       boinc - The BOINC client program.


       boinc [options]


       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

       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


       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).

       --help Show options.

              Show version info.

              Run the CPU benchmarks.

              For idle detection, check remote logins too.

              Run as daemon. Will redirect stderr and stdout to syslog.

       --dir path
              Use given dir as the client working directory.

              Don't check for GPUs.

              Don't fetch project list or client version info from

              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 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 RPC connections from remote hosts.

       --gui_rpc_port port
              Port for RPCs.

              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).

              When client exits, abort and report tasks.

              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

              Exit  right  after  finishing  a  task.  Useful  to  look  at the files in the slot

              Exit right before starting a task.  Useful  to  look  at  the  files  in  the  slot

              Exit right before starting an upload.

              Exit when there are no more tasks to work on.

              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.

              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.

              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.

              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.
