Description
Updated yaim lcg-ce
New version of the yaim module for the lcg CE containing configuration changes as requested in:
- The WN Working Group. See https://twiki.cern.ch/twiki/bin/view/EGEE/WNWorkingGroup (Key item B)
- The Installed Capacity Document. See https://twiki.cern.ch/twiki/pub/LCG/WLCGCommonComputingReadinessChallenges/WLCG_GlueSchemaUsage-1.8.pdf (page 13)
It also fixes a series of bugs mainly dealing with:
- Service provider configuration
- LDIF file fixes
New YAIM variables
===============
The following variables need to be defined by the sys admins (examples are distributed under site-info.def in yaim core but already required by the lcg CE configuration functions)
- CE_OTHERDESCR: This YAIM variable is used to set the GlueHostProcessorOtherDescription attribute. The value of this variable MUST be set to:
Cores=<typical number of cores per CPU> [, Benchmark=<value>-HEP-SPEC06] where <typical number of cores per CPU>
is equal to the number of cores per CPU of a typical Worker Node in a SubCluster. The second value of this attribute MUST be published only in the case the CPU
power of the SubCluster is computed using the Benchmark HEP-SPEC06.
- CE_CAPABILITY: This YAIM variable is a blank separated list and is used to set the GlueCECapability attribute. In particular, site administrators MUST
define the following values: CPUScalingReferenceSI00=<referenceCPU SI00>; the reference CPU SI00 is the internal batch scaling factor used to normalize the
GlueCEMaxCPUTime. The <referenceCPU SI00> is expressed in SI00. If internal scaling is not done this capability MUST be published and its value set to the
minimum value of the corresponding SubClusters GlueHostBenchmarkSI00. Share=<VO>:<share>; this value is used to express specific VO shares if
set. If there is no special share, this value MUST NOT be published. <VO> is the VO name and <share> can assume values between 1 and 100
(it represents a percentage). Please note that the sum of the shares over all WLCG VOs MUST BE less than or equal to 100. The syntax is
CPUScalingFactorSI00=value [Share=vo-name1:value [Share=vo-name2:value [...]]]
- SE_MOUNT_INFO_LIST: This YAIM variable is used to set the GlueCESEBindMountInfo attribute for each defined SE. The variable is a space separated list of
SE hosts from SE_LIST with the export directory from the Storage Element and the mount directory common to worker nodes part of the Computing Element like
SE1:export_dir1,mount_dir1. If any SE from SE_LIST doesn't support he mount concept, don't define anything for that SE in this variable. If this is the case for all the SEs
in SE_LIST, put the value none. The GlueCESEBindMountInfo will be in both cases "n.a".
The following are default variables that do not need to be defined, only for advanced configurations:
- CLUSTER_HOST: this variable must be set to CE_HOST for the time being. It's defined under INSTALL_ROOT/glite/yaim/defaults/lcg-ce.post.
Please also have a look at the list of known issues.
This update fixes various bugs. For the full list of bugs, please see list below.
