[Starpu-devel] OpenCl and Starpu

[Gabriel Piscoya Davila <gpiscoya2013@hotmail.com>]

Hello
My name is Gabriel and i am trying to use Starpu with Opencl. When show the starpu_machine_display there are no opencl devices recognized but i have made the proper configurations on starpu (I guess). 

The configuration i've made is:

./configure -enable-stats -enable-maxbuffers=50  

and the result is:

configure:

    CPUs   enabled: yes
    CUDA   enabled: no
    OpenCL enabled: yes
    SCC    enabled: no
    MIC    enabled: no

    Compile-time limits
    (change these with --enable-maxcpus, --enable-maxcudadev,
    --enable-maxopencldev, --enable-maxmicdev, --enable-maxnodes,
        --enable-maxbuffers)
        (Note these numbers do not represent the number of detected
    devices, but the maximum number of devices StarPU can manage)

    Maximum number of CPUs:           64
    Maximum number of CUDA devices:   0
    Maximum number of OpenCL devices: 8
    Maximum number of SCC devices:    0
    Maximum number of MIC threads:    0
    Maximum number of memory nodes:   16
    Maximum number of task buffers:   50

    GPU-GPU transfers: no
    Allocation cache:  yes

    Magma enabled:     no
    BLAS library:      none
    hwloc:             yes
    FxT trace enabled: no
    StarPU-Top:        no

        Documentation:     no
        Examples:          yes

    StarPU Extensions:
           MPI enabled:                                 yes
           MPI test suite:                              no
           FFT Support:                                 no
           GCC plug-in:                                 no
           GCC plug-in test suite (requires GNU Guile): no
           OpenMP runtime support enabled:              no
           SOCL enabled:                                yes
               SOCL test suite:                             no
               Scheduler Hypervisor:                        no
               simgrid enabled:                             no
               ayudame enabled:                             no
           Native fortran support:                      no
           Native MPI fortran support:                  

configure:
WARNING: SOCL test suite will not be run as the environment variable SOCL_OCL_LIB_OPENCL is not defined.
To run the tests, you need to install the OCL implementation of ICD
(https://forge.imag.fr/projects/ocl-icd/ or Debian package ocl-icd-libopencl1)
and set the variable SOCL_OCL_LIB_OPENCL to the location of the libOpenCL.so.

then when I make the starpu_machine_diplay is shows

StarPU has found :
    4 CPU threads
        CPU 0
        CPU 1
        CPU 2
        CPU 3
    0 CUDA devices
    0 OpenCL devices

topology ...
core 0    PU 0    CPU 0    
core 1    PU 1    CPU 1    
core 2    PU 2    CPU 2    
core 3    PU 3    CPU 3    

 

I dont know where could be the error, could you give me some help??

thanks.
