Adding a Site to a Glidein Factory

Contents

These instructions assume you know the gatekeeper hostname and the VO who requested the entry. The instructions deviate depending on if it is a site that supports CMS or not. The extra steps needed for adding CMS sites will be marked accordingly.

Find Site in BDII

Check OSG BDII (is.grid.iu.edu) first:

$> lds osg hostname* | less

If it isn't there try CERN BDII (exp-bdii.cern.ch):

$> lds egi hostname* | less

Find a queue that supports the VO and has reasonable wallclock limits. Look for the lower of GlueCEPolicyMaxCPUTime and GlueCEPolicyMaxWallClockTime and ensure it has enough time.

GlueCEAccessControlBaseRule: VO:VO
GlueCEPolicyMaxWallClockTime: MINUTES
GlueCEPolicyMaxCPUTime: MINUTES

Make note of the GlueCEUniqueID:

GlueCEUniqueID=hostname:port/jobmanager-jm_type-queue

Find site in SiteDB (CMS only)

If it is a CMS site you need to collect some info not guaranteed to be in BDII, and not guaranteed to be accurate if it is. We store a local copy of SiteDB on glidein-1 at:

/home/gfactory/cms_sitedb/sitedb.xml

Search for the hostname and note the site name as well as the SE. The site name as seen in SiteDB from here on out will be known as cmssite_name

Required Fields

We have a tool that extracts most fields for you from BDII. However there are a few that need to be manually supplied. These are:

• entry_name
• site_name - shortend group name to logically group different entries to same site. Usually just use a common portion of the entry_name
• supported_vos - comma separated GLIDEIN_Supported_VOs list
• cmssite_name (CMS only) - see SiteDB section above.
• SE (CMS only) - see SiteDB section above

entry_name Conventions

We use the following conventions to name an entry in the factory:

• If CMS site, append CMS_ in front of the cmssite_name
• If not CMS site, start with VO name followed by country code followed by a name to describe the site.
• For both CMS and non-CMS end the name with something to distinguish the gatekeeper or queue for that particular entry.

CMS example: CMS_T2_US_UCSD_gw2
Non-CMS example: OSG_BR_UNESP_medium

Run add_new_entry

add_new_entry takes different arguments depending on the type of site and whether or not it supports CMS.

• If it supports CMS, run:

$> add_new_entry -p cms_plugin.py glideinWMS.xml glideinWMS.xml.test bdii_server GlueCEUniqueID=GlueCEUniqueID entry_name site_name supported_vos "Added date --your_name" cmssite_name SE

• Otherwise if it is a site that does not support CMS, run:

$> add_new_entry glideinWMS.xml glideinWMS.xml.test bdii_server GlueCEUniqueID=GlueCEUniqueID entry_name site_name supported_vos "Added date --your_name"
