Any updates on GPU apps for OSX? I have shut down SETI Beta for the summer or until a GPU app is released for OSX. Any hints on an ETA?
Eric how is it looking on the OSX GPU app. You said something about trying to make a version over the weekend. How did it go? Any updates on an ETA. Your's is the only project I have currently asking for GPU work. Otherwise I'm in a GPU shutdown due to summer heat.

I didn't go well in that it currently generates incorrect results. I'm trying to figure out why.

What build path do you use (what defines?)
Well Poke,Poke,poke....
Any updates? Waiting and have a machine ready to try it out when ever you are ready. Hope you are getting closer and the builds are getting better and better.

Not really any updates. I fixed one problem, and now it's segfaulting due to a buffer overrun in generate_time_noise_with_envelope(). I'm finding it hard to debug because every memory allocation appears to be an assigned subsection of a large buffer rather than individual allocations. And with so many #ifdefs its hard to tell what code is actually running.
There are also undoubtedly things that were #ifdefed out that should probably be in the compile.
If I had the time I'd go back to the original astropulse code and add the OpenCL code back into it. The original code was awful but I understood it more...
Regarding Raistmers' query...
-DUSE_FFTW -DUSE_CONVERSION_OPT -DUSE_INCREASED_PRECISION -DUSE_OPENCL -DOPENCL_WRITE -DCOMBINED_DECHIRP_KERNEL
#define SSE_LEVEL _sse3
#define USE_SSE3 1

I'm afraid it will be big waste of time cause OpenCL code augments optimized CPU code, you will need to rewirite quite a lot IMHO.
Some good IDE with active path highlighting should help a lot. What about smth like Eclipse or smth similar ? Under VS I have syntax highlighting and block hiding features that help a lot with code navigation.
#define SSE_LEVEL _sse3
#define USE_SSE3 1
SSE2 level should be used to match windows build. Will post windows defines in use ...

Unfortunately, I've been permanently damaged by vi. I did try an alternative development environment for a day a couple weeks ago. It reformatted some code without my knowledge. I checked it in. David got angry.

Full list of defines for Windows build:
OCL_ZERO_COPY;COMBINED_DECHIRP_KERNEL;OPENCL_WRITE;USE_VIRTUAL_ALLOC;AP_CLIENT;
WIN32;_MT;NDEBUG;_WINDOWS;_CONSOLE;HAVE_STD_MAX;HAVE_STD_MIN;HAVE_STD_TRANSFORM;
CLIENT;USE_CONVERSION_OPT;USE_SSE2;USE_FFTW;USE_INCREASED_PRECISION;
SMALL_CHIRP_TABLE;USE_OPENCL
Just asking how the OSX GPU app is going. I know you only have a small amount of time to work on this per week so I want to only bug you once per week. How is it going and any more luck in bug hunting. If I can help in any way besides having a GPU waiting let me know. Unfortunately I am not a programer so I can't help that way. Thanks for your time Eric!!
