Operational issues

Report from DMSU

  • FYI: Collocated CREAM and ARGUS authorization issues. There were two similar issues where CREAM's queries to ARGUS were being refused. Quoting from the solution: The issue was caused by configuration of CREAM and Argus nodes with different group sets on the same machine. This is not supported by YAIM, special care is necessary. Since this problem cropped up at least twice in very short succession, it may be worth mentioning. No special action is necessary, though.

The issue is represented like this in the CREAM log (excerpt form the NecTec site):

26 Jan 2015 03:24:54,480 INFO org.glite.ce.commonj.authz.gjaf.ServiceAuthorizationChain - User CN=Liaw SyueYi 182693, OU=GRID, O=AS, C=TW not authorized for {http://www.gridsite.org/namespaces/delegation-2}getProxyReq

APEL multicore accounting

As many EGI user communities are now exploiting multicore hardware it is important for them that accounting correctly reflects the usage made of cores and cpus. At the December Operations Management Board (OMB) it was decided to ask all sites using the APEL client to configure it to publish the number of cores used by jobs.

To enable multicore accounting, you will need to edit the configuration file for the apel parser. This is the software which parses blah logs and batch logs to produce accounting records. The configuration file is usually found at /etc/apel/parser.cfg. In the section labelled [batch], change:

parallel = false

to

parallel = true

This will enable multicore reporting for all future accounting data. Please note that this does not change historical data. Also note that republishing old data is not sufficient to show multicore information - the log files will need to be reparsed. If you wish to republish old data with multicore enabled, please open a GGUS ticket with the APEL team so that we can help you with the process.

If you use the SGE parser, please be aware that it only reports on the number of processors used in a job. It does not report the number of nodes. If you know how to get around this limitation, then please get in touch with the APEL team at apel-admins@stfc.ac.uk.

The multicore accounting data can currently be seen here: http://accounting-devel.egi.eu/show.php?

Drill down to your site and select the grouping "Show data for: Submitting Host" as a function of: "Number of Processors".

Values of 0 mean the parallel option was false when the data were published. The Submitting Host is a new feature in the accounting portal which lets a site see in more detail which CEs are publishing.
