From this thread, http://devgurus.amd.com/thread/158397, I 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 GPU_MAX_HEAP_SIZE and GPU_MAX_ALLOC_SIZE environment variables. I am wonder if amd has something similar for the CPU if I want to raise the limit of memory allocation?
I have 16GB in my box and I see:
|Global memory size:||16829710336|
I am not sure if it is possible to increase it over physical memory? is that what you want?
