From the hello world example, I got: CL_DEVICE_GLOBAL_MEM_SIZE = 4294967296, which means 4GB global memory. I am using a nallatech 385a7 board, so why the global memory size I got from the example is not 8GB instead? (2banks of 4GB). Is it possible to use all the 8GB memory on board? Thanks.
I would recommend upgrading the BSP to the latest available version which supports 8GB of global memory on the 385 A7. The current version is R001.003.0001 and was tested in Quartus-II 126.96.36.199. You should contact Nallatech directly with this form to obtain access to the latest BSP: www.nallatech.com/support-lounge-access-request/ Thanks
