xxqs_name_sxx_qmaster – xxQS_NAMExx master control daemon

Synopsis

xxqs_name_sxx_qmaster [ -help ]

Description

xxqs_name_sxx_qmaster controls the overall xxQS_NAMExx behavior in a cluster.

Options

-help

Prints a listing of all options.

Environment Variables

xxQS_NAME_Sxx_ROOT

Specifies the location of the xxQS_NAMExx standard configuration files.

xxQS_NAME_Sxx_CELL

If set, specifies the default xxQS_NAMExx cell. To address a xxQS_NAMExx cell xxqs_name_sxx_qmaster uses (in order of precedence):

The name of the cell specified in the environment variable xxQS_NAME_Sxx_CELL, if it is set.

The name of the default cell, i.e. default.

xxQS_NAME_Sxx_DEBUG_LEVEL

If set, specifies that debug information should be written to stderr. In addition, the level of detail in which debug information is generated is defined by the defined value.

xxQS_NAME_Sxx_DEBUG_LEVEL

If set, the qmaster will not daemonize.

xxQS_NAME_Sxx_QMASTER_PORT

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

xxQS_NAME_Sxx_EXECD_PORT

If set, specifies the tcp port on which is expected to listen for communication requests. Most installations will use a services map entry for the service "sge_execd" instead to define that port.

xxQS_NAME_Sxx_TEST_DELAY_SCHEDULING

If set, specifies a delay in (integral seconds) before a scheduling run, for test purposes.

SGE_ND

If set, don’t daemonize the program (for debugging).

SGE_ENABLE_COREDUMP

If set, enable core dumps on Linux when the admin_user is not root. Linux normally disables core dumps when the daemon has changed uid or gid. Setting SGE_ENABLE_COREDUMP in xxqs_name_sxx_qmaster’s environment defeats that to enable core dumps for debugging if they are otherwise allowed. This is typically not a big hazard with xxQS_NAME_Sxx, since most information is exposed in the spool area anyhow. Dumps will appear in the host spool directory.
On Solaris, may be used to enable such dumps.

SGE_QMASTER_PIDFILE

Path name of file to which to write the daemon process id at startup (default "qmaster.pid"). Note that this must be writable by the admin user (see

Restrictions

xxqs_name_sxx_qmaster is usually started from root on the master or shadow master machines of the cluster. If started by a normal user, a master spool directory must be used to which the user has read/write access. In this case only jobs being submitted by that same user are handled correctly by the system.
