title: Maximum memory allocation on openCL CPU
body: <p>I have read that there's a limit to the maximum memory allocation to around 60% of device memory, and these can be changed by modifying the <code>GPU_MAX_HEAP_SIZE</code> and <code>GPU_MAX_ALLOC_SIZE</code> environment variables for GPU.  </p>
  
  <p>I am wonder if the AMD SDK has something similar for the CPU if I want to raise the limit of memory allocation?</p>
  
  <p>For my current configuration, it returns the following:</p>
  
  <p><code>CL_DEVICE_MAX_MEM_ALLOC_SIZE = 2973.37MB</code></p>
  
  <p><code>CL_DEVI_CEGLOBAL_MEM_SIZE = 11893.5MB</code></p>
  
  <p>Thanks.</p>
