Hi, I have a successful installation of Nvidia drivers and cuda which is confirmed by "nvcc -V" and "nvidia-smi".
after configuring the openmpi with "./configure --with-cuda --prefix=/home/umashankar/softwares/openmpi-2.0.3" "make all install" and after exporting paths , I ended up with an error as following mpirun: /usr/local/cuda/lib64/libOpenCL.so.1: no version information available (required by /home/umashankar/softwares/openmpi-2.0.3/lib/libopen-pal.so.20) tried to lookup online for the solution, but none of them helped me. please have a look at this https://github.com/mbevand/silentarmy/issues/63 which suggests to edit the opencl headers and library path before make, but i could not find where should i change. By the way I have installed OpenCL through sudo apt-get nvidia-opencl-dev and sudo apt-get install nvidia-opencl-icd-375 and the null point behaviour of "clinfo" gave me this NULL platform behavior clGetPlatformInfo(NULL, CL_PLATFORM_NAME, ...) No platform clGetDeviceIDs(NULL, CL_DEVICE_TYPE_ALL, ...) No platform clCreateContext(NULL, ...) [default] No platform clCreateContext(NULL, ...) [other] Success [NV] clCreateContextFromType(NULL, CL_DEVICE_TYPE_CPU) No platform clCreateContextFromType(NULL, CL_DEVICE_TYPE_GPU) No platform clCreateContextFromType(NULL, CL_DEVICE_TYPE_ACCELERATOR) No platform clCreateContextFromType(NULL, CL_DEVICE_TYPE_CUSTOM) No platform clCreateContextFromType(NULL, CL_DEVICE_TYPE_ALL) No platform So please can any one through some light on where i'm going wrong? is it with Mpirun, or with opencl ? thank you, Umashankar
