title: OpenCL : error -9999 on NVIDIA K20m
body: <p>I usually always find a solution on google (80% here), but this time this is unfortunately not the case. That's why I decided to create an account.</p>
  
  <p>I have written an OpenCL code which runs on different Intel and AMD CPU. It runs on an AMD RADEON HD7970 and NVIDIA Quadro FX 1800M too. However when I try to launch the code on an NVIDIA K20m I get the error -9999 with "clEnqueueNDRangeKernel".</p>
  
  <p>The most troubling is that the error occurs after 512 iterations (I guess 512 is a coincidence).</p>
  
  <p>I believe (but maybe it was just error -11) I have already seen this error but it was an error during building program and due to "clGetEventProfilingInfo". This time all profiling is comment.</p>
  
  <p>I'm looking for information about this error.<br/>
  Thank you in advance for your answers.</p>
