[Discuss-gnuradio] Flarging big FFTs

[Marcus D. Leech]

I can't use FFTs larger than about 180000 bins without getting "shared
memory allocation" errors in Gnu Radio.

Is there an easy fix for this?

For SETI work, being able to (for example) compute an 8 million point
FFT for an 8Msps signal gives you 1Hz
  resolution.  But I can't seem to get anywhere near this without the
allocator griping at me.
