I'm hoping to get a memory upgrade soon.
I run *large* FFTs for SETI analysis, and that requires lots of memory, and increasing certain system parameters (SHMMAX). The "Next Generation" of my standard hardware platform will be a Core i7 920, overclocked as much as reasonable, with fast memory (6GB to 12GB). I'm doing multi radio astronomy and SETI analyses in parallel on data streams that may be arriving as fast as 16M samples per second. More CPU Igor, more CPU! Can't wait until Intel starts pushing hard on the new bus (QPI??), and brings out processors with more than 4 CPUs. -- Marcus Leech Principal Investigator, Shirleys Bay Radio Astronomy Consortium http://www.sbrac.org _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
