Retrieve status information for the specified compute profile, comprising current connections and daemons status.
status(.compute = "default")[default 'default'] character compute profile (each compute profile has its own set of daemons for connecting to different resources).
or a 'miraiCluster' to obtain its status.
A named list comprising:
connections - integer number of active connections.
Using dispatcher: Always 1L as there is a single connection to
dispatcher, which connects to the daemons in turn.
daemons - of variable type.
Using dispatcher: a status matrix (see Status Matrix section below),
or else an integer 'errorValue' if communication with dispatcher failed.
Not using dispatcher: the character host URL.
Not set: 0L.
When using dispatcher, $daemons comprises an integer matrix with
the following columns:
i - integer index number.
online - shows as 1 when there is an active connection, or else 0 if a daemon has yet to connect or has disconnected.
instance - increments by 1 every time there is a new
connection at a URL. This counter is designed to track new daemon
instances connecting after previous ones have ended (due to time-outs
etc.). The count becomes negative immediately after a URL is regenerated
by saisei, but increments again once a new daemon connects.
assigned - shows the cumulative number of tasks assigned to the daemon.
complete - shows the cumulative number of tasks completed by the daemon.
The dispatcher URLs are stored as row names to the matrix.
