mlisten — display multicast pings from the ParaStation MPI daemon psid(8)
mlisten [-dv?] [-m MCAST] [-p PORT] [-n IP] [-# NODES] [--usage]
Display the multicast pings the ParaStation MPI daemon psid(8) is emitting continuously. These pings are displayed by spinning bars.
Each ping received from node N lets the Nth bar spin around one more step. For each node never received a multicast ping from a '.' is displayed.
ParaStation MPI by default no longer uses multicast messages. Thus, no multicast messages will be ever received and displayed using the default configuration!
-d
, --debug
Activate the debugging mode. This will disable the spinning bars. Instead a detailed message about each received multicast ping is displayed.
-m
, --mcast=MCAST
Listen to multicast group MCAST. Set
this to the value of MCastGroup in the ParaStation MPI
configuration file parastation.conf(5). The default
is 237, which is also the default within psid(8).
-p
, --port=PORT
Listen to UDP port PORT. Set this
to the value of MCastPort in the ParaStation MPI
configuration file parastation.conf(5). The default
is 1889, which is also the default within psid(8).
-n
, --network=IP
Listen on the network interface with address
IP. The default is to listen on any
interface. IP is the IP address of the
network interface in dot notation.
-#
, --nodes=NODES
Display information for
NODES nodes. The default is 128,
i.e. 128 nodes.
-v
, --version
Output version information and exit.
