Which version are you using? There are now 3 ways for everyone to get free access to Intel(R) SDK for OpenCL Applications.
For more info please see: https://software.intel.com/en-us/articles/opencl-drivers. General EULAs are available for all of these packages.
I am using Linux (CentyOS 6.5). I have a Intel Xeon Phi in my workstation. I wanted to implement OpenCL on that and thats why I need Intel SDK for OpenCL. Are you talking about " Intel® SDK for OpenCL™ Applications 2016 R2 for Linux* (64 bit) (Driver components included)" ? I downloaded from the "Download Center " and got a mail saying "Thank you for downloading an Intel® Software Product trial." It would be very helpful if you could help me with the free access of SDK for OpenCL.
