CL_MEM_BANK flag

Altera_Forum · ‎08-21-2015

Hi everyone,

in my OpenCL project I am trying to assign a buffer to a specific memory bank using the flag CL_MEM_BANK_1_ALTERA in the clCreateBuffer function. What I don't understand is where I need to define these flag, since I am getting a compiler error (variable not defined).

Thanks,

Sergio

Hi Sergio,

Have you looked at the matrix multiplication example? Did you place it in the correct argument of the clCreatedBuffer function like below?

" buf[i] = clCreateBuffer(context, CL_MEM_BANK_1_ALTERA, buffer_size, NULL, &status); "

BTW: The flags are defined in cl_ext.h file and as long as you include CL/opencl.h it should be fine.

Cheers,

Ryan

Thanks Ryan. Now it works. I just forgot to include the .h.
