YAIM cluster configuration: phase 1

This wiki page describes the steps needed to test the new yaim cluster module that contains the configuration of the Glue cluster and Glue subcluster entities.

The relevant yaim modules that are needed to test the new cluster configuration are:

  • yaim lcg ce: this module has been modified to include new variables and to remove the code that configures the Glue cluster and Glue subcluster entities. A branch has been created in CVS glite-yaim-lcg-ce_branch_cluster_configuration to include these changes.
  • yaim cluster: this is a new module that contains the configuration of the Glue cluster and Glue subcluster entities.
  • yaim torque server: it hasn't been changed. This implies that some new and old variables will have to coexist for some time.
  • yaim torque utils: it hasn't been changed but it's not affected by the new cluster configuration.

Installation instructions

In order to test the new cluster configuration, you can install the following metapackages:

lcg-CE
glite-TORQUE_server
glite-TORQUE_utils

Optionally, you can also install a glite-BDII, if you want to run a site BDII.

Then you should upgrade the glite-yaim-lcg-ce rpm by running:

rpm -U /afs/cern.ch/project/gd/www/yaim/testing/glite-yaim-lcg-ce-4.0.5-1.noarch.rpm

And install the new cluster configuration yaim module by running:

rpm -i /afs/cern.ch/project/gd/www/yaim/testing/glite-yaim-cluster-1.0.0-1.noarch.rpm

Configuration instructions

Since there's a set of new variables, you would need to change your usual site-info.def:

lcg CE

Mandatory variables for the lcg CE: You'll find them under /opt/glite/yaim/examples/services/lcg-ce:

The new variable names follow this syntax:

  • In general, variables based on hostnames, queues or VOViews containing '.' and '_' # should be transformed into '-'
  • <host-name>: identifier that corresponds to the CE hostname in lower case. Example: ctb-generic-1.cern.ch -> ctb_generic_1_cern_ch
  • <queue-name>: identifier that corresponds to the queue in upper case. Example: dteam -> DTEAM
  • <voview-name>: identifier that corresponds to the VOView id in upper case. '/' and '=' should also be transformed into '_'. Example: /dteam/Role=admin -> DTEAM_ROLE_ADMIN

Variable Name Description Value type Version
CE_HOST_<host-name>_CLUSTER_UniqueID UniqueID of the cluster the CE belongs to string glite-yaim-lcg-ce 4.0.5-1
CE_InfoApplicationDir Prefix of the experiment software directory in a site. This variable has been renamed in the new infosys configuration. The old variable name was: VO_SW_DIR. This parameter can be defined per CE, queue, site or voview. See /opt/glite/yaim/examples/services/lcg-ce for examples. string glite-yaim-lcg-ce 4.0.5-1

The following variables will be distributed in the future in site-info.def since they affect other yaim modules. At this moment we are in a transition face to migrate to the new variable names.

Variable Name Description Value type Version
CE_HOST_<host-name>_CE_TYPE CE type: 'jobmanager' for lcg CE and 'cream' for cream CE string glite-yaim-lcg-ce 4.0.5-1
CE_HOST_<host-name>_QUEUES Space separated list of the queue names configured in the CE. This variable has been renamed in the new infosys configuration. The old variable name was: QUEUES string glite-yaim-lcg-ce 4.0.5-1
CE_HOST_<host-name>_QUEUE_<queue-name>_CE_AccessControlBaseRule Space separated list of FQANS and/or VO names which are allowed to access the queues configured in the CE. This variable has been renamed in the new infosys configuration. The old variable name was: _GROUP_ENABLE string glite-yaim-lcg-ce 4.0.5-1
CE_HOST_<host-name>_CE_InfoJobManager The name of the job manager used by the gatekeeper. This variable has been renamed in the new infosys configuration. The old variable name was: JOB_MANAGER. Please, define: lcgpbs, lcglfs, lcgsge or lcgcondor string glite-yaim-lcg-ce 4.0.5-1

Default variables for the lcg CE: You'll find them under /opt/glite/yaim/defaults/lcg-ce.pre:

It contains a list of CE_* variables with some default values. This variables can also be specified per CE-queue-voview or CE-queue, depending if we want that a certain VOVIEW has a specific value for a certain variable, or if we want that all the VOVIEWS of a queue share a specific value. For example, if I define in site-info.def:

# In the CE vtb-generic-17.cern.ch, in the queue dteam, in the VOVIEW dteam, I want that the default value StateWaitingJobs is 666666
CE_HOST_vtb_generic_17_cern_ch_QUEUE_DTEAM_VOVIEW_DTEAM_CE_StateWaitingJobs=666666

Or I can also define:

# In the CE vtb-generic-17.cern.ch, in the queue dteam, in all the supported VOVIEWS, I want that the default value StateWaitingJobs is 666666
CE_HOST_vtb_generic_17_cern_ch_QUEUE_DTEAM_CE_StateWaitingJobs=666666

If I don't define anything, the default value for the whole CE, defined in /opt/glite/yaim/defaults/lcg-ce.pre, is taken.

The variables that can be redefined per CE-queue are:

CE_VAR="
ImplementationName
ImplementationVersion
InfoGatekeeperPort
InfoLRMSType
InfoLRMSVersion
InfoJobManager
InfoApplicationDir
InfoDataDir
InfoDefaultSE
InfoTotalCPUs
StateEstimatedResponseTime
StateRunningJobs
StateStatus
StateTotalJobs
StateWaitingJobs
StateWorstResponseTime
StateFreeJobSlots
StateFreeCPUs
PolicyMaxCPUTime
PolicyMaxObtainableCPUTime
PolicyMaxRunningJobs
PolicyMaxWaitingJobs
PolicyMaxTotalJobs
PolicyMaxWallClockTime
PolicyMaxObtainableWallClockTime
PolicyPriority
PolicyAssignedJobSlots
PolicyMaxSlotsPerJob
PolicyPreemption"

The variables that moreover can also be redefined per CE-queue-VOVIEW are:

VOVIEW_VAR="
StateRunningJobs
StateWaitingJobs
StateTotalJobs
StateFreeJobSlots
StateEstimatedResponseTime
StateWorstResponseTime
InfoDefaultSE
InfoApplicationDir
InfoDataDir
"

If the Glue schema supports other variables than the ones defined here, you can just add new ones, by redefining CE_VAR and/or VOVIEW_VAR in site-info.def. It's the list of variables contained in CE_VAR and VOVIEW_VAR what YAIM uses to create the ldif file.

Cluster

Mandatory variables for the cluster: You'll find them under /opt/glite/yaim/examples/services/glite-cluster:

The new variable names follow this syntax:

  • In general, variables based on hostnames, queues or VOViews containing '.' and '_' # should be transformed into '-'
  • <host-name>: identifier that corresponds to the CE hostname in lower case. Example: ctb-generic-1.cern.ch -> ctb_generic_1_cern_ch
  • <cluster-name>: identifier that corresponds to the cluster name in upper case. Example: my_cluster -> MY_CLUSTER
  • <subcluster-name>: identifier that corresponds to the subcluster name in upper case. Example: my_subcluster -> MY_SUBCLUSTER
