Bestnode

BESTNODE(M1)                       MOSIX Commands                BESTNODE(M1)
 
NAME
    BESTNODE - Select best node to run on
 
SYNOPSIS
    bestnode [-u] [-n] [-G] [-w] [-m{mb}]
  
DESCRIPTION
    Bestnode selects the best node to run a new job.
  
    Bestnode normally prints the selected node's IP address.  If the -u argu-
    ment is used and the node has an associated MOSIX node number, bestnode
    prints its MOSIX node number instead.
  
    The selection is normally for the immediate sending of a job to the
    selected node by means other than mosrun(1) (such as "rsh", "ssh", or
    MPI).  MOSIX is updated to assume that a new process will soon start on
    the selected node: when calling bestnode for any other purpose (such as
    information gathering), use the -n argument, to prevent misleading MOSIX
    that a new process is about to be started.
  
    The -G argument widens the node selection to the whole multi-cluster grid
    - otherwise, only nodes within the local cluster are chosen (the local 
    partition, if the cluster is partitioned).
    
    The -m{mb} argument narrows the selection to nodes that have at least mb
    Megabytes of free memory.
  
    When the -w argument is used, bestnode waits until an appropriate node is
    found: otherwise, if no appropriate node is found, bestnode prints "0"
    and exits.
