GD Group Report for C5-28-Mar-2008
===================================


LCG deployment:
---------------

- Total number of Sites (*): 242

- Software -> Num. Sites (*):
   gLite-3_1_0  -> 163
   gLite-3_0_2  ->  68
   gLite-3_0_0  ->   1
   LCG-2_7_0    ->   2
   unknown      ->   8

- Status -> Num. Sites (*):
   ok       -> 178
   degraded ->  12
   down     ->  52

- Average of concurrently running jobs during this week (+): ~25k

(*) Sites that are Certified _and_ Production _and_ Monitored
    by SAM:
       https://lcg-sam.cern.ch:8443/sam/sam.py

    To see this page one needs a grid certificate loaded in the browser.
    The calculation of the Site availability (Status) is described at:
    http://goc.grid.sinica.edu.tw/gocwiki/SAM_Metrics_calculation

    Software version is coming from the 'CE-sft-softver' CE test.
    Sites not supporting SAM 'CE' service, or not having sent results
    for this particular test during the last week, are counted
    as 'unknown'.

(+) Job statistics taken from GStat:
     http://goc.grid.sinica.edu.tw/gstat/
     http://goc.grid.sinica.edu.tw/gstat/total/GIISQuery_Usage_cpu_.html

     For the time being we do not report CPU numbers:
     1. Not all the reported CPUs are actually available for grid jobs.
     2. Sites with multiple CEs may have their CPUs double-counted.
     3. GStat includes sites that are not considered by the SFTs.



EGEE Pre-Production Service Coordination:
-----------------------------------------
Nothing to report this week.

CERN GRID Pre-Production Site (CERN_PPS):
-----------------------------------------
Nothing to report this week.

WLCG Transfer Service:
----------------------
Nothing to report this week.

SAM (Service Availability Monitoring):
--------------------------------------

* Closed a number of Savannah bugs, and released a new CA
  (Certificate Authority) test. This caused problems due
  to an obscure modification on one of the SAM UIs such that
  it started submitting jobs to WMS rather than RBs. The WMS
  server used (wms112.cern.ch), caused random false failures
  for many CEs in all EGEE ROCs.
  The WMS node is being checked, and SAM has reverted to
  using RBs only.
  Problem period: From Wednesday 19 21:00 to Tue 25 14:00.

* When reverting back to using RBs, some jobs were still being
  submitted using WMS-syntax, and this caused certain sites to
  experience job submission failures. This created some confusion,
  but was relatively harmless since one UI was working correctly,
  and the tests only threw warnings.

* In terms of bug fixes, an urgent patch was applied to ensure
  that SRMs publishing themselves as "srm" rather than "SRM" were
  not filtered from the SAM database.
  Note that this is a workaround for the fact that YAIM tagged
  things in a way not conforming to the Glue standard, which
  specifies that SRMs should be of type "SRM" and have a version
  attribute.
  A variety of variations exist, such as srm_v1, srm_v2, SRM,
  and srm.

* SAM sensors release 1.4.3-2 was installed in Validation on
  2008-03-26. The RPM was updated to contain CA v1.20. The
  submission framework was modified slightly to improve the
  retrieval of stdout messages from tests. This exposed a bug
  in HEPIX which required a workaround (HEPIX have since fixed
  the bug). This release also fixes a bug affecting SEE-GRID,
  who use environment variables within JDLs to change the
  location of test files on Worker Nodes.

* See

  for outage information.
