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

sahcuda.rar (224.16 KB - downloaded 15 times.)

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

<peak_power>22.561671618532</peak_power>
<peak_power>22.561794281006</peak_power>

<freq>1418974011.7011</freq>
<freq>1418975203.0489</freq>

<detection_freq>1418983759.2021</detection_freq>
<detection_freq>1418975184.9249</detection_freq>

Small???

yeah this is small to compare with totally different previous results .... Grin

and yeah this problem by validation ....

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 ...

TECHNOLOGY PREVIEW !!! TESTING VERSION !!!!

sahcuda.rar (226.48 KB - downloaded 30 times.)

wow!

faster than previous?

okay now new code :

important !!!! now its validated !!!!!!!!!!

Code:

------------
sahcuda.exe / testWU-1.wu :
Started at : 17:57:49
Ended at : 18:17:08
Elapsed time: 1159 seconds
Speedup : -114.63%
Ratio : 0.47 x

Result : strongly similar.

speed is compared against last cruncher app

Seriously ?

try in knabench and will see

I can not understand how use knabench.....
not user-friendly packet...

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?
