NAME

       iceccd - Icecream daemon

SYNOPSIS

       iceccd [-b env-basedir] [--cache-limit MB] [-d] [-l log-file] [-m max-processes] [-N hostname] [-n node-
              name] [--nice level] [--no-remote] [-s scheduler-host] [-u user] [-v[v[v]]]

DESCRIPTION

       The  Icecream daemon has to run on all nodes being part of the Icecream compile cluster. It receives com‐
       pile jobs and executes them in a chroot environment. The compile clients send their  compile  environment
       the  first  time  they  send a job to a particular daemon, so that the environment of the daemon does not
       have to match the one of the client.

       The daemon also has to run on clients sending compile jobs to the Icecream network. If a node  should  be
       able to send compile jobs, but never receive any, start the daemon with the option -m 0.

       All  Icecream  daemons  need to have contact to the Icecream scheduler which controls the distribution of
       data between compile nodes. Normally the daemon will automatically find the right scheduler. If  this  is
       not  the case you can explicitly specify the name of the Icecream network and the host running the sched‐
       uler.

OPTIONS

       -b, --env-basedir env-basedir
              Base directory for storing compile environments sent to the daemon by the compile clients.

       --cache-limit MB
              Maximum size in Mega Bytes of cache used to store compile environments of compile clients.

       -d, --daemonize
              Detach daemon from shell.

       -h, --help
              Print help message and exit.

       -l, --log-file log-file
              Name of file where log output is written to.

       -m, --max-processes max-processes
              Maximum number of compile jobs started in parallel on machine running the daemon.

       -N hostname
              The name of the icecream host on the network.

       -n, --name, --netname net-name
              The name of the icecream network the daemon should connect to.  There has to be a  scheduler  run‐
              ning for the network under the same network name.

       --nice level
              The level of niceness to use. Default is 5.

       --no-remote
              Prevents jobs from other nodes being scheduled on this one.

       -s, --scheduler-host scheduler-host
              Name of host running the scheduler for the network the daemon should connect to. This option might
              help  if  the  scheduler  cannot broadcast its presence to the clients due to firewall settings or
              similar reasons, when this is enabled scheduler should use --persistent-client-connection.

       -u, --user-uid user
              Specify the system user used by the daemon, which must be different than ‘root’. If not specified,
              the daemon defaults to the ‘icecc’ system user if available, or ‘nobody’ if not.

       -v, -vv, -vvv
              Control verbosity of daemon. The more v the more verbose.
