HEY YA !

this version produces correct results with small differences
this is from cuda app :
Code:
<best_spike>
  <peak_power>22.561671618532</peak_power>
  <mean_power>1</mean_power>
  <time>2451239.5780686</time>
  <ra>8.3192064227348</ra>
  <decl>27.898178773406</decl>
  <q_pix>0</q_pix>
  <freq>1418974011.7011</freq>
  <detection_freq>1418983759.2021</detection_freq>
  <barycentric_freq>0</barycentric_freq>
  <fft_len>131072</fft_len>
  <chirp_rate>-0.90022989063243</chirp_rate>
  <rfi_checked>0</rfi_checked>
  <rfi_found>0</rfi_found>
  <reserved>0</reserved>
</best_spike>

and this is from default app :
Code:
<best_spike>
  <peak_power>22.561794281006</peak_power>
  <mean_power>1</mean_power>
  <time>2451239.5780686</time>
  <ra>8.3192064227348</ra>
  <decl>27.898178773406</decl>
  <q_pix>0</q_pix>
  <freq>1418975203.0489</freq>
  <detection_freq>1418975184.9249</detection_freq>
  <barycentric_freq>0</barycentric_freq>
  <fft_len>131072</fft_len>
  <chirp_rate>-0.90022989063243</chirp_rate>
  <rfi_checked>0</rfi_checked>
  <rfi_found>0</rfi_found>
  <reserved>0</reserved>
</best_spike>

as you see there are very small differencs in float numbers - different rounding Huh

an other data are same

Are the float/rounding differences enough to cause validation problem?

new binary :

- added a GPU PowerSpectrum - based on work by Hans Dorn ....
- optimised grid,block and thread scheduling over GPU for POwerSpectrum ....
- using pre-generated FFT plans ...

Elapsed time: 1159 seconds
Speedup     : -114.63%

Since I dont have a cuda card I cant test it out but I do have one question... Is CPU usage still 100% for this app?

Do you think you will be able to optimize for GPU use of pulse_find, GaussFit etc?
