European VLBI Network of Radio Telescopes
- a killer application for Grid ? - Mike Garrett ([email protected])
FP6 GRID Meeting, March 2003.

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!
