Hello everybody,

 

First of all, i would like to thank Chris and AMD as we managed to get a transfert between FPGA and GPU and got very good numbers for the transfer speed.

 

However, i have a concern about the size it seems we can allocate on the GPU with clMakeBufferResidentAMD:

 

in my tests, i get an error "CL_OUT_OF_RESOURCES" on clMakeBuffersResidentAMD whenever i try to allocate more than 100 659 200 bytes of memory, and thus getting 0 for marker and surface adress.

 

Is it normal?

 

thanks for any answer,

regards
