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 command-line tool called boinccmd(1), by means of Remote Procedure
       Calls (RPCs) over port 31416.

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

OPTIONS

These command-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.
