NAME

boinc - The BOINC client program.

SYNOPSIS

boinc [options]

DESCRIPTION

The BOINC "client", boinc, is the heart of BOINC. It controls which project applications are run on your computer, downloading "Tasks" and uploading the resulting files from completed tasks. 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, boincmgr(1), or a comman-line tool called boinccmd(1), by means of Remote Procedure Calls (RPCs) over port 31416.

The BOINC client can be controlled by comman-line options, configuration files, and environment variables. Standard usage is simply to start the client running in the background.

OPTIONS

These comman-line options for boinc can be used to control how BOINC is started. Once the client has started, you should use a separate program, (boincmgr(1) or boinccmd(1)) which communicates with it by means of Remote Procedure Calls (RPCs).

GENERAL OPTIONS

--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.

PROJECT OPTIONS

--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

COMMUNICATION OPTIONS

--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 (boincmgr etc.) or the console command tool (boinccmd).

DEBUGGING OPTIONS

--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).

ACCESS CONTROL FOR GUI RPC

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.
