Description du projet :
utiliser le cluster OPI’One pour créer une Crunch’Box BOINC !
Une Crunch’Box BOINC ? C’est quoi ?
C’est un ensemble de serveur utilisé pour le projet de calcul reparti BOINC comme le célèbre SETI@home.
Les étapes d’installation
installation de boinc-client et de l’interface d’administration boinctui
pi@master:~$ sudo apt-get install boinc-client boinctui
commandes de l’interface boinccmd
pi@master:~$ boinccmd --help usage: boinccmd [--host hostname] [--passwd passwd] [--unix_domain] command default hostname: localhost default password: contents of gui_rpc_auth.cfg Commands: --client_version show client version --create_account URL email passwd name --file_transfer URL filename op file transfer operation op = retry | abort --get_cc_status --get_daily_xfer_history show network traffic history --get_disk_usage show disk usage --get_file_transfers show file transfers --get_host_info --get_message_count show largest message seqno --get_messages [ seqno ] show messages > seqno --get_notices [ seqno ] show notices > seqno --get_project_config URL --get_project_status show status of all attached projects --get_proxy_settings --get_simple_gui_info show status of projects and active tasks --get_state show entire state --get_tasks show tasks --get_old_tasks show reported tasks from last 24 hours --join_acct_mgr URL name passwd attach account manager --lookup_account URL email passwd --network_available retry deferred network communication --project URL op project operation op = reset | detach | update | suspend | resume | nomorework | allowmorework | detach_when_done | dont_detach_when_done --project_attach URL auth attach to project --quit tell client to exit --quit_acct_mgr quit current account manager --read_cc_config --read_global_prefs_override --run_benchmarks --set_gpu_mode mode duration set GPU run mode for given duration mode = always | auto | never --set_host_info product_name --set_network_mode mode duration set network mode for given duration mode = always | auto | never --set_proxy_settings --set_run_mode mode duration set run mode for given duration mode = always | auto | never --task url task_name op task operation op = suspend | resume | abort
autoriser la connection d’un client distant:
pi@master:~$ sudo nano /etc/boinc-client/cc_config.xml <!-- This is a minimal configuration file cc_config.xml of the BOINC core client. For a complete list of all available options and logging flags and their meaning see: https://boinc.berkeley.edu/wiki/client_configuration --> <cc_config> <log_flags> <task>1</task> <file_xfer>1</file_xfer> <sched_ops>1</sched_ops> </log_flags> <options> <allow_remote_gui_rpc>1</allow_remote_gui_rpc> </options> </cc_config>
configurer un mot de passe :
pi@master:~$ sudo nano /etc/boinc-client/gui_rpc_auth.cfg orangepi
indiquer les ip autorisées à se connecter :
pi@master:$ sudo nano /etc/boinc-client/remote_hosts.cfg # This file contains a list of hostnames or IP addresses (one per line) # of remote hosts, that are allowed to connect and to control the local # BOINC core client via GUI RPCs. # Lines beginning with a # or a ; are treated like comments and will be # ignored. # #host.example.com #192.168.0.180 192.168.169.1 192.168.1.47
ajouter le projet Seti a Boinc :
pi@master:~$ sudo boinccmd --project_attach http://setiathome.berkeley.edu {authenticator key}forcer la mise à jour de Boinc :
pi@master:~$ boinccmd --passwd orangepi --project setiathome.berkeley.edu/ update
