Looking for an equivalent way of creating a sub buffer in OpenCL 1.0
Hello,
I am trying to invoke a kernel on a portion of a buffer that was computed on the device by a previous kernel. I tried to implement this using clCreateSubBuffer but this is not supported in OpenCL 1.0 and unfortunately I can't upgrade to a later release as the system is in a software-controlled, shared environment.
Has anyone come up with a way of doing this that doesn't ruin performance? The only thing that comes to mind immediately is to copy the portion to a new buffer, compute and copy the results back but I'm hoping there's a better way.
Thanks for your help.
