Fixed bugs:
Since ARC 15.03 update 1, the following bugs were fixed:
- 3047 support for sessiondir=... drain option is missing in new infoproviders
- 3424 Continuous unterminated infoprovider due to Condor.pm and ARC0mod.pm errors lead to bdii broken pipe error
- 3462 problems with scan-SLURM-job script
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.
- Bug 2905 is solved using workaround. Source of problem is not yet
identified.
- JURA cannot send/store local user ids
- 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.
