Hi James, Andy,

thanks for the script.

The script still uses the edg-* commands to submit jobs to the GRID. As 
far as I know, EDG resource brokers are slowly being phased out, in 
favour of gLite workload management servers. This means the edg-* 
commands have to be replaced by glite-wms-* in the near future. Depending 
on which resource broker you used, Andy, you might have had one that has 
already decommissioned its EDG resource brokers? RAL Tier1 for example 
will drain them on 28 Nov. (see email attached at the bottom)

We should probably switch the script to using glite-wms already, I am 
testing it now and will let you know whether it works and which changes 
are needed. I am also still pondering whether I am going to use such a 
script in the Rivet validation tool, or whether the grid-submission 
capabilities should be part of the tool itself. I am in favour of the 
latter, as the tool will have to do some simple monitoring and output 
retrieval as well, which is maybe beyond the scope of a simple RivetGrid 
script.

Cheers,
Frank


Subject: lcg-RB closure at RAL-LCG2

Dear GridPP UK users,

Following a successful trial period of the gLite WMS, we are announcing
the decommissioning of the EDG Resource Brokers located at RAL Tier1
(lcgrb01, lcgrb02 and lcgrb03.gridpp.rl.ac.uk)

On Friday 28 November 2008 12:00 BST, the RBs will be put into 'drain'
mode, which means that they will refuse to accept new jobs. The already
submitted jobs will continue to run and users will be able to retrieve
the job outputs until Monday 8 December 14:00 BST. On Tuesday 9 December
10:00 BST the RBs will be stopped and re-deployed by Fabric team.
Monitoring of these machines as lcg-RB will become obsolete and the
existing logs will be preserved accordingly with the RAL Tier1 policies.

Users are advised to switch job submission via the glite WMS server at
RAL Tier1: lcgwms01 and lcgwms02.gridpp.rl.ac.uk. If submitting via the
command line, you should now start using the glite-wms-* utilities (e.g.
glite-wms-job-submit, rather than edg-job-submit) using appropriate
configured front ends machines or proper configuration files.

If you encounter any problems, please email lcg-support at gridpp.rl.ac.uk

Best regards,
Catalin Condurache
RAL Tier1 Grid Services Team
