Heyho,

 

i try to transfer some data between Host and OpenCL Device during the Kernel Run,

by use of "cl_mem_use_persistent_mem_amd" i figured out that i can create an Pointer to an Buffer,

this works on my CPU but not on GPU (Programm crashes).

 

Is it even possible to transfer Data to the GPU during the Kernel-Run?

 

My System:

Ubuntu Linux 12.04 64 bit, AMD X4 CPU, AMD HD 7750, Catalyst 12.6

 

Thanks in advance,

Srdja
