It’s hard work discovering the secrets of the universe, and now the Einstein@Home distributed computing project has broken the petaflop – the compute power of approximately 61 million iPad 2 processors – barrier in its quest to find pulsars and gravity waves.
“But,” you might say, “Supercomputers can do circles around that!” True, but if you look at a list of the top 500 supercomputers, only the top 23 run in the petaflop range. With such a large volume of collected scientific data to sift through, having a petaflop of extra computing resources is nothing to laugh at. And overall, distributed computing contributes much more than that.
At the time of publication, the distributed computing projects based on the Berkeley Open Infrastructure for Network Computing (BOINC) software system showed a daily average of 7.2 petaflops across more than 720,000 computers. For perspective, the combined power of BOINC-based projects would rank fifth on the list of top supercomputers.
Distributed and grid computing networks like Einstein@Home, SETI@Home and the World Community Grid provide much-needed, cheap computing power for workload-intensive research projects, and cut down on the costs of building supercomputers. The grid model can also provide scalability and redundancy that a data center would struggle to achieve.
So which will it be: Finding alien intelligence with SETI, proving Einstein’s theories or helping to predict the climate?
