European VLBI Network of Radio Telescopes

- a killer application for Grid ? - Mike Garrett (garrett@jive.nl)

FP6 GRID Meeting, March 2003.

www.evlbi.org

All Telescopes sample data at 1 Gbit per second

Data stored on tape/disks, then shipped

to Processor

After days/weeks delay…

REAL TIME VLBI – 10 to 100 Gbps (total) transfer

rates

High Sensitivity High Reliability VLBI

FP6 GRID & VLBI

• Purpose built EVN Correlator is equivalent to ~ 2000 high-end dual processor PCs…

– Possible to use distributed computing to distribute and cross-correlate incoming telescope data across GRID ?

By end of 2003, Correlator can produce data at a rate of 160 Mbytes per second. Data sets of 100’s Gigabytes.

IN PRINCIPLE Possible to image enormous area of sky !

But ONLY With Ccomputing Facilities ON GRID dimensions!
