OpenCL error -1001

[Deep_J_]

Hi

I am using two Intel Xeon Phi co-processors on a machine having RHEL 7.2 . I have installed MPSS 3.7.2 & Intel sdk for openCL 2016 6.2.0. 

Both processors are being shown using micinfo command but when I tried to run samples given at https://software.intel.com/en-us/intel-opencl-support/code-samples they got compiled but they are not running properly as I get error -1001 which is thrown when no platforms are available.

Hi, It sounds like you need the OpenCL Drivers installed which are available from:

I concur with joshbowden.

I'd like to add that you will need to install the deprecated 14.2 driver, as that is the latest release that included Xeon Phi support. The RPM I normally install is opencl-1.2-intel-mic-4.5.0.8

Also note that OpenCL on Xeon Phi is no longer supported by Intel, but I can confirm that the (OpenCL 1.2 !) driver above still works.

HTH,

JJK
