When Lofar Meets Stella

Posted by timothy on from the hill-people-rejoice-aloud dept.

Roland Piquepaille writes "The LOFAR (Low Frequency Array) telescope is a new IT radio-telescope which will use about 20,000 simple radio antennae when it's completed in 2008. At this time, it will cover an area with a diameter of 360 kilometers centered over the Netherlands. Its small radio antennae will detect radio wavelengths up to 30 meters, and because the ionosphere can bend some of these radio waves, the Lofar images might be somewhat blurry. So all the information captured by these antennae will be digitized and sent to a computing facility at a rate of 22 terabits/second today, and almost 50 terabits/second in 2010. This is the reason why Lofar needs Stella, an IBM supercomputer installed recently in Groningen, also in the Netherlands, to process signals from up to 13 billion light years from Earth. Stella consists of 12,000 PowerPC microprocessors and has a computing power of 27.4 teraflops. This overview contains more details and a picture about the Lofar-Stella interaction."

    A girl died in 1933 by a homicidal murderer. He buried her in the ground when she was still alive. The murdered chanted, "Toma sota balcu" as he buried her. Now that you have read the chant, you will meet this little girl. In the middle of the night she will be on your ceiling. She will suffocate you like she was suffocated. If you post this, she will not bother you. Your kindness will be rewarded.
