Also provided by 1 other package version
Usage of /usr/bin/mpi-operator:
  -add_dir_header
    	If true, adds the file directory to the header of the log messages
  -alsologtostderr
    	log to standard error as well as files (no effect when -logtostderr=true)
  -alsologtostderrthreshold value
    	logs at or above this threshold go to stderr when -alsologtostderr=true (no effect when -logtostderr=true)
  -cluster-domain string

    				The cluster domain is used to construct MPI HostFile. When this is specified, the HostFile is built with "<pod-name>.<mpi-job-name>.<namespace>.svc.<cluster-domain>".
    				Otherwise, that is built with <pod-name>.<mpi-job-name>.<namespace>.svc
  -controller-queue-burst int
    	Maximum burst of the controller events queue. (default 100)
  -controller-queue-rate-limit int
    	Rate limit of the controller events queue . (default 10)
  -gang-scheduling string
    	Set gang scheduler name if enable gang scheduling. Now Supporting volcano and scheduler-plugins.
    	                Note: If you set another scheduler name, the mpi-operator assumes it's the scheduler-plugins
  -kube-api-burst int
    	Maximum burst for throttle. (default 10)
  -kube-api-qps int
    	QPS indicates the maximum QPS to the master from this client. (default 5)
  -kubeConfig string
    	Path to a kubeConfig. Only required if out-of-cluster.
  -legacy_stderr_threshold_behavior
    	If true, stderrthreshold is ignored when logtostderr=true (legacy behavior). If false, stderrthreshold is honored even when logtostderr=true (default true)
  -lock-namespace string
    	Set locked namespace name while enabling leader election. (default "mpi-operator")
  -log_backtrace_at value
    	when logging hits line file:N, emit a stack trace
  -log_dir string
    	If non-empty, write log files in this directory (no effect when -logtostderr=true)
  -log_file string
    	If non-empty, use this log file (no effect when -logtostderr=true)
  -log_file_max_size uint
    	Defines the maximum size a log file can grow to (no effect when -logtostderr=true). Unit is megabytes. If the value is 0, the maximum file size is unlimited. (default 1800)
  -logtostderr
    	log to standard error instead of files (default true)
  -master string
    	The url of the Kubernetes API server,
    			 will overrides any value in kubeconfig, only required if out-of-cluster.
  -monitoring-port int
    	Endpoint port for displaying monitoring metrics. It can be set to "0" to disable the metrics serving.
  -namespace string
    	The namespace to monitor mpijobs. If unset, it monitors all namespaces cluster-wide.
    	                If set, it only monitors mpijobs in the given namespace.
  -one_output
    	If true, only write logs to their native severity level (vs also writing to each lower severity level; no effect when -logtostderr=true)
  -skip_headers
    	If true, avoid header prefixes in the log messages
  -skip_log_headers
    	If true, avoid headers when opening log files (no effect when -logtostderr=true)
  -stderrthreshold value
    	logs at or above this threshold go to stderr when writing to files and stderr (no effect when -logtostderr=true or -alsologtostderr=true unless -legacy_stderr_threshold_behavior=false) (default 2)
  -threadiness int
    	How many threads to process the main logic (default 2)
  -v value
    	number for the log level verbosity
  -version
    	Show version and quit
  -vmodule value
    	comma-separated list of pattern=N settings for file-filtered logging
