Hi,

Thanks to Matthew & Manning for Wonderful book (will much needed )

Well, I am in chapter 11 and looking at code. I checked sample Ch11_string_search on Windows and Linux couldn't get it to work.

1/ Program compiled on linux and windows (x64), but somehow vectoring code (string_search.cl)
2/ but "Number of occurrences of ..." for all are printed 0 (Zero)
3/ To be sure, I added few other functions like check device available (from Chapter #2) etc, they worked fine. Still Program finishes execution with device info etc. and "Number of occurrences of ..." for all are printed 0 (Zero)
4/ For debugging, I tested code in Intel OpenCL problem appears to be with "SDK Kernel <string_search> was not vectorized" message and comes specifically in context of
/* Iterate through characters in text */
for(int i=item_offset; i<item_offset + chars_per_item; i++) { >

/* load global text into private buffer */
text_vector = vload16(0, text + i);

Please provide any possible help. I tried to test code with both devices (Intel Sandy bridge i7 and Nvidia 525M) but same issue persists.

Thanks in advance.

Best Regards,
Aditya

Anyone, Any advice? Still stuck!

Thanks!
