1. Distributed Correlation in Fabric Kiwi Team PSNC

2. Experiment creation phase

3. Correlation phase

4. E-VLBI System – communication

5. 2. Submitting the observation workflow

6. 3. Workflow execution Divided into the following phases: 1.Chunking data from radio telescopes 2.Submitting chunked data sets for correlation 3.Archiving the correlated data sets

7. (1) Wf execution: chunking

9. (1) Wf execution: preparing environment

10. (1) Wf execution: sending chunks

11. (2) Wf execution: correlation First data chunks are available Step, where the real correlation takes place Computation on the Grid resources

12. (2) Wf execution: correlation

13. (2) Wf execution: scheduling scheduling correlation jobs with Correlation Node..

14. (2) Wf execution: correlation

15. (3) Wf execution: archive First data sets have been correlated Store correlated data with Correlated Data Service (CDS) Clean up the Grid resources

16. (3) Wf execution: archive

18. Fabric results 25 minutes of data Successful correlation with 2 clusters (PSNC) One File Server (Jive) Stations: Westerbork, Medicina, Torun, Cambridge

19. Correlation testbed

20. Correlation time vs chunk size
