---+ GPU_inspiral

GPU_inspiral is a low-latency, high performance many-core implementation of the matched-filter gravitational wave search algorithm, developed by the RMKI Virgo Group.
The base is an architecture and vendor independent OpenCL code. The sub algorithms implemented so far are the following:

   * template generation
   * PSD calculation
   * matched-filtering
   * chi2 calculation
   * clustering of events

---+ Performance
Performence test was done on a  2048 sec long data chunk, 500 template of 64 sec long was filtered. The code run on an Nvidia Tesla C2050. To produce the SNR time series it took ~17 sec
for =gpu_inpiral=, this has to be compare with the ~40 minutes necessary for =lalapps_inspiral= to produce the same result.

---++++!! This results a *speed-up factor of 2 orders of magnitude* !
