OpenCL, Ubuntu 14.04, Intel i3-4010U - clGetPlatformIDs return -1001

[regensburger__albert]

Hi all,

I have a problem that I cannot solve by my own, and I need some help.

I just downloaded and installed Intel SDK for OpenCL applications. I could compile some examples on Intel's website. However, the execution always fails because clGetPlatformIDs() always returns -1001.

Could someone tell me what I am doing wrong, or what I am missing, please?

My machine is:

• Processor: Intel i3-4010
• OS: Ubuntu 14.04
• Graphic: Intel HD 4400 (Haswell-ULT Integrated Graphics Controller)

Thank you in advance

Hi Albert,

Are you able to run capsbasic example: https://software.intel.com/en-us/articles/caps-basic ?

Could you please run it and post the output?

Also, did you install GPU and CPU OpenCL drivers: https://software.intel.com/en-us/articles/opencl-drivers#latest_linux_driver and https://software.intel.com/en-us/articles/opencl-drivers#core_xeon ?

I install Centos7 and solve the problem,but CL_DEVICE_TYPE_GPU is 0,is there anyone who can help me?

BYW,I have check http://registrationcenter-download.intel.com/akdlm/irc_nas/11396/SRB5.0_intel-opencl-installation.pdf
