resolves openMosix-ID, ip-addresses and hostnames of the cluster
display the (openMosix-) load
shows the (openMosix-) speed
displays the current status and configuration
is a node up or down (openMosix kind of ping)
shows logical free memory
shows physical free mem
sets a new Yardstick-value
sets a new (openMosix-) speed value
sets a new decay-interval
mosrun -run a special configured command on a chosen node
mosrun [-h|openMosix_ID| list_of_openMosix_IDs] command [arguments]
The mosrun command can be executed with several more commandline options. To ease this up there are several preconfigured run-scripts for executing jobs with a special (openMosix) configuration.
Table 8-7. extra options for mosrun
runs a command which process(es) won't migrate
executes a command locked to its home node
runs a command which will be directly migrated and locked to a node
tells the openMosix cluster that this is a cpu-bound process
tells the openMosix cluster that this is a io-bound process
executes a command and tells the cluster not to refresh the load-balancing statistics
executes a command with a slow decay interval for collecting load-balancing statistics
executes a command with a fast decay interval for collecting load-balancing statistics
setpe -manual node configuration utility
setpe -w -f [hpc_map]
setpe -r [-f [hpc_map]]
-w reads the openMosix configuration from a file (typically /etc/hpc.map)
-r writes the current openMosix configuration to a file (typically /etc/hpc.map)
-off turns the current openMosix configuration off
tune openMosix calibration and optimizations utility.
(for further informations review the tune-man page)
Additional to the /proc interface and the commandline-openMosix utilities (which are using the /proc interface) there is a patched "ps" and "top" available (they are called "mps" and "mtop") which displays also the openMosix-node ID on a column. This is useful for finding out where a specific process is currently being computed.
This actually summarised the command line tools, but have a look at openMosixview which is a GUI for the most common administration tasks, and which ill be discussed in a future chapter.
