qhost  [  -F [resource_name,...]  ] [ -help ] [ -h host_list ] [ -j ] [
       -l resource=val,...  ] [ -ncb ] [ -u user,...  ] [ -xml ].

       qhost shows the current status  of  the  available  Univa  Grid  Engine
       hosts,  queues  and  the  jobs  associated  with  the queues. Selection
       options allow you to get information about specific hosts, queues, jobs
       or  users.  If multiple selections are done a host is only displayed if
       all selection criteria for a host are met.  Without any  options  qhost
       will display a list of all hosts without queue or job information.

       -F [ resource_name,... ]
              qhost  will  present  a detailed listing of the current resource
              availability per host with respect  to  all  resources  (if  the
              option  argument  is omitted) or with respect to those resources
              contained  in  the  resource_name  list.  Please  refer  to  the
              description  of  the Full Format in section OUTPUT FORMATS below
              for further detail.

       -help  Prints a listing of all options.

       -h host_list
              Prints a list of all hosts contained in host_list.

       -j     Prints all jobs running on the queues hosted by the shown hosts.
              This switch calls -q implicitly.

       -l resource[=value],...
              Defines the resources to be granted by the hosts which should be
              included in the host list output. Matching is performed on hosts
              based  on  non-mutable  resource  availability information only.
              That means load values are always ignored except  the  so-called
              static   load  values  (i.e.  "arch",  "num_proc",  "mem_total",
              "swap_total" and "virtual_total") ones. Also consumable utiliza-
              tion  is  ignored.   If  there are multiple -l resource requests
              they will be concatenated by a logical  AND:  a  host  needs  to
              match all resources to be displayed.

       -ncb   This  command line switch can be used in order to get 6.2u5 com-
              patible output with other qhost(1)  command  line  switches.  In
              that  case the output of the corresponding command will suppress
              information concerning the execution host  topology.  Note  that
              this option will be removed in the next major version.

       -q     Show  information  about the queues instances hosted by the dis-
              played hosts.

       -u user,...
              Display information only on those jobs and queues being  associ-

       For each host one line is printed. The output consists of consisting of

       o  the Hostname

       o  the Architecture.

       o  the  Number of processors.

       o  the Load.

       o  the Total Memory.

       o  the Used Memory.

       o  the Total Swapspace.

       o  the Used Swapspace.

       If the -q option is supplied, each host status line also contains extra
       lines for every queue hosted by the host consisting of,

       o  the queue name.

       o  the  queue  type  -  one of B(atch), I(nteractive), C(heckpointing),
          P(arallel) or combinations thereof,

       o  the number of reserved, used and available job slots,

       o  the state of the queue -  one  of  u(nknown)  if  the  corresponding
          sge_execd(8)  cannot  be contacted, a(larm), A(larm), C(alendar sus-
          pended), s(uspended), S(ubordinate), d(isabled), D(isabled), E(rror)
          or combinations thereof.

       If the state is a(alarm) at least one of the load thresholds defined in
       the load_thresholds list of the queue configuration (see queue_conf(5))
       is  currently  exceeded, which prevents from scheduling further jobs to
       that queue.

       As opposed to this, the state A(larm) indicates that at  least  one  of
       the  suspend  thresholds  of the queue (see queue_conf(5)) is currently
       exceeded. This will result in jobs running in that queue being  succes-
       sively suspended until no threshold is violated.

       The  states  s(uspended)  and  d(isabled) can be assigned to queues and
       released via the qmod(1) command. Suspending a  queue  will  cause  all
       jobs executing in that queue to be suspended.

       The  states D(isabled) and C(alendar suspended) indicate that the queue
       has been disabled or suspended automatically via the calendar  facility
       of  Univa  Grid  Engine (see calendar_conf(5)), while the S(ubordinate)
       state indicates, that the queue has been suspend via  subordination  to
       another  queue (see queue_conf(5) for details). When suspending a queue
       o  a one letter  specifier  indicating  whether  the  current  resource
          availability value was dominated by either
          `g' - a cluster global,
          `h' - a host total or

       o  a  second one letter specifier indicating the source for the current
          resource availability value, being one of
          `l' - a load value reported for the resource,
          `L' - a load value for the resource after administrator defined load
          scaling has been applied,
          `c'  -  availability  derived from the consumable resources facility
          (see complexes(5)),
          `f' - a fixed availability definition derived from a  non-consumable
          complex attribute or a fixed resource limit.

       o  after  a colon the name of the resource on which information is dis-

       o  after an equal sign the current resource availability value.

       The displayed availability values  and  the  sources  from  which  they
       derive  are  always  the  minimum  values of all possible combinations.
       Hence, for example, a line of the form "qf:h_vmem=4G" indicates that  a
       queue currently has a maximum availability in virtual memory of 4 Giga-
       byte, where this value is a fixed value (e.g. a resource limit  in  the
       queue  configuration) and it is queue dominated, i.e. the host in total
       may have more virtual memory available than this, but the queue doesn't
       allow for more. Contrarily a line "hl:h_vmem=4G" would also indicate an
       upper bound of 4 Gigabyte virtual memory availability,  but  the  limit
       would  be derived from a load value currently reported for the host. So
       while the queue  might  allow  for  jobs  with  higher  virtual  memory
       requirements, the host on which this particular queue resides currently
       only has 4 Gigabyte available.

       After the queue status line (in case of -j) a single  line  is  printed
       for each job running currently in this queue. Each job status line con-

       o  the job ID,

       o  the job name,

       o  the job owner name,

       o  the  status  of  the  job  -  one   of   t(ransfering),   r(unning),
          R(estarted),   s(uspended),  S(uspended)  or  T(hreshold)  (see  the
          Reduced Format section for detailed information),

       o  the start date and time and the function of the job (MASTER or SLAVE
          - only meaningful in case of a parallel job) and

       o  the priority of the jobs.

                      If set, specifies that debug information should be writ-
                      ten to stderr. In addition the level of detail in  which
                      debug information is generated is defined.

                      If  set,  specifies the tcp port on which sge_qmaster(8)
                      is expected to listen for communication requests.   Most
                      installations will use a services map entry for the ser-
                      vice "sge_qmaster" instead to define that port.
