boinc - The BOINC client program.

       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.

       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.

       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).

   GENERALOPTIONS--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.

       --dirpath
              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_delayX
              Delay starting apps for X secs.

   PROJECTOPTIONS--attach_projectURLkey
              Attach to a project using URL and authenticator.

       --show_projects
              Show attached projects.

       --detach_projectURL
              Detach from project specified by URL.

       --reset_projectURL
              Reset (clear) the projectspecified by URL.

       --update_prefsURL
              Contact the project specified by URL to update preferences

   COMMUNICATIONOPTIONS--allow_remote_gui_rpc
              Allow RPC connections from remote hosts.

       --gui_rpc_portport
              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).

   DEBUGGINGOPTIONS--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_startN
              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_periodN
              Give up on file transfers after N sec.

       --master_fetch_intervalN
              Limiting the period of project master file dowload retries.

       --master_fetch_periodN
              Reload a project's master file after N RPC failures.

       --master_fetch_retry_capN
              Exponential backoff limit for downloading project master files.

       --no_priority_change
              Run applications at same priority as client.

       --pers_giveupN
              Giveup time for persistent file transfer errors.

       --pers_retry_delay_maxN
              Maximum time (sec) for file transfer exponential backoff.

       --pers_retry_delay_minN
              Minimum time (sec) for file transfer exponential backoff.

       --redirectio
              Redirect stdout and stderr to log files (stdoutdae.txt and stderrdae.txt).

       --retry_capN
              Limit the maximum exponential backoff time.

       --sched_retry_delay_maxN
              Maximum time (sec) for project RPC exponential backoff.

       --sched_retry_delay_minN
              Minimum time (sec) for project RPC exponential backoff.

       --unsigned_apps_ok
              Allow unsigned apps (for testing).
