I wrote an open-source OpenCL code (GitHub - fangq/mcxcl: Monte Carlo eXtreme for OpenCL (MCXCL)). It has been working well on a variety of GPUs and CPUs. However, I just tested it on a system (Ubuntu 14.04) with CUDA 7 and 3 graphics cards (GTX980Ti, GTX590 and GTX730), I got clBuildProgram error.
Strangely, when build the cl program on 980Ti, clGetProgramBuildInfo returned -2 (CL_BUILD_ERROR) status, the error message is “GeForce GTX 980 Ti” and nothing else; for 590 and 730, clGetProgramBuildInfo returned -1 (CL_BUILD_NONE).
The same code compiles and runs without problem on CUDA 6.0.
anyone has experienced moving from CUDA 6 to 7? how to debug this further?
