Did anyone hear something about atropulse lately?

Sorry to sound ignorant, but what's Astropulse?

One of the first applications to make use of the new BOINC distributed computing framework is a project we call AstroPulse. This project will re-examine the existing SETI@home data tapes for a new type of signal radio pulses that only last for a microsecond.

This type of signal is different from those which would be caught by SETI@home. Since the pulses are so fast, they are broad-band signals. We need the full 2.5 MHz bandwidth for maximum sensitivity, whereas SETI@home breaks up this frequency band into 256 10 kHz sub-bands. Also, pulses travelling through the interstellar medium (the thin gas which fills the space between stars in our galaxy) become "dispersed," or stretched out in time. We can correct for this effect with a specialized algorithm (known as "coherent de-dispersion"), but it is very computation intensive, which is why this is a good distributed computing project.

there was a Beta Test also

but at this time the Application has stopped.

>Excellent question! It seems that astropulse has been ready to open in a few months for several years now.
