OSX Multibeam OpenCL question

(1/14) > >>

Joe Fox:
Hi all,

I have been doing some work on the OSX OpenCL port of multibeam, and have run in to a roadblock. The code branch that I am using is setisvn sah_v7_opt/AKV8. I have gotten a successful build using xcode 5.0.2 using the readme included in the project, however when I execute the binary against the reference_work_unit.sah I get the following output:


--- Code: ---Used GPU device parameters are:
Number of compute units: 280
Single buffer allocation size: 64MB
Total device global memory: 1536MB
max WG size: 512
local mem type: Real
period_iterations_num=23
Error in mb oclFFT_2: -49
ERROR: OpenCL kernel/call 'non-strip fft' call failed (-49) in file /Users/joe/projects/seti/sah_v7_opt/AKv8/client/analyzeFuncs.cpp near line 3820.
Waiting 30 sec before restart...

--- End code ---


The full stderr.txt is attached if more info is needed.

Earlier versions of this code were working back in early August, but something changed and now I run in to this error -49. Unfortunately I don't know enough about cl to troubleshoot further. Any suggestions on where the problem may lie?

Thanks

#define CL_INVALID_ARG_INDEX                        -49

Maybe last changes for AP broke MB build. i'll check if it compiles for windows then will see.

Raistmer:
btw, what device you run on? 280 Cus ??? impressive...

Joe Fox:
Cool, thanks. This is on my 2013 macbook pro running OSX 10.9.5.

Thanks
-Joe Fox

Are you sure that you are using actual code from the svn repository ? From your stderr.txt : "MultiBeam_Kernels_r632.cl" Current svn revision is r2725.
