New Year and New Direction…

So it is New Years Day 2013 in New York.  I am home and not supposed to be “working” because it is new years day.  Regardless, I decide to work on Fake Oakleys the analysis of the FPGA@Home Cheap Ray Bans movement because it is not really work for me, it is fun. cheap nfl jerseys  My brother Terry walks into the room and I start explaining what I have found to him.  He then tells me, “Why not look at the SETI CUDA source code to see what functions they optimized?”.

I download it from subversion and try to compile it… it cheap nfl jerseys fails… of course, but I realize that I don’t need to run it, I just need to analyze it.  So I go to the seti_analyze function and I find a bunch of calls and determine which & functions are offloaded to the GPU!  Now all I have to do is determine if these functions are FPGA-acceleratable!

Here are the functions:

  • ChirpData
  • fftw_execute_dfts
  • GetPowerSpectrum
  • summax <= custom function written by CUDA people, likely to be a summation of different functions in Ray Ban Sunglasses the regular code
  • GaussFit
  • find_triplets
  • find_pulse

So, the CUDA code works by basically downloading the entire set of data points – which usually number 1,048,000 complex data points and then performing the analysis on the functions listed above on it and sending the results back to the host computer to do the rest of the analysis.

I think we are getting real close…

    So I’m thinking about purchasing a pretty top-notch fpga array using four Spartan6lx150 chips to mine Bitcoins, but I dont think it will be profitable over the long run because of the future of mining. If that makes no sense to you you may want to look it up or ignore it. So, I was looking at some other ways to use an fpga once it became obsolete for its originally intended purpose. This is very interesting to me and I’m going to keep an eye on it. Just how close do you think you are maybe as a percentage?

    This looks promising – I hope it turns out well! I'm not great at coding low level stuff but I do have two FPGAs I'd be happy to test things on.
