Security concerns as CERN asking to open monitorinng to all CERN domain.


- Other
-- DiRAC: Jens 

Brian: "Tests with proxy delegation. Improved security in delegation. Tests with performance for parallel transfers."

Peter G:" Possible course on DIRAC for sysadmin. Same SNO+"


-- LIGO: Catalin 

Intervention on router connecting RAL network. Possible disruptions.

No News for LIGO.

Problem to find CVMFS repo.

-- LOFAR: George 

George on leave.

-- LSST: Alessandra 

Repo has been replicated on CVMFS Stratum-1.

-- LZ: David 

Sites involved: Data center at Imperial. No hardware funding. Sheffield and Endiburgh to be T2 sites.Other sites welcome.

Expected volume of data: 150 TB.


-- UCLan/GalDyn: Tom

Tom reported that GalDYn used  Northgrid to run 24,000 jobs for Q2 2015.

1. DIRAC server

S Fayer: "Glexec to be enabled by all for all small VOs"

Ewan reporting that procedure is trivial.

Steve proposing a discussion in TB.

Action on Imperial to email TB with requirements. Daniela emailed TB before the end of the meeting.


2. VO feedback for services and developers (e.g. Ganga)


Discussion about migration of Ganga to github. Target: immprove update support. Discussion to be followed in future meeting.


12:00 - 12:05 Actions & AOB 5' 

Ewan: Possible training course: Ganga submission, DIRAC data management.

Peter commented that we rely today on Tom's knowledge of operation with other VOs and asked if other sysadmins would like to be involved.

Matt and Steve would be interested.

David C asked if documentation would come out.


Peter G would like to have documentation and tutorial.

Steve commented that right now Ganga submission and DIRAC is not a requirement. He's tempted to understand.

Sam have tested it, and will give feedback.

Steve asked for a link stating how to start.

Tom posted the link
