sge_qmaster(8) - Linux man page
Name
sge_qmaster - Grid Engine master control daemon
Synopsis
sge_qmaster [ -help ]
Description
sge_qmaster controls the overall Grid Engine behavior in a cluster. For the purpose of scheduling jobs sge_qmaster cooperates with sge_schedd(8).
Options
- -help
Prints a listing of all options.
Environmental Variables
- SGE_ROOT
Specifies the location of the Grid Engine standard configuration files.
SGE_CELL
If set, specifies the default Grid Engine cell. To address a Grid Engine cell sge_qmaster uses (in the order of precedence):
The name of the cell specified in the environment variable SGE_CELL, if it is set.
The name of the default cell, i.e. default.
- SGE_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.
- SGE_QMASTER_PORT
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 service "sge_qmaster" instead to define that port.
- SGE_EXECD_PORT
If set, specifies the tcp port on which sge_execd(8) 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.
Restrictions
sge_qmaster is usually started by root on the master or shadow master machines of the cluster (refer to the Grid Engine Installation and Administration Guide for more information about the configuration of shadow master hosts). 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.
