SGE Cluster Configuration
Using qconf Command
To view the basic cluster and host configuration use the qconf -sconf command:
qconf -sconf [global] qconf -sconf host_name
Example:
qconf -sconf
global:

qconf -shgrpl @allhosts
To modify the basic cluster or host specific configuration use the following commands:
qconf -mconf global qconf -mconf host_name

SGE Types
Some SGE command line switches and file attributes are types that are explained in man sge_types:
pattern
When ever patterns are used the following definition applies:
"*" matches any character and any number of characters
(between 0 and inv).
"?" matches any character. It cannot be no character
"." is the character ".". It has no other meaning
"\" escape character. "\\" = "\", "\*" = "*", "\?" = "?"
"[xx]" specifies an array or a range of allowed
characters for one character at a specific position
The pattern itself should be put into double quotes to ensure,
that the clients get the pattern. The or | operator is not supported.
wc_host
A wildcard host specification is a wildcard expression which might match
one or more hosts used in the cluster, e.g.:
* all hosts
That string never contains an at-character @ even if the expression begins with a wildcard character.
wc_hostgroup
A wildcard hostgroup specification, e.g.:
@* all hostgroups in the cluster
wc_queue
wc_queue := wc_cqueue | wc_qdomain | wc_qinstance
A wildcard queue expression, e.g.:
all.q
all.q@mode01
*@node01
wc_cqueue
A wildcard cluster queue specification is a wildcard expression which might
match one or more cluster queues used in the cluster, e.g.:
* all cluster queues
a* all cluster queues beginning with an a
wc_qinstance
wc_qinstance := wc_cqueue "@" wc_host
wc_qinstance expressions are used to address a group of queue instances
whose underlaying hostname matches the given pattern, e.g.:
*@* all queue instances in the cluster
*@b* all queue instances whose hostname begins with b
wc_qdomain
wc_qdomain := wc_cqueue "@" wc_hostgroup
A wildcard queue domain specification, e.g.:
*@@* all queue instances whose underlaying
host is part of at least one hostgroup
wc_queue_list
Comma separated list of wildcard queue expressions.
Tasks
Find the master hostname:
cat $SGE_ROOT/$SGE_CELL/common/act_qmaster merlinf1
Configure the cell wide default submit options:
emacs $SGE_ROOT/$SGE_CELL/common/sge_request
Files
