. --attach_project URL key Attach to a project using URL and authenticator. --show_projects Show attached projects. --detach_project URL Detach from project specified by URL. --reset_project URL Reset (clear) the projectspecified by URL. --update_prefs URL Contact the project specified by URL to update preferences --allow_remote_gui_rpc Allow RPC connections from remote hosts. --gui_rpc_port port Port for RPCs. --no_gui_rpc Omits creation of a socket as required for the remote control of the client. Consequently the client cannot be controlled by external tools like GUIs (&cmd_boincmgr; etc.) or the console command tool (&cmd_boinccmd;). --abort_jobs_on_exit When client exits, abort and report tasks. --allow_multiple_clients Allow more than one client instance per host. --exit_after_app_start N Exit N seconds after an app starts. Useful to look at the files in the slot directory. --exit_after_finish Exit right after finishing a task. Useful to look at the files in the slot directory. --exit_before_start Exit right before starting a task. Useful to look at the files in the slot directory. --exit_before_upload Exit right before starting an upload. --exit_when_idle Exit when there are no more tasks to work on. --fetch_minimal_work Fetch only 1 task per device. --file_xfer_giveup_period N Give up on file transfers after N sec. --master_fetch_interval N Limiting the period of project master file dowload retries. --master_fetch_period N Reload a project's master file after N RPC failures. --master_fetch_retry_cap N Exponential backoff limit for downloading project master files. --no_priority_change Run applications at same priority as client. --pers_giveup N Giveup time for persistent file transfer errors. --pers_retry_delay_max N Maximum time (sec) for file transfer exponential backoff. --pers_retry_delay_min N Minimum time (sec) for file transfer exponential backoff. --redirectio Redirect stdout and stderr to log files (stdoutdae.txt and stderrdae.txt). --retry_cap N Limit the maximum exponential backoff time. --sched_retry_delay_max N Maximum time (sec) for project RPC exponential backoff. --sched_retry_delay_min N Minimum time (sec) for project RPC exponential backoff. --unsigned_apps_ok Allow unsigned apps (for testing). By default the client accepts GUI RPC connections only from programs on the same host, which means that any user on this host can control the client. &man_boinccmd;, &man_boincmgr; Copyright © 2007-2020 University of California.
