Release Notes for NorduGrid ARC 15.03 update 18
December 13, 2017
This is a bugfix release, addressing bugs discovered since release 15.03u17.
There are 3 fixed bugs in this version of ARC. These involve the infoprovider, EMI-ES submission interface,
and multicore jobs use of scratchdir. See more details below.
In addition memory leaks have been found and fixed, in Globus code and elsewhere in A-Rex.
NorduGrid ARC 15.03 has received an update to:
- core, clients, CE, Infosys and gridftp - from version 5.4.1 to 5.4.2
- documents - from 2.0.18 to 2.0.19
Gangliarc, Nagios plugins and metapackages are unchanged.
Detailed notes
The following issues were fixed:
ARC Server and core components
- Single node multicore jobs now use scratch disk by default (Bug 3694).
- Several memory leak fixes, and general cleanup and enhancements.
Accounting
Information system
- Negative VO numbers should no longer occur in GLUE2 VO ComputingShares (Bug 3686).
ARC Clients
- Jobs submitted via EMI-ES interface with non-dynamical output files will no longer fail due to missing delegations file.
Full delegation is now always done by default in EMI-ES (Bug 3693).
Nagios plugins
Fixed bugs:
Since ARC 15.03 update 17, the following bugs were fixed:
Known issues
- There is a memory leak when using Java API for multiple job submission with
files to BES interface.
- The CPU time is not measured correctly for jobs that kill the parent
process, such as some agent-based/pilot (e.g., ALICE)
- JURA will not publish records to the APEL on a standard Debian/Ubuntu
system, because the python-dirq package is not available for them. The
workaround is to build this package from source.
- When using ARC client tools to submit jobs to CREAM, only JSDL can be used
to describe jobs, and the broker type must be set to Null in the client.conf
file
- ARC GUI (arcjobtool) is not available yet, pending implementation of client
library changes.
- Standalone client tar-balls for Linux are not yet available.
- A-REX can under some circumstances lose connection with CEinfo.pl and go into an infinite loop. The only current workaround is to restart the a-rex service.
- twistd, the underlying engine for ACIX, sometimes logs into rotated ACIX log files.
While all log messages are correctly logged in the main log file, some rotated log
files may receive new log messages.
- submit-*-job do not have permission to write performance metrics to log.
- authorizedvo=<voname> will no longer create a list of VOs under each Share. As a consequence,
EMIES WS clients can no longer find a queue by VO name the same way as in previous versions
of ARC due to changes in the GLUE2 schema rendering.
