GLOBUS ACCOUNTING USING GRID-SAFE - DEMO

2. Key ideas & achievements
Elevator Pitch
Problem
You have Globus GRAM 5 grid-fronted (multiple) resources
You want to know who ran what & where across your site
You need to contribute this information to EGI’s central repository (i.e. APEL)
Key ideas & achievements
Support the ‘accounting’ pipeline
Straightforward installation and configuration
Easy extensibility, e.g. support multiple heterogeneous computing resources
Support for accepted/emerging open standards
It’s about ‘who ran what where?’

3. Introduction To Grid-SAFE
Accounting system based on OGF Usage Record & Resource Usage Service
Scientific-field agnostic
Developed at EPCC, Grid-SAFE project
Open standards support in SAFE project
Deployed on PRACE, ECDF Eddie cluster
UK NES developed batch file processing system for URs
IGE updated and extended it
Added GT5 parser
Integrated GT5 audit record capability
Packaged as part of Grid-SAFE for IGE v3.0

4. Grid-SAFE (Site) Architecture
Sub Site A
Sub Site B …
Sub Site n
GT5 RM
Via scheduled Cron job:
Outputs GT5 audit records
Batch2UR
Via scheduled Cron job:
Converts records to URs
GridSAFE RUPI Client
Via scheduled Cron job:
Uploads URs to Grid-SAFE
Very extensible – custom implementation classes can be specified for specific tasks
e.g. for different standards parsers: OGF UR v1.0, EMI CAR v1.0
Site
Aggregate records (APEL MessageFormat v0.2)
