Hello, 

 

I need to allocate more than available from openCL today (1/4 of global memory). 

 

Device max memory allocation: 128 mega-bytes 

Device global mem: 512 mega-bytes 

 

 

How can I increase the max memory allocation limit? 

 

tks!

As far as i understand, that might not be possible. This might have to do with hardware limitations as well as the limits imposed by the driver/opencl- runtime.  

There is some specification of the available memory in the board_spec.xml file in the BSP. I have not seen what happens if the value is changed, so maybe that is a point to start.
